[vsnet-outburst 25951] M31N 2008-12a: OUTBURST!

[Tonny Vanmunster tonny.vanmunster@gmail.com via vsnet-outburst]

All,


Further to the below, I just had a clear break over CBA Belgium Observatory and I managed to obtain additional unfiltered CCD images, this time using my 0.40-m f/10.0 telescope. I stacked 8 * 120s images, and M31N 2008-12a is now clearly visible. See screenshot below, representing the stacked image from Oct 31.12 UT.

 

Have to get some sleep now, but I will try to do some photometry tomorrow. Rough estimate from below stacked image: mag 19.6 (CV).


Best regards

Tonny

Subject: (cba:chat) M31N 2008-12a: possible outburst ??

 

Dear all,

 

This requires confirmation, but it might be that M31N 2008-12a is in outburst. I have two sets of images of this evening (2020, Oct 30/31) on which there's a suspected object at the location of M31N 2008-12a. The first set of images consists of 3 * 180s unfiltered exposures centered around Oct 30.86 UT. The second set of images consists of 6 * 180s unfiltered exposures centered around Oct 31.07 UT. All images were obtained at CBA Extremadura Observatory using a 0.40-m f/10.0 telescope and SX-46 CCD camera.

 

All images were impacted by the strong moonlight, so as mentioned before, this needs confirmation. In particular, the first (stacked) image set is highly unsecure.

 

Below are the two screenshots of the stacked images. The left one is Oct 30.86 UT, the right one is Oct 31.07 (suspected object seems to have brightened)

 

Best regards
Tonny
