I had another clear night tonight Fri. Aug. 30, 2013 and took my binoculars to the back yard for another look at the Nova. It has dimmed a now. I would estimate that it was approximately magnitude 6.9 using my 10x50 binoculars at 10:10pm EDT. I think that is 0210 UT Aug. 31, 2013 if I did the math corectly.

I had another really good clear night tonight Tue. Sep. 3, 2013 and took my binoculars to the back yard for what may be close to my last look at the Nova. It has dimmed now to what I would estimate is approximately magnitude 7.2 to 7.4 using my 10x50 binoculars at 09:30pm EDT. It and the magnitude 8.0 star beside it were both averted vision targets. It has certainly been fun following this nova.

I observed Nova Del at 0230 9/04/13 UT (9:30 PM EDT 9/03)with my 12x36 IS II binoculars. Estimated magnitude was 7.2 using nearby comp star 7.1--it's dimmed another whole magnitude since my previous observation 10 days ago. Transparency was good and I could see the nova with direct vision.

Through my 15X70 binoculars tonight, 09/03/13 10:15 PM CDT (03:15 08/04/13 UTC) Nova Del 2013 was still visible with direct vision as was the 8.0 M star to its NNE. It appeared to be about 2X brighter than the 8.0M from my backyard green/blue zone. Seeing was above average and transparency was average.

It was noticeably dimmer than my last ob on 09/01/2013 UTC.

Wow! You do not know how fortunate you are. I have to travel 70 to 80 miles to get to a blue/green zone. My observations, where my home is located, are from a white zone. At best it is in a red zone on the edge of the white zone. :bow: :help:

Here's an animation of 3 sketches I did of Nova Del 2013 over a 20 day period. :)

Luckier than you think Buddy, I'm 5 minutes from blue/gray skies too most of the time. Of course, it doesn't matter when the clouds roll in about 8:00! It's been fun following the Nova, but now I'm on the Colorado Front Range in a white zone. :( By the time I get back, the moon will be shining bright and my skies will look a lot like yours anyway. :lol:

I had another really good clear night tonight Fri. Sep. 6, 2013 and took my binoculars to the back yard for what may be the last look at the Nova with my 10x50 binoculars. It has dimmed now to what I would estimate is approximately 8th magnitude using my binoculars at 09:10pm EDT. It and the magnitude 8.0 star beside it were both about the same magnitude and both were averted vision targets. It has certainly been fun following this nova and I will miss seeing it with the binoculars.

Observed Nova Del at 0245 7 Sept UT with my 12x36 binoculars. Estimated mag is 7.3.

Wow Ed, did I miss it that much? I was having a hard time finding it in my light polluted sky. I thought I could see a single star with averted vision but when I got the star in my sweet averted vision spot they were both visible and looked the same magnitude. I guess I could be wrong because, like I said, I thought I could see a single star at first. You are probably more skilled than me in this, so I would go with your estimate. I will try again tonight if the conditions are good enough.

Buddy,

I did not need averted vision to see the nova or the star just west (above) it. Transparency was very good that night and I don't have any light pollution. Perhaps you had high clouds along with your LP?

I'm no expert and estimating tenths of magnitude visually is tricky and subjective. The nova was definitely brighter than the other star (I'm talking about HIP100536 mag 8.0).

I haven't seen any other mag estimates for 9/7 UT to compare our estimates to. Any around?

Observed Nova Del 0115 11 Sept UT with my 12x36 binoculars. Estimated the mag to be 7.3-7.4--transparency not as good as my last observation and a little moonlight. Fading seems to have slowed to a crawl.

I'm observing the nova as frequently as possible. Did you notice, that it is much more orange/reddish now? Around its maximum it was pure white to my eyes, but now it is definitely different color. BTW, here is the light curve based on my observations:

I haven't notice any color except bluish-white, but I usually don't see color very well. Others have reported bluish-white to start, changing to yellowish and now reddish.

What do the numbers on the X axis of your chart mean?

I called my girlfriend to show her the nice reddish color of nova which was quite obvious to me in my 63mm refractor at 21x. Especially in contrast with nearby V=8.0 magnitude star. But she could not see it neither...

JD on x-axis label stands for Julian Date.

Last night (9.22.13) at 120x it appeared yellowish-orange and brighter than its mag 8.0 neighbor star.

I viewed it last night with my 15x70 binoculars about 12:00 AM CDT (05:00 UTC). I didn't know what to expect as it had been several weeks since I'd seen it, but it was still there. It looked pretty close in magnitude to the 8.0 mag star to its north. It looked cool white from my location. Seeing was average and transparency was good with a waning gibbous moon.

Nytecam, wonderful video, thanks. Somehow I missed your post and found it just now.

I took my 10x50 binoculars out last night, Mon. Sept. 23 2013, 10:15 pm EDT. It was an exceptional night here in town, with a NELM of 4.3 in the constellation of Delphinus. Gamma Delphinus is mag. 4.3 and it was the faintest star in the neighborhood that I could see with averted vision, so it was a great night here at home in my white zone. Try as I might, I could only see one star in the location of the nova. I do not know which star I was seeing, the nova or the 8th magnitude star beside of the nova. I guess that I will have to get out a telescope to follow the nova any futher from my home. :( :bawling:

Tonight I started out with Nova Del 2013 instead of ending with it like last time. I had good looks both through the 15X70 binoculars and the C8. Between 02:00 UCT (9:00 PM CDT) and 2:30 UCT, the seeing and transparency were good with no moon and twilight ending. NELM in the area was better than 4.8 because 29 Vul was direct vision.

With the binoculars, the nova looked almost identical to the 8th mag star and cool white or maybe pale blue. The C8 showed the nova noticeably dimmer than the 8th mag star, but not nearly as dim as any of the 9th mag stars in the FoV. It was nicely framed at 127X and had a golden/yellow color.

I looked at the nova last night with my 10" refl and at 38x no color was noted but at 76x the nova appeared a pale orange color.

This it good news. Somehow I just heard about this and was wondering if I was going to be able to see it. I have 25X100 binos and 10 and 14" scopes so I'm sure I'll see it when I get home from work next week.
