The Sun re-appeared today!
AR 2729 is a small sunspot about to disappear.
Seemed like nothing happening on GONG today, but on closer inspection there was quite a large but very faint prominence.
So, grabbed an image in a 20 second gap in the rain and cloud:
Haven’t seen the sun for a while, but it did make a brief appearance today. Not much happening, but a couple of pleasing prominences.
Although small, AR 2727 is a nice feature in Ha.
Well – – –
How about this?
A 60mm double-stack for £749!
This is the most impressive prominence that I have seen for a while!
The prominence changed quite rapidly as you can see from the times, and from this animation (the earlier prominence image is a bit fuzzy because the Sun was VERY low at the time!):

Yesterday’s prominences have developed further with the added bonus of spot AR2726. Here are today’s Ha solar images including yesterday’s and the day before’s prominences for comparison.
“A NEW SUNSPOT: Breaking a strong of 24 spotless days, a new sunspot is growing near the center of the solar disk. Here it is. Amateur astronomers with backyard solar telescopes are encouraged to monitor its development. After all, sunspot genesis is rare during solar minimum.”
Yesterday’s prominences have developed nicely.
