This is the Griffith Observatory Sky Report for the period between March 1 and March 31, 2022. Here are the events happening in the sky of southern California.

Mercury is in the morning sky. On the 1st, Mercury rises at 5:20 a.m., PST, and the sun rises at 6:22 a.m., PST. By the end of March, Mercury is close to the sun and not observable. Do not observe any planet when it comes close to the sun, for the danger to the eyes is great.

Venus is in the morning sky, low in the southeast. On the 1st, Venus rises at 3:48 a.m., PST., and the sun rises at 6:22 a.m., PST. On the 31st, Venus rises at 4:34 a.m., PDT, and the sun rises at 6:42 a.m., PDT. On the 1st, Venus is a crescent that is 38-percent illuminated and 31 arcseconds wide. On the 31st, Venus is 55-percent illuminated but is reduced in size to 22 arcseconds.

Mars starts March in Sagittarius the Archer.  On the 6th, Mars moves into Capricornus the Seagoat.  On the 1st, Mars rises at 4:09 a.m., PST, and on the 31st the planet rises at 4:26 a.m., PDT. Mars is south of Venus for most of March.  The disk of Mars is only five arcseconds wide and will not show any surface features through a telescope.

Jupiter starts March close to the sun and is unobservable. On the 31st, Jupiter rises in the morning sky at 5:55 a.m., PDT, and the sun rises at 6:42 a.m., PDT. A telescope capable of magnification 50x will show the Red Spot, and the four bright Galilean moons may be seen moving back and forth, roughly in a line centered on Jupiter.

Saturn rises in the morning sky at 5:23 a.m., PST, on the 1st. On the 31st, Saturn rises in the morning sky at 4:34 a.m., PDT. The rings and Saturn’s largest moon Titan may be seen with a telescope capable of magnification 50x.  Between the 27th and the 31st, Venus passes south of Saturn.

Uranus sets at 10:33 p.m., PST, on the 1st, and at 9:42 p.m., PDT, on the 31st. On the 15th, Uranus is at Right Ascension 2h 38m 0s with a declination of +15° 1ʹ 30ʺ. Uranus is only 3.5 arcseconds wide, and so a telescope with a magnification of 150x is needed to show its diminutive disk.

Neptune is close to the sun all March long and is unobservable.

New moon occurs on the 2nd, first quarter occurs on the 10th, full moon on the 18th, last quarter on the 24th, and new moon again on the 31st. We didn’t have any new moons in February because the month was too short. In March, we have two new moons.

SPECIAL EVENTS

Daylight Saving Time begins at 2:00 a.m. on March 13. All clocks must be set forward one hour in accordance with the phrase, “Spring forward, Fall back”.

Spring begins at 8:33 a.m., PDT, on March 20, signaling the beginning of spring in the northern hemisphere, which ends on June 21 with the summer solstice. The sun reaches the point where the ecliptic crosses the celestial equator. This point is called the vernal equinox.
