Asteroid 785 (Zwetana) Light Curve, May 2005

combination of 6 nights of data
Y scale in millimag (1 tick = 5 millimag)
X scale in millidays

Asteroid 2002 QF15 - Collaboration with Wise Observatory.  Observed a slowly rotating asteroid first in Israel and then in New Mexico to get the light curve (7/23/06):
