CAS Sky Notes for February 2023

Mercury:  Mercury is still a morning object throughout most of the month. However, as its declination is around -200 or worse, it will be very low in the sky and hard to see.  It’s probably best to wait until April to see it in the evening sky, when it will be better placed.

Venus:  This is now an evening object and becoming increasingly easy to observe.  It starts the month with a low declination of -11 degrees, but by the end it is nearly +4 degrees, making it significantly higher in the evening sky.  Its magnitude remains around – 3.9 throughout.  The phase decreases from 90% to 85%, although the angular diameter increases only a little to 12 arc seconds.
