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 Faint Proms | HA | Nov 7th 2018

Post by MalVeauX » Wed Nov 07, 2018 8:13 pm

Heya,

Cloudy day, but the seeing was pretty decent for the hour I was imaging. I was totally cloud covered this morning, but I had some sucker holes around noon, so I imaged then and figured I'd test my luck on the seeing. Turned out to be decent. The prominences are mostly quite feint, a large one is very feint and I had to really pull it out to even see it, I almost didn't notice it on GONG and only started to see it when I was looking at the limb in high resolution in the scope and saw a feint protuburence that looked like it was lifting away. No active regions. Just a few smaller filaments and a filaprom floating on the surface.

Beautifully processed Marty, I like to see the spicule edge and faint proms not over processed and light and fluffy :bow
