This Nova is changing rather fast.

Interesting object.

I agree, it will be interesting to see if it gets brighter again.

 

Last night (23/8/20) I had an estimate of 12.2mv at 21:30 UTC. Its clear again tonight and the sun will be set soon, so it shall be my first target of the session.

I've been observing N Cas 2020 on an almost every day and it's proving to be most interesting.

N Cas continues to be an interesting, active, Nova.

The undulating light curve of this nova is fascinating. Has anyone seen an explanation from the experts to account for its behaviour?

 

I went out and photographed the nova for a second time on the evening of Sept 1 and measured its magnitude at 12.9.

 

I have attached a PANSTARRS image on which I have located the progenitor star which has an i mag of ~21.3.

 

The second image is the PANSTARRS image with my plate-solved image overlayed on top.

Nova Cas 2020, (now V1391 CAS) appears to have brightened since my last observation.

 

I had an estimate of <12.6mv on the 8th September, and last night (13th) I made an estimate of 12.2mv.

 

Looks like its on the rise again?.

Looking at AAVSO reports for last two days,

Nova Cas 2020  is indeed brightening  slowly.

Unfortunately KMA Observatory is for the last two days under hazy

 clouds ...........

 

Best observing

I've not been able to recently observe N Cas 2020 (V1319 Cas) because on continuing bad weather. frown.gif

My estimates of V1391 CAS over the last few nights, (the 17th, 18th and 19th) have seen it staying around 12.3mv.

 

Wonder how long it will stay visible.

Rich - last I read, V1391 Cas appears to be an Fe (iron) type nova. These are often characterized by very protracted maxima lasting many months with only an overall very slow, highly irregular decline. These maxima sometimes end in an abrupt fall  amounting to a number of magnitudes, only to recover almost fully weeks later. They subsequently fade slowly and quite steadily back to minimum thereafter.

KMA,

 

I used a 8" f/2.8 Newtonian with a ATIK 383L+ camera.

Exposure time: 120 seconds.

 

Taken from Germany, 30 km south of Stuttgart.

Thanks for info, really amazing sharpness.

Makes me wonder how non stellar object will look like....

(comet for example).

My last three observations of Nova Cas 2020 did not

show any brightening,  magnitude reported  was  12.8mvis.

But one never knows ......

Best wishes for clear sky

KMA

Hi,

 

Yes I read that myself on the BAAVSS website. I'm sure it will fade below the magnitude limit of my 8" SCT before long.

 

Last nights estimate of V1391 CAS was 12.4mv.

 

Cheers,

 

Rich.
