The Ellensburg, WA sky for the week of November 1, 2025

Saturday: Happy Celtic New Year! Many historians think that November 1, known for the festival of Samhain, was the ancient Celtic New Year’s Day. Samhain, Old Irish for “summer’s end”, was a harvest festival that may have contributed to some of the customs of our current “holiday” of Halloween. Celebrate the Celtic New Year by observing Saturn in the southeastern sky, about a half fist held upright and at arm’s length to the lower left of the moon at 7:00 p.m.

Before you fall back on your bed tonight, set your clock back one hour to the real time. Daylight Saving Time ends early Sunday morning at 2:00 a.m. This means one more hour of sky watching in the evening because the Sun will set one hour earlier. Ben Franklin proposed the idea of “saving daylight” by adjusting our clocks way back in 1784. Daylight Saving Time was first utilized during World War I to save electricity. After the war, it was abandoned. It was reintroduced during World War II on a year-round basis. From 1945 to 1966, some areas implemented daylight saving and some did not. Also, it was not implemented with any uniformity as to when it should start and stop. The Uniform Time Act of 1966 codified the daylight saving rules. It also banished the “s” as the correct term is daylight saving time, not daylight savings time.

Sunday: Jupiter is one and a half fists above the east-northeastern horizon at 11:00 p.m. That means that Jupiter’s moons can be seen tonight, as well. In 2022, NASA’s Juno spacecraft sent back some of the most detailed images of Jupiter’s icy moon Europa. For more about the images and the rest of Juno’s mission, go to https://www.jpl.nasa.gov/news/nasas-juno-gets-highest-resolution-close-up-of-jupiters-moon-europa.

With a small telescope, you will be able to see all four of Jupiter’s largest moons tonight. Europa is about two Jupiter diameters to the upper right of Jupiter. Io, the closest of the bright moons to Jupiter, is about one Jupiter diameter to the lower left of Jupiter. Ganymede, the largest moon in the solar system, is about another Jupiter diameter beyond Io. Callisto, the farthest of the bright moons from Jupiter, is another three Jupiter diameters beyond Ganymede. Depending on the orientation and design of your telescope, these directions may be flipped. If your viewing conditions are excellent, you can see some of the moons with binoculars.

Monday: The two meteor showers centered in the constellation Taurus peak this week and next. That means there will be increased meteor activity in western Taurus.

The Southern Taurid meteor shower peaks for the next three nights. These are slow moving meteors that result in the occasional fireball. The Taurid meteor showers produce a few bright meteors every hour. The bright moon will obscure all but the brightest meteors through the end of the week. These meteors appear to come from a point in Taurus the bull, about two fists held at arm’s length to the right of the open star cluster called the Hyades. This point is about five fists above the south-southeast horizon at midnight. The “V” of the Hyades cluster points at the center of the Southern Taurid shower. Meteors are tiny rocks that burn up in the atmosphere when the Earth runs into them. These rocks are broken off parts of Comet 2P/Encke.

Tuesday: You’ve seen all the top 100 lists: top 100 ways to squat, top 100 Indonesian astronomers, etc. Now get excited for this week’s full Moon by reading about and finding some of the lunar 100. Go to http://goo.gl/ldGvH6. This list describes 100 interesting landmarks on the Moon that are visible from Earth. They are listed from easiest to see, starting with the entire moon itself at number 1, to most difficult (Mare Marginis swirls, anyone?). Stay up all night to binge watch the moon or just make a few observations a month. It’s your decision. It’s our moon. Start your viewing tonight at 7:00 p.m. when the Full Moon is three fists above the eastern horizon. I suggest starting with Mare Crisium, the circular, dark, basaltic plain in the upper right-hand portion of the moon. Items such as Crisium were named "Mare" by early astronomers who mistook them for seas, instead of the hardened lava beds that they really are.

Wednesday: Venus is a half a fist above the east-southeastern horizon at 6:00 a.m.

Thursday: Fomalhaut is one and a half fists above due south at 8:00 p.m.

Friday: Procyon, the brightest star in Canis Minor, the smaller dog, is one fist above due east at 11:00 p.m. Procyon means “before the dog” in ancient Greek, a fitting name because it always rises a few minutes before Sirius, nicknamed “the dog star”.
