Wednesday, November 21
Algol is at minimum light again, for a couple hours centered on 7:34 p.m. EST. Algol takes several additional hours to rebrighten.
Thursday, November 22
- The Moon is under the Great Square of Pegasus as the stars come out.
Jupiter's moon Io disappears into eclipse by Jupiter's shadow, barely beyond the planet's western edge, at 11:20 p.m. EST (8:20 p.m. PST). Jupiter's Great Red Spot transits the planet's central meridian around 10:16 p.m. EST.
Some pre-telescopic astronomy: Sometime between 6:30 and 8:30 this evening, depending on how far east or west you live in your time zone, bright Vega sinking in the northwest and bright Capella climbing in the northeast (well left of brighter Jupiter) will be at exactly the same height. How accurately can you time this event for your location? An astrolabe would help.
Saturday, November 24
- Look left of the Moon this evening, by a fist-width at arm's length or a little more, for the two or three brightest stars of Aries.
