[vsnet-alert 13089] Re: DR UMa outburst!

[Tom Krajci]

Initial unfiltered images from Astrokolkhoz (C11, 90 seconds) show an 
object at J2000  13 59 05.77 +55 44 29.49 at approx unfiltered mag 17.

At the SIMBAD coords for DR UMa (13 59 05.4 +55 44 04) approx 25 arcsec 
away...nothing is detectable with a single image (fainter than mag 18?)

This is a faint image for a C11.  I may increase exposure time to 120 
seconds to slightly improve SNR.

I will sit on this target for at least a couple hours....
