Bob Moler's Ephemeris Blog

Arrrh!  This is Cap’n Bob with Ephemeris for Talk like a Pirate Day, Monday, September 19th.  I can’t keep this up. The sun will rise at 7:25.  It’ll be up for 12 hours and 20 minutes, setting at 7:46.   The moon, 1 day before last quarter, will rise at 11:35 this evening.

A reminder of the end of summer is located in the east around 9 p.m. It’s one of the great autumn constellations: Pegasus the flying horse of Greek myth.  Its most visible feature is a large square of four stars, now standing on one corner.  This feature, called the Great Square of Pegasus, represents the front part of the horse’s body.  The horse is quite aerobatic, because it is seen flying upside down.  Remembering that fact, the neck and head is a bent line of stars emanating from the right corner star of the square.  Its front legs can be seen in a gallop extending to the upper right from the top star of the square.  In Mythology Pegasus was born of the blood of Medusa, decapitated by the hero Perseus.
