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!

Today's Prominences & Active Region | HA | Nov 3rd 2018

Post by MalVeauX » Sat Nov 03, 2018 8:28 pm

Heya,

It's rained and been cloudy for days, but today around noon it cleared up. Usually my seeing is really bad this late in the day. I chanced it anyways. Captured today's fair prominences on the limb and an undesignated small active region in high resolution. I accidentally captured an occulting jet passing through the disc with the PST looking at full disc prominences too.
