Some daily events in the changing sky for October 3 – 11.
Watch the Moon wax in the west from night to night, passing Venus and fainter Antares. (These scenes are drawn for the middle of North America. European observers: move each Moon symbol a quarter of the way toward the one for the previous date. For clarity, the Moon is shown three times actual size.)
Monday, October 6
Get a low-power scope onto Venus low in the west-southwest as twilight fades, and look for the wide double star Alpha Librae less than 1° to its north (upper right). This direction is correct at the time of twilight in North America. Venus itself is tiny (13″ wide) and gibbous.
Jupiter is the thing shining above the Moon this evening. Jupiter is now at eastern quadrature, 90° east of the Sun.
Tuesday, October 7
First-quarter Moon (exact at 5:04 a.m. EDT). This evening, Jupiter shines to the Moon's right.
Wednesday, October 8
Jupiter's moon Io emerges out of eclipse by Jupiter's shadow around 9:47 p.m. EDT, just east of the planet. A small telescope will show it gradually swelling into view.
Thursday, October 9
Early Friday morning, telescope users along the East Coast from Labrador to Florida can watch for whether the faint asteroid 225 Henrietta will occult (cover) a 10.4-magnitude star near the head of Cetus (not in Monoceros; that was an error).
Friday, October 10
The red long-period variable star W Lyrae should be about at its peak brightness (8th magnitude) this week.
Saturday, October 11
Jupiter's moon Ganymede disappears into eclipse by Jupiter's shadow around 9:39 p.m. Pacific Daylight Time, a little east of the planet. A small telescope will show it gradually fading away.
