There's more on Nova Cygni 2014 at these URLs:

http://www.astronomy...hines-in-cygnus

http://www.universet...pops-in-cygnus/

Its magnitude is 10.9 and it coordinates are 20h21m43s right ascension and 31°03'29" declination.

There's also a nova in Scorpius.

I believe the AAVSO Alert Notice 500 also mentions a PNV in Scorpio.

Here is an image on Nova Cyg 2014 I took last night useing the Slooh high mag camera. I'd estimated the nova at mag 10.7.

10.7 sounds good, similar to the recent SN but continuous cloud here:(

Now Nova Scorpii 2014, CBET 3841. I got a shot of it 27 Mar 2014, 15:40 UT, when it was ~11.6V by my estimate. Appeared reddened.

Cheers -

Well done Rich and Rob with your respective nova Cyg and nova Sco images. :bow:

My shot of Nova Cyg 2014 from just after midnight this morning with the nova just 12deg high in the London light-dome had to be a brief 8s exposure. My nova est = m10.6; stars to mag 16 recorded. Used my new 'high speed' SX Lodestar-Mx2 CCD camera + LodestarLive capture s/ware. :grin:

This thread has been surprisingly quite for the past 6 week, considering that Nova Cyg 2014 is a most unusual object and entertaining object to watch.

This nova is a member of the slow nova class that show prolonged maxima and it has remained near its initial brightness since it peaked weeks ago. Together with that, it is also one of those slow novae that display dramatic random fluctuations over the range of one or two magnitudes in the course of about a week's time, making it very interesting to follow.

Currently Nova Cyg is around magnitude 10.5 . I would, however, suggest those interested in accurately locating this star acquire a chart presenting a much broader field for finding the star than the photo that was posted here. You can choose the field's scale of your desire using the Variable Star Plotter (chart making) feature on the AAVSO's website. It will also include comparison star magnitudes to facilitate estimating the nova's brightness if you so desire.

My last observations of N Cyg 2014 and N Del 2013 were mags 10.6 and 12.6 both observatios were made on 5/28.

My sole shot for tonight [2014 July 16] after dusk with intermittent cloud and first for 3 months - the nova seems to be holding its earlier mag :o

Thanks for the image. My observations have also shown that this nova is fadeing quite slowly.

Indeed, this object is proving to be a wonderfully active slow nova, showing night-to-night fluctuations in its brightness that currently carries it between magnitude 10.5 and 12.0 visually. It should prove interesting to see just how long it can hold its brightness before the long slide back to obscurity commences. Occasionally some of these slow novae will hang near maximum light for a few years!

The Light Curve for Nova Cygnus has been quite active.

Weather has been bad for so long that I wasn't able to get an image of the Nova until last night.

Photo attached.

Excellent image. This has been a very active nova.
