Stu Posted April 5, 2021 Share Posted April 5, 2021 Saw it again in the 12” dob this evening. Still seems to be maintaining brightness quite well. 4 Link to comment Share on other sites More sharing options...
JeremyS Posted April 5, 2021 Author Share Posted April 5, 2021 (edited) Yes, pretty much the same brightness as last night, @Stu Edited April 5, 2021 by JeremyS Link to comment Share on other sites More sharing options...
Mark at Beaufort Posted April 5, 2021 Share Posted April 5, 2021 Decided to use the Heritage 130p as a quick grab and go. Using a 9x50 finder scope went straight to M52. Used a SvBony 10 to 30 zoom and located the Nova. Estimated at around mag 8. Seemed the same as 2 nights ago. 1 Link to comment Share on other sites More sharing options...
John Posted April 5, 2021 Share Posted April 5, 2021 Tonight I observed the nova with 11x70 binoculars. It looked around the same brightness that it has for the past few nights. With the more transparent skies this evening M52 showed quite nicely with the binoculars. Link to comment Share on other sites More sharing options...
Stu Posted April 6, 2021 Share Posted April 6, 2021 A couple more shots from me. The first shows the brightness difference to SAO610 a bit better, and the second catches M52. 2 Link to comment Share on other sites More sharing options...
Stardaze Posted April 6, 2021 Share Posted April 6, 2021 The first is how it looked in my binoculars last night @Stu 1 Link to comment Share on other sites More sharing options...
Spile Posted April 6, 2021 Share Posted April 6, 2021 I can't stop seeing that "W". It is their such a thing as an eyeworm? Link to comment Share on other sites More sharing options...
lunator Posted April 6, 2021 Share Posted April 6, 2021 Had another look tonight. It seems to be holding it's brightness. I thought it looked a tad dimmer at first but not entirely sure. Cheers Ian 1 Link to comment Share on other sites More sharing options...
Pid Posted April 8, 2021 Share Posted April 8, 2021 I imaged this a few weeks ago 4 Link to comment Share on other sites More sharing options...
Paul M Posted April 9, 2021 Share Posted April 9, 2021 My first look for a few days. 30 x 30 sec stacked in ASTAP. Photometry (such as it is in my hands) gives a magnitude of 8.42, holding up nicely. I was surprised to see it still outshining it's neighbour. 4 Link to comment Share on other sites More sharing options...
John Posted April 14, 2021 Share Posted April 14, 2021 Just had another look at this nova. Still looking around magnitude 8.0 or thereabouts. 2 Link to comment Share on other sites More sharing options...

Had it about that last night John. Not checked tonight yet. This one is certainly hanging around 👍🏻 2 Link to comment Share on other sites More sharing options...
laudropb Posted April 14, 2021 Share Posted April 14, 2021 Do we know if this a classic nova Jeremy involving a white dwarf and a close companion main sequence star ? Link to comment Share on other sites More sharing options...
IB20 Posted April 14, 2021 Share Posted April 14, 2021 Some very nice conditions tonight, got the nova in the 15x bins again and see it between mag 7.8 HD220770 and mag 8.1 HD220138. 2 Link to comment Share on other sites More sharing options...

Stu Posted April 14, 2021 Share Posted April 14, 2021 I managed an image through the Genesis tonight at x16. Quite nice to see it in a wider context, similar to a binocular field really, 5 degrees. 5 Link to comment Share on other sites More sharing options...

I also wonder if this one will result in a nova remnant ? I'm probably over-simplifying a complex process Edited April 15, 2021 by John 2 Link to comment Share on other sites More sharing options...

I'm probably over-simplifying a complex process During the eruption the spectrum will be dominated by the hot accretion disc rather than the stars. Need a quiescent spectrum to get the stars. even that can be tricky The nova eruption certainly blows off gas into space so there will be a remnant shell. Might take a while to become large enough to be visible on large pro scopes, if at all 1 1 Link to comment Share on other sites More sharing options...
IB20 Posted April 15, 2021 Share Posted April 15, 2021 Not too much difference in mag tonight, I have started to see SAO 20610 next door however which is recorded as mag 9.0 so certainly getting dimmer. 1 Link to comment Share on other sites More sharing options...
Paul M Posted April 22, 2021 Share Posted April 22, 2021 (edited) My first peek in a good while. Poor sky, high cirrus illuminated by the waxing gibous Moon! Surprised I got anything. 22 x 30 sec exposures, live stacked in ASTAP. Photometry by my hand reports a magnitude of 9.1 but there looks to be vistually no difference between now and my last image. Edit: Here is a more fully processed version. Still limited by the poor conditions: Edited April 23, 2021 by Paul M 3 Link to comment Share on other sites More sharing options...
JeremyS Posted April 25, 2021 Author Share Posted April 25, 2021 I have just drawn a light curve of the nova until today (Apr 25). It has maintained its brightness very well and is still mag 7.8 to 8.0. Keep watching as it will fade at some point! Data are from the BAA Variable Star Section and the AAVSO databases. The pink horizontal line at the bottom is what is thought to be the nova's quiescent magnitude 6 Link to comment Share on other sites More sharing options...
Pixies Posted April 25, 2021 Share Posted April 25, 2021 Had a peek last night for the first time in a couple of weeks. It looked little different. Happy that my eyes agree with the above! 1 Link to comment Share on other sites More sharing options...
laudropb Posted April 25, 2021 Share Posted April 25, 2021 Had another look last night and still get it to be about 8.3 1 Link to comment Share on other sites More sharing options...
