Another large-amplitude dwarf nova in Draco was found by Vladimir
Vladimirov in MASTER-Amur data from Mar. 10th. The images were
obtained just 12 minutes after the object discovered by P. Balanutsa!
It has nearly the same outburst magnitude, and it was published in the
same ATel #5974.

There is a faint (~22.5m) blue star at the position of the OT on the
sum of digitized Palomar plates. Color-combined DSS finder chart
There is an UV counterpart GALEX J200904.5+825153 with two entries in
GALEX catalogue with different magnitudes: FUV=18.01, NUV=18.05 and
FUV=18.71, NUV=18.73. The star was probably caught in outburst during
the observations by GALEX.
Outburst amplitude is about 7m! Time-resolved photometry is strongly encouraged.
