Hi David,
I think that V shape and the right hand wing (on your image) feature have been faintly visible on some unfiltered images since the summer.
Such as here:

and
https://britastro.org/observations/observation.php?id=20221129_230930_656c96e63f3df518Was it absent in your similarly exposed Rc filtered images from earlier in the year? The nebula is heavily reddened, so you might well see changes before those of us working unfiltered noticed them.
Do you still measure the nebulosity brightness at all? What does that curve say?
Would be nice for this or McNeil’s to reappear at last. Looked at Thomme’s last night and can’t see much change since I started looking at it and McNeil’s is absent with V1647 Orionis in the 19.5-20.5 mag range when skies are clear enough to detect it.
Happy Solstice!

From Wiltshire, at 0630 the Sun is about 8.3 degrees below the horizon. TheSkyX still shows 1st and 2nd mag stars visible at that time, but I don’t know how accurate that is.
I think this guarantees cloudy nights for a week…
You probably need to add dancers, a 120bpm backing track, some dry ice, lasers, a conspiracy theory and someone being humiliated to keep social media fans tuned in.
Seems to be working. Looks like thin cloud presently.
There are a couple of small dust patches – as you said – but nothing thats going to detract from a good chunk of the Sun being obscured…
It was fun to watch and some of those observing from the ground did quite well too…

3 tonnes of TNT appears to have made a pretty impressive cloud of debris.
Yep. Dangerous talk as it disagreed with Aristotle AND Scripture!
Galileo got house arrest for more than a decade and banned from publishing…
At -27 theres not much hope from home for me then as my dome blocks everything below -10 and a nearby hill blocks everything below -15.
Damn.
After seeing the pictures from Giovanni, I dug out an old picture….

Ah, excellent. I looked and they appear to have a place holder object name in place, so it looks hopeful.
It could be a lot of fun. It looks like it will be taking a while to get there.
Lovely images. The Belt of Venus is rather beautiful.
I only see it occasionally in the UK. Does it require particularly transparent skies to appear?
On 25minutes worth of frames I am seeing something very dim and (on my frame) at the 7 o’clock position from the 15.7 mag star, but that seems slightly out of position compared to the AAVSO chart. Is that it?
Gary,
I’m on target now and not seeing it – unless its very, very close to the 15.7 star and the two appear merged.
Could it have faded already?

Hi Andy,
Yes, I can imagine everyone would think “Wow! Thats a great opportunity.”, but surely before engaging programmers there must have been some vague plan for how that time would be used?
Not meaning to be awkward, but I’m curious as to what the Council thinking was. 🙂 There is obviously quite a range of possibilities.

Hi Callum,
Oh yes, now you mention it I think I recall seeing that once before. So, that would be used in some way for scheduling one imagines, but scheduling what?
Is the BAA thinking of buying telescope time from a commercial site, buying footprint at a managed facility and setting up their own scope or buying a BAA defined system to be run at the site in question. What sort of operating model are they thinking of?
Similarly, is this intended purely as a recruitment carrot to dangle or would it (if a BAA system) also be available for the sections so its output every year did not consist of entirely of another 2000 narrowband images of M42, M31 and M45.
