(471155) 2010 GF_65
     B. Proudfoot, Florida Space Institute; and W. Grundy, Northern Arizona 
University, report that the transneptunian object (471155) is a tight,
approximately equal-sized binary, where the secondary is 0.02 +/- 0.01 mag 
fainter than the primary.  The binary was discovered in two 300-s Hubble Space 
Telescope exposures taken with the WFC3/UVIS camera (+ F350LP filter) on 2019 
July 2 (HST Program 15344, P.I. D. Jewitt).  At the time of the HST imaging, 
the resolved components were separated by 0".090 +/- 0".001 in p.a. 242.4 +/- 
0.4 deg.  At the time of the first image (2019 July 2.78961 UT), the primary
was located at R.A. = 16h14m41.35s, Decl. = -33d27'39".8 (equinox J2000.0).
