Never rains but it pours! Koichi Nishiyama, Kurume,Japan and Fujio Kabashima, Miyaki,Japan, have discovered a new possible nova in Scorpius, mag 11.1, on 03 June 2013. The object has several confirmations but needs a spectrum to confirm it as a nova (or not!). Robin? ;)

Christian Buil beat me to it :-) looks like a classical nova

Hi Robin - did a quick check and this one and it's theoretically ~2 deg above my southern meridian horizon and actually invisible in trees and bushes :o How's it for you 'tup north :question:

Clear tonight and finally got an image of the nova. Just! The nova is bright in infrared which is not good news if you've got an unmodded DSLR. Very faint, not like the bright response of CCDs. I wouldn't have got the faintest trace of this one in my normal 55mm nova search fields.

Cheers -

Hi Maurice,

I did not bother to check after I saw Christian had got it, but no, it doesn't get above the horizon here though so I would not have got it anyway. (It was pretty impressive for Christian to get a decent spectrum of this fairly faint object which would have been at low elevation even from Southern France)

Cheers
Robin

Yes - remarkable result for Christian @ 43.6N [Toulouse] eg only 8 degs better than me so still very low in his sky :o

Based on this image I estimated the magnitude of N Sco 2013 at 13.4.

Took this image of N Sco 2013 on the 15th. I'd estimate its magnitude at 14.0.

Took this image of N Sco 2013 on 6/26. N Sco continues to fade, estimated mag 15.7.

Most likely my last image of N Sco 2013. In red light I'd estimate this nova has faded to at least 17th mag. The AAVSO LCG shows the nova at about mag 17.5.

On 8/9/13 I once again imaged N Sco 2013 with the Slooh Remote Observatory. N Sco is now extremely faint but I was able to ID it. I can only take an educated guess as to its magnitude but I would say 18th mag possibly fainter.
