Improved position with the 5-times larger focal length instrument
(MASTER-Tunka):
06 00 10.03 +14 26 12.2

Image scale is 1.84"/pixel, and within 0.6" the new object is
identical to the blue star USNO-B1.0 1044-0081025 (06 00 10.048 +14 26
12.76 B1=19.35 R1=19.88 B2=20.02 R2=20.39 I=17.85). It is likely a
dwarf nova of SU UMa type.

Outburst is very young! Nothing was there on MASTER-Tunka images of
2014 Mar. 03.574 UT, two nights before the discovery by H. Nishimura.
The object was not present on the sum of five 60-sec unfiltered
exposures to the limiting magnitude 18.5. Comparison of Mar. 03 and 05
MASTER-Tunka images is posted at
