Solar Analemma. This outstanding image from Alexandra Hart taken over a period of 4 years charts the midday position of the sun in the sky throughout the year. The north–south component of the analemma results from the change in the Sun's declination due to the tilt of Earth's axis of rotation. The east–west component results from the nonuniform rate of change of the Sun's right ascension, governed by combined effects of Earth's axial tilt and orbital eccentricity.

Merry Christmas, Happy New Year and looking forward to a great solar cycle 25!

This is really bad seeing

This sky is from last week. It is the most dramatic sky I've ever seen from my back yard. The SSM (acquired recently) indicated that volcano season has arrived.
Hello, my name is Pon, nice to meet you
