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.

As of a few minutes ago, it’s back down to 16.1 in V again.

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
Ian.

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.

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

Hi all,

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

Cheers
Ian.

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

Here are my measurements from a few minutes ago in Spain.

Average of 15 V images = 12.51

Hi all,

Eight consecutive nights from my C11 in Spain shown here – the graceful decline continues…

Hi all,

Here’s an update on SS Cygni. I’ve been intensely monitoring the star for the last two outbursts and have made nearly 7,000 photometric measurements in the R and V bands in that time. It’s noticeable how variable the magnitude is especially during the dim portion of the cycle pre-outburst. Also, two very different widths of outburst.

See attached light curve from the photometry database.

Cheers
Ian.

I’ve uploaded results from last night. Now slipping back to nearly mag 18 in V again.
