[Maxim Usatov]

Was able to do photometry today in Astrometrica. Have it at V = 15.77 ± 0.05, although correct PSF fit is a little difficult.

Observatory:  New Mexico Skies at Mayhill, New Mexico - MPC H06
Telescope:  0.50-m f/6.8 reflector + CCD + f/4.5 focal reducer
CCD:  FLI ProLine PL11002M CCD camera

Filter is Astrodon V.

Still at about the same magnitude tonight, V = 15.778.
