Stu Posted May 12, 2021 Share Posted May 12, 2021 Just wondering if we could put together an SGL light curve for it? If people post up dates and their brightness estimates I could graph them to see what we get? 1 Link to comment Share on other sites More sharing options...
Davey-T Posted May 12, 2021 Share Posted May 12, 2021 Haven't even managed to image it yet where it's buried in light pollution 😧 Dave Link to comment Share on other sites More sharing options...

My estimates are: Brightish, same, same, same, bit fainter, bit brighter and most recently; WOW! Don't have any dates. 🤣 More a swerve than a curve... 2 Link to comment Share on other sites More sharing options...

Stu Posted May 12, 2021 Share Posted May 12, 2021 I’ll run through this thread and put together all the obs from it and see what we get. 1 Link to comment Share on other sites More sharing options...
Stu Posted May 12, 2021 Share Posted May 12, 2021 Here you go, a bit of SGL Citizen Science for you 👍👍. Done as a line and a scatter graph, scatter probably better I reckon. Will keep adding from this thread. If anyone else has any past data not already posted, please put it up. I’m taking a few liberties where people have said ‘a bit brighter than’ etc but it gives a reasonable curve I think. Looks like either the weather was bad or we lost interest in the middle bits! 🤣 6 2 Link to comment Share on other sites More sharing options...

Stu Posted May 13, 2021 Share Posted May 13, 2021 @PeterW and I concurred that the nova is at mag 5.5 tonight, basically similar brightness to HR8894. Any other viewings tonight? 2 Link to comment Share on other sites More sharing options...

JeremyS Posted May 14, 2021 Author Share Posted May 14, 2021 Here's a plot from the BAA Variable Star Section database. Looks like it is past the peak, BUT this type of nova might have a second (or third) peak, Keep watching! 1 3 Link to comment Share on other sites More sharing options...
Stu Posted May 14, 2021 Share Posted May 14, 2021 Thanks @JeremyS. This is where I’ve got to with the SGL version. We seem to have more of a dip before the recent rise than the BAA one, but interesting none the less. 4 1 Link to comment Share on other sites More sharing options...
Captain Scarlet Posted May 14, 2021 Share Posted May 14, 2021 I had it at an estimated 5.6 last night, 2322. A smudge dimmer IMO than HR8894 2 Link to comment Share on other sites More sharing options...

Last night was weird. I viewed in binoculars and felt similar to you, that it was a touch dimmer than HR8894. Then through a scope I couldn’t convince myself I could see any difference. Still not sure, but I logged myself at 5.5. Would be interest to see what a proper measurement comes out at. 2 Link to comment Share on other sites More sharing options...

You can other data here: https://app.aavso.org/webobs/results/?star=000-BNX-642&num_results=200 as usual some scatter in estimates as people have different eye sensitivity, observing conditions etc. You will see some CCD V measures in there too. These have tended to be a bit fainter than visual. The nova is reddish (you can see Blue filtered measurements in the BAA VSS plot above come out fainter) 3 1 Link to comment Share on other sites More sharing options...

April was fantastic, but May has been pretty disappointing. 1 Link to comment Share on other sites More sharing options...

Grab and go will be order of the day (or night) I reckon! Link to comment Share on other sites More sharing options...
