Hello, I just observed ( 20.45 UT ) it again and had it visually at 5.1. This is also confirmed by photometry.

That is 1.4 magnitude brighter in 24 hours. Keep on watching it!

I have made a AAVSO chart for those who want to use it.

No chance here - clouded out and heavy rain due overnight. Maybe some clear spells tomorrow evening.

Thanks for the chart Hubert - very helpful.

Shot taken at 2306UT August 15th, I estimate it now at magnitude 4.8, it's still rising and easy to see naked eye now.

I am at the eyepiece right now. It is brighter than the 4.8 mag in the finder fog and fainter than the 3.5 in the finder fog. I would estimate magnitude 4.5.

Nova is noticeably brighter than last evening. I can't estimate magnitude worth a damn, but I can say with certainty that it is much brighter than last evening. Blessed with two more clear nights coming up!!

First view of Nova Del 2013 tonight, Aug 15, 2013 9:20 pm EDT , August 16, 2013 1:20 UT using 10 x 50 binoculars.

Sky conditions were good, some patches of high altitude clouds around. The 9 day old moon was hidden it trees from my view.

Used stars on AAVSO Chart 12508BUL for magnitude estimate. The Nova was found using charts with a greater FOV, then positive ID using the AAVSO Chart and one from software Guide 8.

Placed Nova DEL 2013 at magnitude 4.7. Without the use of binoculars I could see the Nova and the two 4.8 magnitude stars directly after fully dark adapted. The Nova was brighter than the 4.8 magnitude stars.

I just came in from observing N Del 2013 with my 12x63 bins. Using comp stars 38 and 48 I estimated this nova at mag 4.6.

Barely visible to the naked eye here in red skies, but that's probably due to the moon and neighbor's yard lights. I think I saw it with my 6", but I'm still having trouble distinguishing it from the other stars in the eyepiece. I know it's just my inexperience, but I'd love to know conclusively whether it's the star I think it is. Hopefully once it's brighter that'll help.

Can see it here with naked eye between clouds in an "orange" zone. I took this a few minutes ago - T2i 28mm f/2.8 1600 1m cropped and stretched. (In the original you can see M27.) --Keith

Ditto with my 7 x 50 binos compared with HIP 101867, the 4.8 mag. Just a hair brighter.

After taking images and doing some crude astrometrics, I find it at mag 4.40 @ 8:02 UT . It is brighter than 11-Delta Delphini. If you can see the rhombus in Delphinus at your location, you should now see the nova.

Joe.

This is certainly one of the brightest nova's we've seen in years.

Here is my contribution, a 150 second exposure using a 15 cm f/7.3 refractor (Takahashi TOA-150) equipped with an SBIG STL-11000M:

There appears to be a tiny planetary nebula at about the 8 o'clock position, though I haven't had time to identify it yet.
