Fainter companion 9.1"arc to northeast, so be careful reporting depths.

Basic data

    RA = 10:22:43.6, DE = +50:07:42
    Season = Feb 22
    
V = 9.732, J = 8.293 (23), K = 7.837 (21) -> B = 10.46(16), V = 9.70(10), Rc=9.28(8), Ic=8.88(6), B-V=0.76(19)
    HJDo = 4930.22001 (25) and P = 3.212220 (9) days (as listed in Schneider's Extrasolar Planets Encyclopaedia, HJDo corrected from earlier value)
    Depth =  14.0 ± 1.0 mmag
    Length = 2.87
± 0.03 hr

Finder image based on Palomar Observatory Sky Survey (POSS) B & R photographic plate images (converted to RGB color by SkyMap (http://sky-map.org/). Notice the fainter companion to upper-left. Bakos et al 2010 state that it's 2.58 mag's fainter (i'-band) and 9.1"arc away.
