This is my first variable star measurement since last March. This is largely due to me having problems with Sciatica. I had keyhole surgery on my back at the end of November and am finally ready to continue looking at these fascinating objects. I thought it wise to tackle a familiar object first. It is amazing what one forgets after a lapse, e.g. I initially forgot to turn the camera cooling on and twice had to refer to my own tutorial to use the software!

Nice to see you back outside Dave,
The bit about following your own tutorial made me chuckle.

V799 Aug has a really interesting light curve (I've not seen anything quite as similar either) - graph looks great.

Sorry to hear about your back troubles - hopefully you're back on the road to good health now!

And also proven the benefit of good documentation! 😂

Great to hear your back surgery has been successful Dave, backs really are very poorly designed bits of kit aren't they?

I confess I had no idea that stars could vary over such short time frames, that's a really interesting curve. Glad the tutorial was helpful 😉

Many thanks Graeme. My problems are all due to getting old 🙁 .

By the way, are you by any chance going to the BAA Winchester weekend or the VSS meeting in Northampton on 9 May?

Thanks Stu. I didn't realise I had a back problem because the pain was in the legs. Hopefully all will be well before long.

There is a whole group of stars, HADS stars (High Amplitude Delta Scuti stars), with these short time periods. It does seem a bit mind boggling that such large objects can be oscillating in and out at such a frequency. This particular star seems to have more than one frequency of resonance.

Hadn't even thought about either to be honest - barely thought beyond Feb at the moment! I'd like to be able to make it along to one - the VSS one sounds interesting, but it's in the cricket season and that's Saturdays tied up for me as I play in the league.... 😕

You could come to the VSS day if "Rain stops play" 😀

It'd have to be biblical on the Friday to give me chance! Lost count of the Saturdays wasted waiting for umpires to call the thing off (usually after 2-3hrs of being sat around!) :lol:
