Events of interest for June ….

June – Many thanks again for all your contributions to the group. Don’t ever forget, there is no such thing as a daft question in here. Noctilucent Cloud (NLC’s) season has begun again so don’t forget to visit out sister group “AUK – Aurora UK” for reports on activity.
There are a few changes in this months “What’s Up” and I am trying to research as much upcoming activity as possible. There will be more postings on upcoming Deep Sky Objects (DSO’s) which are best placed for viewing. This is in part due to my own observatory now being functional and remoted and this also provides me some steerage on upcoming events.

June 02 – STAR CLUSTER – The Hercules globular cluster (M13, NGC 6205; mag 5.8) will be well placed, high in the sky. It will reach its highest point in the sky at around midnight local time. At a declination of 36°27’N, it is easiest to see from the northern hemisphere but cannot be seen from latitudes much south of 33°S. From Scarborough, it will be visible all night. It will become visible around 00:20 (BST), 71° above your south-eastern horizon, as dusk fades to darkness. It will be lost to dawn twilight around 01:41, 70° above your south-western horizon. At magnitude 5.8, M13 is quite faint, and certainly not visible to the naked eye, but can be viewed through a pair of binoculars or small telescope.

June 03 – STAR CLUSTER – The globular cluster M12 (NGC 6218; mag 6.7) in Ophiuchus will be well placed, high in the sky. It will reach its highest point in the sky at around midnight local time. At a declination of 1°56’S, it is visible across much of the world; it can be seen at latitudes between 68°N and 71°S. From Scarborough, it will be visible all night. It will become visible around 00:25 (BST), 33° above your southern horizon, as dusk fades to darkness. It will then reach its highest point in the sky at 01:03, 33° above your southern horizon. It will be lost to dawn twilight around 01:36, 33° above your southern horizon. At magnitude 6.1, M12 is quite faint, and certainly not visible to the naked eye, but can be viewed through a pair of binoculars or small telescope.

June 04 – SATURN – Saturn will enter retrograde motion, halting its usual eastward movement through the constellations, and turning to move westwards instead. This reversal of direction is a phenomenon that all the solar system’s outer planets periodically undergo, a few months before they reach opposition. The retrograde motion is caused by the Earth’s own motion around the Sun. As the Earth circles the Sun, our perspective changes, and this causes the apparent positions of objects to move from side-to-side in the sky with a one-year period. This nodding motion is super-imposed on the planet’s long-term eastward motion through the constellations.

June 06 – STAR CLUSTER – The globular cluster M10 (NGC 6254; mag 6.6) in Ophiuchus will be well placed, high in the sky. It will reach its highest point in the sky at around midnight local time. At a declination of 4°05’S, it is visible across much of the world; it can be seen at latitudes between 65°N and 74°S. From Scarborough, it will be visible all night. It will become visible around 00:51 (BST), 31° above your southern horizon, as dusk fades to darkness. It will then reach its highest point in the sky at 01:01, 31° above your southern horizon. It will be lost to dawn twilight around 01:17, 31° above your southern horizon. At magnitude 6.6, M10 is quite faint, and certainly not visible to the naked eye, but can be viewed through a pair of binoculars or small telescope.

June 07 – MOON – The Moon will pass first quarter phase, appearing prominent in the evening sky and setting in the middle of the night. From Scarborough , it will become visible around 22:02 (BST), 34° above your south-western horizon, as dusk fades to darkness. It will then sink towards the horizon, setting at 02:14. At this time in its monthly cycle of phases, it appears almost exactly half illuminated. The Moon orbits the Earth once every four weeks, causing its phases to cycle through new moon, first quarter, full moon, last quarter, and back to new moon once every 29.5 days. As it progresses through this cycle, it is visible at different times of day. At first quarter, it appears high in the sky at sunset before sinking towards the horizon and setting in the middle of the night. Over coming days, the Moon will set later each day, becoming visible for more of the night. Within a few days, it will not make it very far above the eastern horizon before nightfall. By the time it reaches full phase, it will be visible for much of the night, rising at around dusk and setting at around dawn.

June 10 – METEORS – The Daytime Arietid meteor shower will be active from 14 April to 24 June, producing its peak rate of meteors around 10 June. Over this period, there will be a chance of seeing Daytime Arietid meteors whenever the shower’s radiant point – in the constellation Aries – is above the horizon, with the number of visible meteors increasing the higher the radiant point is in the sky. Seen from Scarborough , the shower will not be visible before around 02:04 each night, when its radiant point rises above your eastern horizon. It will then remain active until dawn breaks around 03:31. The radiant point culminates (is highest in the sky) after dawn – at around 11:00 BST – and so the shower is likely produce its best displays shortly before dawn, when its radiant point is highest. At this time, the Earth’s rotation turns Scarborough to face optimally towards the direction of the incoming meteors, maximising the number that rain vertically downwards, producing short trails close to the radiant point. At other times, there will be fewer meteors burning up over Scarborough, but those that do will tend to enter the atmosphere at an oblique angle, producing long-lived meteors that may traverse a wide area of the sky before completely burning up. The shower is expected to reach peak activity at around 21:00 BST on 10 June 2022, and so the best displays might be seen before dawn on 11 June and after the radiant rises on 11 June. At its peak, the shower is expected to produce a nominal rate of around 50 meteors per hour (ZHR). However, this zenithal hourly rate is calculated assuming a perfectly dark sky and that the radiant of the shower is situated directly overhead. In practice, any real observing sight will fall short of these ideal conditions. The number of meteors you are likely to see is thus lower than this, and can be estimated using the ZHR formula. From Scarborough, the radiant of the shower will appear at a peak altitude of 9° above your horizon, and on the basis of this, we estimate that you are only likely to see only around 8 meteors per hour, even at the shower’s peak, since the radiant will be relatively low in the sky. The Moon, in Virgo, will be only 3 days away from full phase at the shower’s peak, presenting significant interference throughout the night. However, it will be well separated from the shower in the sky, rising no higher than 26° above the horizon and lying 158° away from the shower’s radiant. If you select an observing site where it is possible to conceal the Moon behind a wall or other obstruction, it may be possible to preserve a reasonable degree of night vision. The radiant of the Daytime Arietid meteor shower is at around right ascension 02h50m, declination 24°N.

June 14 – FULL MOON – The Moon will be located on the opposite side of the Earth as the Sun and its face will be will be fully illuminated. This phase occurs at 11:52 UTC. This full moon was known by early Native American tribes as the Strawberry Moon because it signaled the time of year to gather ripening fruit. It also coincides with the peak of the strawberry harvesting season. This moon has also been known as the Rose Moon and the Honey Moon. This is also the first of three supermoons for 2022. The Moon will be near its closest approach to the Earth and may look slightly larger and brighter than usual.

June 16 – MERCURY – The planet Mercury reaches greatest western elongation of 23.2 degrees from the Sun. This is the best time to view Mercury since it will be at its highest point above the horizon in the morning sky though only at 7° above the horizon. Look for the planet low in the eastern sky just before sunrise.

June 18 – MOON/SATURN – The Moon and Saturn will share the same right ascension, with the Moon passing 4°16′ to the south of Saturn. The Moon will be 19 days old. At around the same time, the two objects will also make a close approach, technically called an appulse. From Scarborough, the pair will be visible in the dawn sky, rising at 00:25 (BST) – 3 hours and 59 minutes before the Sun – and reaching an altitude of 19° above the southern horizon before fading from view as dawn breaks around 03:51. The Moon will be at mag -12.4, and Saturn at mag 0.5, both in the constellation Capricornus. The pair will be too widely separated to fit within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.

June 21 – MOON – The Moon will pass last quarter phase, rising in the middle of the night and appearing prominent in the pre-dawn sky. From Scarborough, it will be visible in the dawn sky, rising at 01:26 (BST) – 2 hours and 58 minutes before the Sun – and reaching an altitude of 18° above the south-eastern horizon before fading from view as dawn breaks around 03:51. At this time in its monthly cycle of phases, it appears almost exactly half illuminated. The Moon orbits the Earth once every four weeks, causing its phases to cycle through new moon, first quarter, full moon, last quarter, and back to new moon once every 29.5 days. As it progresses through this cycle, it is visible at different times of day. At last quarter, it rises in the middle of the night and appears high in the sky by dawn. It sets at around lunchtime. Over coming days, the Moon will rise later each day, so that it is visible for less time before sunrise and rises less far above the eastern horizon before dawn. By the time it reaches new moon, it will rise at around dawn and set at around dusk, making it visible only during the daytime.

June 21 – MOON/JUPITER – The Moon and Jupiter will share the same right ascension, with the Moon passing 2°44′ to the south of Jupiter. The Moon will be 22 days old. At around the same time, the two objects will also make a close approach, technically called an appulse. From Scarborough, the pair will be visible in the dawn sky, rising at 01:17 (BST) – 3 hours and 7 minutes before the Sun – and reaching an altitude of 21° above the south-eastern horizon before fading from view as dawn breaks around 03:51. The Moon will be at mag -11.8, and Jupiter at mag -2.4, both in the constellation Pisces. The pair will be too widely separated to fit within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.

June 21 – SOLSTICE – The June solstice occurs at 09:05 UTC. The North Pole of the earth will be tilted toward the Sun, which will have reached its northernmost position in the sky and will be directly over the Tropic of Cancer at 23.44 degrees north latitude. This is the first day of summer (summer solstice) in the Northern Hemisphere and the first day of winter (winter solstice) in the Southern Hemisphere.

June 22 – MOON/MARS – The Moon and Mars will share the same right ascension, with the Moon passing 0°56′ to the south of Mars. The Moon will be 23 days old. At around the same time, the two objects will also make a close approach, technically called an appulse. From Scarborough, the pair will be visible in the dawn sky, rising at 01:39 (BST) – 2 hours and 45 minutes before the Sun – and reaching an altitude of 18° above the eastern horizon before fading from view as dawn breaks around 03:52. The Moon will be at mag -11.4, and Mars at mag 0.5, both in the constellation Pisces. The pair will be a little too widely separated to fit comfortably within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.

June 24 – MOON/URANUS – The Moon and Uranus will make a close approach, passing within a mere 2.8 arcminutes of each other. The Moon will be 25 days old. From Scarborough, the pair will be visible in the dawn sky, rising at 02:08 (BST) – 2 hours and 17 minutes before the Sun – and reaching an altitude of 13° above the eastern horizon before fading from view as dawn breaks around 03:52. The Moon will be at mag -10.5; and Uranus will be at mag 5.8. Both objects will lie in the constellation Aries. They will be close enough to fit within the field of view of a telescope, but will also be visible through a pair of binoculars.

June 28 – MERCURY – As seen from Scarborough , Mercury will reach its highest point in the sky in its Jun–Jul 2022 morning apparition. It will be shining brightly at mag 0.4. From Scarborough, this apparition will not be one of the most prominent and very difficult to observe, reaching a peak altitude of 7° above the horizon at sunrise on 29 Jun 2022.

June 27 – METEORS – The June Bootid meteor shower will be active from 22 June to 2 July, producing its peak rate of meteors around 27 June. Over this period, there will be a chance of seeing June Bootid meteors whenever the shower’s radiant point – in the constellation Bootes – is above the horizon, with the number of visible meteors increasing the higher the radiant point is in the sky. From Scarborough the radiant point is circumpolar, which means it is always above the horizon and the shower will be active throughout the night. The radiant point culminates (is highest in the sky) before nightfall – at around 22:00 BST – and so the shower is likely produce its best displays soon after dusk, when the radiant point is still as high as possible. At this time, the Earth’s rotation turns Scarborough to face optimally towards the direction of the incoming meteors, maximising the number that rain vertically downwards, producing short trails close to the radiant point. At other times, there will be fewer meteors burning up over Scarborough, and they will tend to enter the atmosphere at an oblique angle, producing long-lived meteors that may traverse a wide area of the sky before completely burning up. The shower is expected to reach peak activity at around 17:00 BST on 27 June 2022, and so the best displays might be seen after dusk on 27 June. The shower will peak close to new moon, and so moonlight will present minimal interference. The parent body responsible for creating the June Bootid shower has been identified as comet 7P/Pons-Winnecke. The radiant of the June Bootid meteor shower is at around right ascension 14h50m, declination 48°N.

June 28 – NEPTUNE – Neptune will enter retrograde motion, halting its usual eastward movement through the constellations, and turning to move westwards instead. This reversal of direction is a phenomenon that all the solar system’s outer planets periodically undergo, a few months before they reach opposition. This motion was known to ancient observers, and it troubled them as they could not reconcile it with models in which the planets moved in uniform circular orbits around the Earth, as they believed. The retrograde motion is caused by the Earth’s own motion around the Sun. As the Earth circles the Sun, our perspective changes, and this causes the apparent positions of objects to move from side-to-side in the sky with a one-year period. This nodding motion is super-imposed on the planet’s long-term eastward motion through the constellations.

June 29 – NEW MOON – The Moon will located on the same side of the Earth as the Sun and will not be visible in the night sky. This phase occurs at 02:53 UTC. This is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.
