Planets of the Month: November 2024

By Erich Karkoschka

Mercury is visible during dusk until the 25th around 6 pm, but it is low and difficult to find.

Venus is 20 degrees to the upper left of Mercury, setting around 8 pm. It is finally setting well after the end of twilight so that it becomes very obvious.

Saturn transits 50 degrees high around 8 pm and earlier later this month. Its rings are 5.4 degrees open, quite thin compared to the average view. From now until next spring, the rings will close completely.

Jupiter is rising in Taurus about when Saturn transits. Its magnitude of -2.8 can cause visible shadows on the ground at very dark sites.

Mars is rising around 10 pm, so that all bright planets are visible in the evening sky this month. Its magnitude goes negative, and its size becomes larger than 10 arc-seconds this month. This is the start of the good period to observe Mars with telescopes.

Uranus and Neptune are located between Jupiter and Saturn with Uranus closer to Jupiter and Neptune closer to Saturn. Uranus is just 6 degrees south of the Pleiades.

Minor planet (15) Eunomia of magnitude 8 transits 87 degrees high in Auriga.

The Moon is new twice this month, on the first and the last day of the month. It is first visible on the 3rd near Mercury, then on the next day near Venus. On the 12th, it occults Neptune at 6:40 pm, an event that lasts around 5 seconds compared to milliseconds for occultations of stars. On the night of the 15th-16th, it occults many stars of the Pleiades, although the Full Moon makes them hard to see. On the 27th, it occults Spica for most of North America, although Tucson is a near miss with both extremely close together at 4 am at the eastern horizon.

Comet C/2023 A3 Tsuchinshan-ATLAS moves from Ophiuchus to Aquila as it fades more and more from being visible in binoculars.

Planets of the Month: October 2024

By Erich Karkoschka

Venus is setting at 7:30 pm. Its visibility increases as the sun is setting earlier. On the 5th, the moon is 4 degrees from Venus. On the 25th, Venus passes Antares 3 degrees north.

Saturn is prominent all evening. Its rings are 10 times narrower than their 43 arc-seconds extent. Views of its six brightest satellites are best at the current geometry.

Jupiter becomes the brightest evening star as its rising times moves from 10 pm to 8 pm. It is at its northernmost location in Taurus, transiting 80 degrees high.

Mars rises just before midnight. Its motion in Gemini can be seen as the triangle with Pollux and Castor constantly changes shape. With magnitude 0 and 9 arc-second size, it becomes a worthwhile object in telescopes.

Uranus and Neptune are visible in the evening sky between Saturn and Jupiter. Uranus is easy to locate 5 degrees south of the Pleiades.

Comet Tsuchinshan-ATLAS (C/2023 A3) is magnitude 2 with a 5 degree tail. Starting on the 11th, it becomes visible and moves higher in the early evening sky, but fades rapidly towards the end of the month. The best compromise between altitude and magnitude may occur around the 16th, while the best dark sky without moonlight will start on the 19th. It moves from Virgo through Serpens into Ophiuchus at 7 degrees per day first, slowing to 2 degrees per day later. Its fast motion can be seen in a telescope within a minute.

The Draconid meteor shower may have a special high peak for half an hour around midnight of the 7th.
