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!

Feb 14, 2019 - Large Faint Prominence

It was a treat to see a large , albeit faint, prominence on the NW limb today. So satisfying to have imaged it Seeing and transparency : fair daystar Quark / ASI120MM-S / TMB92L cheers, Mike https://farm8.staticflickr.com/7900/47038793272_dc11b81632_b.jpg Capture 14_46_16_g4_ap4571_Drizzle30 by Mike...
