Pixies Posted May 31, 2021 Share Posted May 31, 2021 I'll say very close to HD 220167. Mag 7.2 1 Link to comment Share on other sites More sharing options...
Stu Posted May 31, 2021 Share Posted May 31, 2021 I took a few smartphone shots of the nova last night, I was somewhere a bit darker so I had some much better views than normal. 7 Link to comment Share on other sites More sharing options...

Peter I was actually ‘ooop Norf’, well, Bakewell in Derbyshire to be precise. Skies much better than home, it’s so nice to actually be able to see objects like M13 and M27 in the finderscope! Unheard of back home. Even managed M51 in the 4”, twin cores and visible haloes surrounding them, nice. 3 Link to comment Share on other sites More sharing options...
Captain Scarlet Posted May 31, 2021 Share Posted May 31, 2021 (edited) Tonight, for me, with my usual 15x56 Zeiss, impossible to separate in brightness from HD220167, so 7.1-7.2 by my estimation. M Edited May 31, 2021 by Captain Magenta 2 Link to comment Share on other sites More sharing options...

M Had a quick look with my 12 inch dob earlier. Same for estimate for me. It's still very much "with us" isn't it ?

Davey-T Posted June 1, 2021 Share Posted June 1, 2021 Hoping to see it shortly once it drags itself clear of the LP. Dave 2 Link to comment Share on other sites More sharing options...
JeremyS Posted June 1, 2021 Author Share Posted June 1, 2021 The BAA VSS light curve indicates the brightening trend of the nova has continued over the last week. May 31.208 7.24 TG (Gary Poyner) May 31.995 7.1 vis (Paul Abel) 3 Link to comment Share on other sites More sharing options...
Stu Posted June 1, 2021 Share Posted June 1, 2021 SGL version here. My trend line is looking fairly useless, so I will likely abandon it in favour of just the scatter graph. I don’t think the ‘join the dots’ line helps much? 6 Link to comment Share on other sites More sharing options...
PeterW Posted June 1, 2021 Share Posted June 1, 2021 @Stu you just need to use a higher order polynomial fit….. always “works” with enough terms….. Peter Link to comment Share on other sites More sharing options...

PeterW Posted June 1, 2021 Share Posted June 1, 2021 No fair… maybe need some nurbs or Mr Chebyshev…. Plotting the whole light curve, looks like some subtle little lumps may have occurred, regular measurements are definitely important.

Fewer people and poor weather I guess. Link to comment Share on other sites More sharing options...

Also the very bright summer sky is making it more difficult to estimate magnitude, although I did get a reasonable value of 7.1 last night. 1 1 Link to comment Share on other sites More sharing options...

Plot looks good @Stu👍🏻 Shows Rhea recent brightening trend. I prefer your third plot without lines. 1 Link to comment Share on other sites More sharing options...
John Posted June 4, 2021 Share Posted June 4, 2021 Clear night and another brightness estimate data point from me, this time using a 102mm refractor at 28x magnification. I feel that the nova is really quite close to the brightness of the star HD 220057 which is magnitude 6.9. So I'd say mag 7.0 for the nova ? 2 1 Link to comment Share on other sites More sharing options...
Pixies Posted June 5, 2021 Share Posted June 5, 2021 2am, with new 80mm Vixen and x35. I'd say it's as bright as HD 220057, so mag 6.9 2 1 Link to comment Share on other sites More sharing options...

laudropb Posted June 5, 2021 Share Posted June 5, 2021 Clear sky and good seeing last night. Estimated at mag 7.0 2 1 Link to comment Share on other sites More sharing options...
Captain Scarlet Posted June 5, 2021 Share Posted June 5, 2021 Same brightness to me tonight as HD 220057, making it 6.94-7 I reckon. Zeiss 15x56 bins. Also discovered a top tip. With these fancy eyepieces which have both 2” and 1.25” nose pieces, it really helps to remove the 1.25” end-cap to be able to see things. Cost me about 10 mins tonight 🙄 trying to work out why I couldn’t see anything. 1 7 Link to comment Share on other sites More sharing options...

JeremyS Posted June 6, 2021 Author Share Posted June 6, 2021 Gradual brightening continues. Now brighter that 7.0. 4 Link to comment Share on other sites More sharing options...
John Posted June 6, 2021 Share Posted June 6, 2021 (edited) Clearly the white dwarf is still busy accreting material from it's larger companion. Hopefully I'll get another look this evening. Edited June 6, 2021 by John 1 Link to comment Share on other sites More sharing options...
John Posted June 6, 2021 Share Posted June 6, 2021 100mm refractor at 37.5x. The Nova seems to lie somewhere between the stars HD 220057 and HD 220819 in brightness tonight. Those are listed as magnitude 6.9 and 6.6 respectively so I'll go for magnitude 6.75 for the nova 5 Link to comment Share on other sites More sharing options...
