New Bright SN in Delphinus

[andrew63]

Just had a brief break between scurrying clouds - 11 pm. Same 10x50s. Where yesterday about this time i could not detect a difference between the nova and 29 Vul it was certainly less bright tonight, but still brighter than Eta Sagitta. Conditions were not great and had about a minute only, but to me just barely under 5th mag. Still quite bright and not sure what the prediction should be. Pleased to see it again however brief !

Agreed, we had scuttling clouds. Managed to show it to a friend using 15x70's, could do with some

clear skies,Nick.

[Andrew*]

It was an easy spot in 10.5x45 binoculars last night and definitely between n Sge and 29 Vul in brightness.

At the same time I realised what a beautiful colour gamma sagittae is!

[cotterless45]

Yep, even pointed out to a friend who'd never looked at the sky that this was indeed a "new " star.

Looking clear here tonight for another look. Be interesting to see the change in brightness

Looks like the tail-off in magnitude has levelled off a bit.

[Mark at Beaufort]

Thanks for that Luke. Hopefully, it will stay clear tonight to enable a view of the Nova and to estimate its magnitude against nearby stars. At the moment I have 70% cloud.

Just had another look 10.45 with 10x50s and compared to my reference star Eta Sagitta, the nova appears to be holding in brightness quite well. I estimate it as no fainter than eta - so around 5th mag.

Yep, I'd agree with that. I also just had a look in my binoculars, and I'd say it's only very slightly dimmer than yesterday, so still close in brightness to 29 Vul but significantly brighter than eta Sge. I'd say about m4.9. I felt it had a pale orange tint to it today that I didn't see yesterday but maybe I just didn't notice.

I've just estimated m4.8 based on comparison with 29 Vul. I think we are all in the same ball park

[Mark at Beaufort]

I just posted on another thread. I concluded that the Nova was similar in brightness to 29 Vulpecula at 4.8 mag. It is certainly brighter than Eta Sagitta at 5.05.

Darn, missed this bit of news while in Tuscany. The prediction for tomorrow is clear skies, so I will be hunting it down.

You're supposed to miss it - that's why you're on holiday in Tuscuny

Not when you have all your astro gear with you. Got the nova in the end.

[Mark at Beaufort]

Got the nova in the end.

Michael did you manage to estimate its magnitude or was the Moon too bright?

Mark

[michael.h.f.wilkinson]

I did. On the night of August 19 I estimated it at 5.1. I estimated it again the next night and it was about the same. Moonlight does not affect brightness estimation of such bright objects, especially with big binoculars

[nitram100]

Is it yellow in appearance? I think I have found it in my bins but hard to tell!

[Andrew*]

Yes,I found it to have a slight warn tone...

[nitram100]

Awesome, I think I found it then. Gonna get the scope out and try and confirm it. Will locate NGC 6905 first I think. Thanks.

[Mark at Beaufort]

I viewed it last night and it has become fainter. I compared it last night with HIP 100754 which has a mag of 5.65. I would say based on my visual observation last night its in the region of 5.7.

Mark

[michael.h.f.wilkinson]

Interesting. It was cloudy last night, but maybe I can have a look at it this evening

[Stu]

It does seem to be a strange one. When I checked it visually a few days ago, it looked just slightly brighter than HR 7811 so I put it at around mag 5.5. I saw a photo taken at a similar time and it looked quite a bit brighter than HR7811 so I would have put it nearer 5.2 ish based on that.

Cloudy last night too do I haven't seen it for a few days. Will be interesting to pick it up again.

Drifting cloud last night Thursday Aug 22 after dusk but got a quick shot via piggybacked 1100d and est mag at m5.5 against circled star and Sloan DSS. Perhaps more importantly [for me!] my 5th spectrum profile within a week as the nova fades - my best early nova sequence in over a decade of nova spectra imaging

[michael.h.f.wilkinson]

Congrats Nytecam, that is a very interesting series of spectra, moving from mainly thermal continuum radiation, to more an more line emission from ionized gas.

Here's last night's raw shot
