LISTEN to this week’s Sky Report
This is the Griffith Observatory Sky Report for the period between June 1 and June 30, 2022. Here are the events happening in the sky of southern California.
Mercury rises at 5:04 a.m., PDT, and the sun rises at 5:43 a.m., PDT, on the 1st. Mercury is 9.25-percent illuminated and 11 arcseconds wide. On the 30th, Mercury rises at 4:30 a.m., PDT, and the sun rises at 5:45 a.m., PDT. Mercury is 71-percent illuminated and six arcseconds wide. Do not observe any planet when it appears close to the sun, for the danger to the eyes is great.
Venus rises at 3:50 a.m., PDT, on the 1st. The planet is 78-percent illuminated and 14 arcseconds wide. On the 30th, Venus rises at 3:46 a.m., PDT, with a disk 86-percent illuminated and 12 arcseconds wide. The disk of Venus slowly shrinks in size and becomes more fully illuminated as it moves to the far side of its orbit.
Mars rises at 2:31 a.m., PDT, on the 1st, and at 1:33 a.m., PDT, on the 30th. On the 3rd, Mars crosses from Pisces the Fishes to Cetus the Sea Monster and then crosses back into Pisces the Fishes on the 9th. The disk of Mars is 86-percent illuminated and increases in size from 6.4 arcseconds on the 1st to 7.2 arcseconds on the 30th. A telescope capable of magnification of 100x or more will be needed to show the disk and perhaps large surface features. On the 1st, Mars will be less than two degrees east of Jupiter. The planet moves east away from Jupiter every night afterwards. On the 22nd, the waning crescent moon appears three degree west of Mars.
Jupiter rises in Aquarius the Water Bearer at 2:24 a.m., PDT, on the 1st, and rises at 12:40 a.m., PDT, on the 30th. It moves into Cetus the Sea Monster on the 25th. A telescope capable of magnification 50x will show the Red Spot and the four bright Galilean moons, which can be seen moving back and forth, roughly in a line centered on Jupiter.
Saturn rises in Capricornus the Sea Goat at 12:41 a.m., PDT, on the 1st and at 10:45 p.m., PDT, on the 30th. The rings and Saturn’s largest moon Titan can be seen with a telescope capable of magnification 50x.
Uranus rises in Aries the Ram at 4:19 a.m., PDT, on the 1st and at 2:29 a.m., PDT, on the 30th. On the 15th, Uranus is at Right Ascension 2h 57m 34s with a declination of +16° 29ʹ 47ʺ. Uranus is only 3.5 arcseconds wide, and so a telescope with a magnification of 150x is needed to show its diminutive disk.
Neptune rises in Pisces the Fishes at 2:02 a.m., PDT, on the 1st and at 12:09 a.m., PDT, on the 30th. On the 15th, Neptune is at Right Ascension 23h 43m 50s and at declination -3° 1ʹ 31ʺ.
First quarter occurs on the 7th, full moon on the 14th, last quarter on the 20th, and new moon on the 28th.
SPECIAL EVENTS
Summer begins in the northern hemisphere, and winter in the southern hemisphere, at 2:14 a.m., PDT, on June 21. At this precise moment, the sun reaches its northernmost point on the ecliptic. This point and the time the sun meets it are called the summer solstice. Summer ends with the autumnal equinox on September 22.
The comet C/2017 K2 ( PanSTARRS ) may be visible with binoculars or a small telescope during June. The brightness of any comet can only be estimated, and it is not certain at this time whether it will be visible. The comet’s position can be determined accurately.
June 1 rises at 8:07 p.m. RA: 18h 21m 57s Dec: 9° 29ʹ 42ʺ Est. Mag.: +6
June 15 rises at 8:07 p.m. RA: 17h 58m 26s Dec: 6° 45ʹ 41ʺ Est. Mag.: +6
June 30 rises at 5:40 p.m. RA: 17h 28m 11s Dec: 2° 15ʹ 53ʺ Est. Mag.: +8
