Very nice photometry, Ian.
Looks like a pre-eclipse hump (due to accretion hot spot).

Thanks Jeremy,

I’ll keep monitoring it and get longer and longer runs on it as we get our nights back!

Hi all,

A better image from me. This time 36 x 90s with L filter.

https://britastro.org/observations/observation.php?id=20250728_122425_2b3fb6faab2f3379

I measured the V mag to be 17.5 +/-0.1 using an aperture radius of 12 pixels (0.48 “/pix) with APASS V mag band.

Yes, very sad. A really helpful chap.

Hi Grant,

Yes, I wrote an ASCOM Alpaca driver for my dome 2 or 3 years ago. I believe it was the first ever Alpaca dome driver. Works like a charm.

However, it was written in Python. It runs on a Raspberry Pi.

Sad news!

I’ve known Storm since I was a young teenager in the SDAS (South Downs Astro Soc.) in the early 70’s.

Hi all,

It seems SU UMa has brightened again. Last night was around 12.75 in V. See attached.

Cheers
Ian.

Marvellous! Thanks Jeremy.

[Mr Ian David Sharp]

Yes, this is typical and a diagonal is normally required. All my modern refractors are the same. It allows for lots of backfocus for Cameras, filter wheels and OAGs.

Thanks Gary,

I’ve uploaded my R, V and B results from last night – it seems to have steadied. I’ll continue to observe it when I can and my data is always in the BAA database if it’s needed.

Cheers
Ian.

Hi all,

There’s a small brightening of OJ 287 going on. Not sure if it will be significant.

Cheers
Ian.

Let me know if I can help, David.

I enjoyed the Mars encounter.

Hi all,

I managed a decent run last night from Spain and concur with the ~0.067 day superhumps. See attached.

Cheers

Ian: I’ll be uploading my CCD observations to the BAAVSS database shortly. The software will detect that this is a new object, and will create a new file with the name I upload it with – which is GOTO065054.49+593624.51 I can’t see any alias in VSX, so it will be this long winded nonsense I’m afraid.

Thanks Gary, I’ve successfully uploaded my data now.

Cheers

Hi all,

I set my C11 in Spain to image it for a couple of hours early this morning (6th Oct : JD 2460589.588866 – 2460589.697257) and got 132 measurements in an L filter. I used AAVSO chart X38448OQ and V magnitudes to get the attached. Average Vmag was 13.33 and there seems to be a gentle fade (the check star looks flat).

See attached for light curves and also the FOV with comp stars from AstroArt8.

Andy – are we going to add this to our BAA database? I have uploaded to the AAVSO db.

Cheers
Ian.

Well done Andy!

Marvellous news.

I’ve been monitoring V615 Vul in R, V and B since early August and I’ve noticed in the last 5 or since days that the R and V mags have closed right up. See attached.

Hi all,

I must apologise. I have been wrongly using the B mags for my R filters since 5th September! I am in the process of replacing them in the database!

Hi all,

I’ve been continuing my intensive monitoring of SS Cyg and I can report another outburst has started. See attached with last night’s results.

Cheers

Hi Gary,

A tad brighter last night, see attached.

R = 12.3, V = 12.9

Cheers
Ian.
