Observing Highlights
Venus and the Moon
Monday, March 7, 6:00 a.m. EST
Venus and the moon rise around 6 a.m., about 45 minutes before sunrise, less than 3 degrees apart.
Double shadow transit on Jupiter
Monday, March 7, 7:28–8:58 p.m. EST
Shadows of Io and Europa cross Jupiter simultaneously. Because this is only 10 hours before opposition, the moons almost overlap their shadows.
Jupiter at opposition
Tuesday, March 8, 6:00 a.m. EST
Jupiter is exactly opposite the Sun in the sky, and is visible all night.
Total eclipse of the Sun
Wednesday, March 9
The path of totality crosses the islands of Sumatra, Borneo, Sulawesi, and Halmahera in Indonesia, before heading to across the Pacific Ocean. It is seen here from Palembang on Sumatra. Partial phases of the eclipse will be visible in Southeast Asia, China, Japan, Papua-New Guinea, all of Australia except the southeast, Alaska, and Hawaii.
Double shadow transit on Jupiter
Monday, March 14, 10:22–11:34 p.m. EDT
Shadows of Io and Europa cross Jupiter simultaneously.
Equinox
Sunday, March 20, 12:30 a.m. EDT
The Sun crosses the celestial equator traveling north, marking the vernal equinox in the northern hemisphere. Days and nights are of equal length. The Sun rises due east and sets due west.
Jupiter 2 degrees north of Moon
Monday/Tuesday, March 21/22, 12 midnight EDT
There is a close conjunction between the planet Jupiter and the Moon right at midnight.
Double shadow transit on Jupiter
Tuesday, March 22, 12:23–2:31 a.m. EDT
Shadows of Io and Europa cross Jupiter simultaneously.
Penumbral eclipse of the Moon
Wednesday, March 23, 6:47 a.m. HADT
The Moon will dip briefly into the Earth’s faint penumbral shadow, best seen from the Pacific Ocean and surrounding territories. Here seen from Honolulu, Hawaii.
Double shadow transit on Jupiter
Wednesday, March 23, 7:47–8:59 p.m. EDT
Shadows of Io and Ganymede cross Jupiter simultaneously. Europa is in occultation behind Jupiter and won’t reappear from Jupiter’s shadow until 9:46 p.m. EDT. Thus from 6:22 p.m. until 9:46 p.m. Io and Ganymede will be in front of Jupiter and Europa will be behind Jupiter or in its shadow, leaving Callisto as the only moon visible in small telescopes.
Double shadow transit on Jupiter
Tuesday, March 29, 3:00–4:25 a.m. EDT
Shadows of Io and Europa cross Jupiter simultaneously.
Planets
Mercury is well placed low in the morning sky at dawn for the first half of the month. This apparition is more favorable for observers in the Southern Hemisphere because of the angle the ecliptic makes with the horizon.
Venus continues to shine brightly at dawn all month, but is dropping towards the Sun.
Mars, in the morning sky, moves from Libra to Scorpius on the 13th. Its disk grows from 9 to 11 arc seconds during the month, as it moves towards opposition on May 22. Observers with good telescopes should be able to see some of the dark markings on Mars’ surface this month.
Jupiter is at opposition on March 8, so is visible all night. There are a number of interesting double shadow crossings by Jupiter’s inner three moons.
Saturn is well placed in Ophiuchus, rising near midnight. Its rings are now spread widely, making it a beautiful sight in a small telescope.
Uranus is too close to the Sun to be observed this month.
Neptune is also too close to the Sun to be observed all month.
