Today I have checked this transient on the photographic plates from
Moscow collection stored at SAI MSU. Position of MASTER OT ​J081443.89
+125459.7 = SDSS J081443.89+125500.0 = GALEX J081443.8+125459 falls
into the 10x10 degree field centered at 12 Cnc. There are 73 plates of
this area in the time interval from 1988 to 1994. The oldest plate was
taken on 1988 Nov. 18/19, the latest one - 1994 Dec. 05/06. The yearly
coverage is varying with 14 plates from 1989, 36 from 1990, 14 from
1991, 1 from 1998, 1992, 1993 and 6 from 1994. The star is below the
plate limit on all images. Typical sensitivity of Moscow plates with
30-min exposures is B=16.5-17.0.
