Spot 2712 seems to be vanishing. It isn’t very exciting in white light, but in Ha there are lots of swirly bits. 2711 is also about to vanish. There are a couple of reasonable prominences.

Lunar dome spotting from the window-sill. 26/05/2018
The moon phase, nearly full, wiped out any prospect of DSO observing tonight, but it seemed ideal to do a bit of dome spotting.
Domes tend to be small, and that stretches the poor little window-sill ST80 to the limit.
Anyway, for what its worth here is an image of 3 of the Gruithuisen domes. Mons Gruithuisen, Gruithuisen gamma and Gruithuisen delta. You can tell that they are raised domes as their shadows are reversed to those of craters.
Moon, Jupiter and Noctilucent Clouds 26/05/2018
Just spotted this from the window-sill. (Jupiter is near the centre)
Sun a bit more interesting today – – -23/05/2018
The Sun is a bit more interesting today.
The plage that has been around for a while has now developed into a full-blown, if small, sunspot (2711). (Just to the right of centre)
Spot 2710 has all but disappeared.
Interesting X-shaped prominence on the lower left!
New (tiny!) Sunspot – – – 22/05/2018
All quiet on the prominence front, but there is a new, albeit tiny, sunspot.
Sun 20/05/2018
Not much doing today, but given Andy and Damian’s observations yesterday about evolving prominences, it is interesting to compare what features there are 24 hours on.
Sun today – – – 19/05/2018
Air a bit steadier and the sky clearer today, so the images are better. Since yesterday, the filament has developed and some prominences have appeared on the advancing limb. If you want to compare this with Andy and Damian’s images later today, don’t forget I have flipped and rotated these to match those from GONG and SOHO.

Jupiter
Although I was moderately pleased with my last image of Jupiter, take a look at this!!

Sun-dogs (Parhelia) 18/05/2018
Although they had decayed somewhat when I got this shot from the garden this evening, the sun-dogs still put up a nice display. It is less obvious, but you can also see an upper tangent arc at the top of the picture.
