The Constellation Hydra

Post by Christopher K. »

This longest of constellations begins right below Cancer and to the lower right of Regulus. There are few bright stars within Hydra's boundaries; Alphard is a tad brighter than Polaris and class K. Alphard can be found the next few nights about forty-five degrees up in the south-southwest.

One can spot Alphard at 8:45pm in the southeast, halfway between the horizon and the top of the sky. We actually only have about ninety minutes of good forecast tonight...until 10:15pm, after which the clouds increase and the humidity becomes unbearable.

Here is the NOAA forecast for 9:30pm CDT...
precipitation potential, 2%
sky cover, 52%
relative humidity, 82%
temperature, 23˚C
surface wind, S 14 km/h

Danko's Clear Dark Sky states that during HRPO's viewing time the transparency rating will be "above average" (3 out of 5) and the seeing rating will be "poor" (2 out of 5).
