My estimate was magnitude 5.0 at 0:05 UT Aug 16, with 7x50 binos. To me, at the moment it was just a tad fainter than 29 Vul (4.8). It is brightening quickly!

My estimate at 10:00 PM EDT on 8/15/13 was 4.9, just slightly dimmer than nearby 29 Vul. It was easy to see with averted vision and not too difficult to view directly.

I had it just 5 hours after it's discovery. Brightness is changing very fast! Here is some photometry done on it. It's a great object to observe...

Is there a new AAVSO designation for this Nova? The designation PNV J20233073 2046041 no longer works with the VSP.

"The star PNV J20233073 2046041 cannot be found in our database under that name. "

Thanks

John

You can find it with 'nova del 2013'

Finally spotted it last night with binoculars and the naked eye- it's quite cool to see! I'll keep viewing it as long as it stays visible.

What was the magnitude of this star before it started to brighten?

Consulting the AAVSO's latest plot of submitted data (as of 16h UT Aug 16th); it seems likely now that Nova Del will have surpassed magnitude 4.0 by the time darkness falls in North America tonight. It is most unfortunate that the waxing gibbous moon is at the same time edging toward its least elongation with the nova's position, reducing the spectacle.

Based on the shape of the lightcurve so far, it seems increasingly likely that this object is at least a "relatively slow" nova, making its peak brightness still potentially a day, or perhaps even several(!), in the future.

If true we are looking at the brightest so far this century. For those who had awful Perseid weather this is a nice consolation!

In fact, if Nova Del should indeed surpass magnitude +4.0 this evening, I believe that this would make it the brightest nova easily visible from the Northern Hemisphere in nearly 40 years! However, it is unlikely to beat the record set by 1975's Nova Cyg, which I saw peak at a truly spectacular +1.7 , looking like a second Deneb in the Northern Cross!

Observed the nova last night ( 5:30 UT 8/16/13) and found it's magnitude to be 4.5 . And big difference from the night before.

I remember that one very well. It was very beautifully placed in the Cygnus Milky Way. Saw Nova Del 2013 easily last night with 10x50s thru moderate cloud cover. Tonight should be very clear.
