Good observing,

I usually 'try' for nova and thanks for that but it only makes 4 degrees altitude on my southern meridian and that's lost due to obstructions so I'll give it a miss

I know what you mean. After plotting the location of this nova I realize it would be difficult to observe from my location. Too many obstructions.

Me too, it does'nt rise from where I am...
The latest is it is at about magnitude 9, so it's fading fast.

I got it! Finally!

After three nights of frustration (clouds, fog, equipment failure, never getting more than 18deg from the horizon down in the light-muck) - I finally captured nine decent frames right at sunrise from my 20D at prime focus on the NexStar 5.
I don't think I've ever worked so hard to get an image for so little return...

Congratulations, at least someone saw it. 
Thanks for the view and clear skies.

Thank you, Rich!
This is one of my favorite images that I've made. It's certainly not the "prettiest", but the challenges I had to overcome really made it special for me. My friend Cinde and I were pouring over the star-charts this evening(the image I posted is just a crop, the full frame is in the same directory that I linked above), and the moment we realized that there was a bright star there that "shouldn't be" - it was really rewarding.
Thanks again for your comment!
Clear Skies,

Congratulations to Alfredo Pereira on his discovery!
I'm clouded out here - I should be able to see it otherwise.

I've had Nova Puppis (V597 Pup) on my short list of things to observe for a couple of weeks, but I've not been able due mainly to weather and because I'm more of an evening observer. I couldn't find many observations of the nova on AAVSO or here on CN so I wasn't sure how bright an object I would be looking for.
I downloaded a mirror-image chart of the area. I'm not experienced as a variable star observer, but I did find it interesting to watch Nova Vulpecula (V458 Vul) get dimmer over several sessions back in August.
At about 2:30 a.m. CST, December 4, at around 20 degrees above the light-polluted southern horizon, I found the field, found a suspected object, and compared it to the reference star magnitudes. It was much dimmer than stars of 10.2 and 10.7, perhaps a bit more difficult than an 11.2 star, but somewhat easier than an 11.5 star. I'd guess 11.4, plus or minus 0.2.
I hadn't studied Jodie's image until after I came inside. (Jodie, your image was helpful for me in transcribing my notes. Thanks!) The image confirmed my suspect star, except that since November 18 it had dimmed with respect to the star directly below it as well as to the pair several arcminutes below it.

An excellant observation. Have you checked the AAVSO Light Curve Generator? You can compare your observation with others on this Nova.
Good luck and clear skies.

Hi HT,
Thanks for the observation and feedback too!
In the sky I have, I suspect anything down approaching Mag 12 would be a reach for me, although some of the really dim stars in my image are Mag 14+. I might have to get out there and see if I can find it again (I've been courting 8P/Tuttle lately). Thanks for the impetus!

Rich and Jodie,
Rich, thank you for the tip: I checked the AAVSO observations from the link (Keith's post) but the most recent one was magnitude 10.9 on December 1.
It's been cloudy most nights recently in SE Texas; I finally got a clear and cold night. So, I observed the Nova for the second time (early morning December 17 CST) and it was looking pretty dim. I'd estimate mag 11.6 now, as it was only averted vision and only half the time as compared to a 11.5 star that was seen at least two-thirds of the time. I wouldn't have found it if I wasn't already familiar with the field.
Jodie, it might be cool to image it to compare with the Nov 18 image. I think you can still pick it up based on last night's magnitude estimate. It's dimming seems to have leveled off some, just a couple of tenths of a magnitude in two weeks. No Tuttle for me yet; I had trees in the way. Tonight I had clouds again.

Thanks for the feedback!
I'm rained in. It broke for a couple hours and I set up the 'scope and just as I was screwing the camera on, the fog rolled in at an insane speed. All I could see of even the moon was a huge white glow. sigh.
I'll keep my eyes open. This nova has been my "elanor".
