Hi all,

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.

Not sure if this is of any significance?

Cheers
Ian.

Hi Gary,

I got it last night from Spain in R and V. See attached.

R = 12.97, V = 13.57 (average of 19 measurements)

Cheers
Ian.

Hopefully someone else caught it last night – Ian?

Hi Magnus,

Unfortunately not. The weather has been poor here (I can’t get it from Spain anymore). Looking promising for tomorrow (Monday) evening….

Cheers
Ian.

Hi all,

Just finished a quick session here and get 16.6 V over 3 images. Data in the dB.

Cheers
Ian.

[Mr Ian David Sharp]

Hi Magnus,

Yes, 14.01 in V at this moment. (average of 12 images).

Data uploaded.

Cheers
Ian.

Another re-brightening in progress – I have it at 13.65 with Clear filter just now.

Yes, I agree, I’m getting an average of 13.66 in V over 11 measurements.

Cheers
Ian.

Hi all,

Poor, hazy conditions from here last night, but I managed 8 images and they are swinging around an average of 15.07 in V.

Cheers

Unless there is something seriously off with my routine, I captured it at around magnitude 13 yesterday. Here is a series designed for mag 16 (Clear filter, 5 min exposures).

That’s amazing Magnus!

Poor weather here last night, but I reckon there’s a decent chance I’ll be able to get it again tonight.

Cheers
Ian.

[Mr Ian David Sharp]

Hi all,

I managed 26 x 180s images last night – see attached. I concur with Gary and Magnus that it is down at about mag. 16.2 in V.

Cheers
Ian.

Clouds rolled in here near Selsey about two hours before the start.

I managed these video clips through cloud gaps and haze:

Hi all,

My recent measurements in V show a very linear looking fade. I just added last night’s measurements.

Cheers
Ian

Hi all,

A real drop in brightness, much fainter tonight. Here are 50 more measurements from here in the UK.

Cheers

Hi all,

I managed 39, 120s exposures last night from here in the South of the UK. The sky was very milky due to the Canadian wildfires, so the quality was not as I had hoped. Graph attached and data in BAA and AAVSO databases.

Cheers
Ian.

Another update, nearly 10,000 brightness measurements in the last two outbursts.

There are some fascinating details in the variability within the daily bursts of measurements. I need to analyse them further to see what they contain.

Cheers
Ian
