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, an from this animation:

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.
Venus this morning from the window-sill.
Main picture with Canon SX610HS hand-held.
Inset with 80mm f/5 refractor + 2X X2 barlows + PD camera.
“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.
Here are today’s Ha solar images including yesterday’s prominences for comparison.
Very little happening on the Sun, but a moderately interesting prominence with some detached plasma.
A reasonable prominence today.
After having endured a certain amount of leg-pulling at the trustees meeting last night concerning widow-sills and double glazing, lo and behold, Orion was in view from the aforementioned window-sill after I got home.
This month’s Deep Sky Tour in the Sky at Night mag. was all about objects in Orion’s sword, so despite a prominent moon, I acquired some images.
Starting with NGC1981, the “crocodile” cluster and NGC 1977
NGC 1977 is in fact the “Running man” nebula, so the next image was a longer exposure and processed to bring out the nebulosity:
Then on to NGC 1980, together with M42, just to orient yourselves.
Again this was then processed to bring out more of M42’s nebulosity:
The next 2 images are NGC 1980 without the focal reducer to bring out the rather nice double Struve 747
Although I didn’t try to image M42 and M43, here is a reprocessed one from last winter with the same set-up to complete the “set”.
Curiously, in the same issue of the magazine there is an article about the best winter clothing for observing – it might be interesting to note that I was in my pyjamas during all this – – – !
(BUT I am NOT going to attempt to demonstrate this at the next Science Day!)
After days of nothing, some small but interesting prominences today.
Again, today, I actually prefer the colourised version
