UZ Boo had faded to 16.66C by last night, so now we’ll be looking for rebrightenings over the next few days.
Gary
Good work Magnus. These are the first Sh I’ve seen during this outburst. Can you continue to follow to see how they develop?
Gary
Steve is a member of one of my societies (Bromsgrove AS). He gave a practical demonstration of his cloud chamber and particle tracks at a monthly meeting several months back. It is very impressive, and great fun to watch. He’s a top speaker too!
Gary
Paul,
Whatever suits you really. The outbursts are so rare that t/s is always welcomed, but if your busy on another project then stick with that.
Gary
Thanks both.
Heavy cloud here in Birmingham, but just secured an image using SLOOH in Tenerife. A quick look at the live view matches your mid 12 estimates. I won’t get the fits file until mid morning tomorrow.
Keep going if you can.
Gary
Good work Ian. So, no superoutburst then. Oh well. Wouldn’t be much fun if we could predict them.
Gary
This Nova now has the offical designation V615 Vul.
I’ve asked Andy to add this to the DB, in addition to N Vul 2024 and PNV J19430751+2100204.
Gary
Good work Ian and Magnus. Amplitude still quite large! I wonder if this will re-brighten?
Is this data merged with the 16.3V companion, or has that been extracted? Just curious.
Gary
I had a short break in clouds last night – 31st (before torrential rain and storms), and made a visual estimate of 10.2 with a 22cm. Might not be my best estimate, as struggling with Covid – and feeling pretty sorry for myself.
Gary
Thank you both Mike and Ian.
That’s an interesting time series Ian. Quite an amplitude of variation during that rapid fade. Don’t have much to compare it with though, so we’ll have to see what happens. The duration of the outburst points to a normal one, but as I mentioned above, this might be a precursor – so if you can, please keep your (digital) eye on it during the next week if possible.
Lovely day here yesterday, but low cloud came over as darkness fell, so only a CCD measure from me…
July 30.0861 16.522C (Slooh 2)
Cheers,
GaryMike,
It was fainter this morning – visual 13.7 on July 29.076. The Slooh image this morning measured at 14.012C on July 29.1063
Here is a cropped gif from the Slooh image you requested.
The quick fade probably suggests a normal outburst, but it might also be a precursor to a superoutburst. UV Per did this many years ago and caught everyone on the hop.

Steve,
You’ll probably find Jeremy Shears article in VSS Circular 200 of interest, as it contains this snippet from the Times and a whole lot more…

Very sad news indeed.
He gave a wonderful talk at the Winchester weekend many years ago (Alfred Curtis lecture) when it was held at King Alfreds college. As a modest collector of star atlases, I was enthralled.
Gary
I measured it at the same magnitude 16.738C one minute after you Stewart (mine was the next job after you in the queue).
Gary
I’ve been following this visually and remotely for a while now.
Image below is from last night (June 24.95 UT), and is a truncated image taken with SLOOH Canary 2 Ultra Wide field 85mm Teleview riding on the main telescope.
Unfiltered magnitude 9.4CV using the BAA T CrB sequence.
