BINARY ASTEROID LIGHTCURVE ANALYSIS AT THE CS3-PALMER DIVIDE STATION: 2013 JUNE-SEPTEMBER.

Lightcurves from CCD photometry observations for four suspected or confirmed binary asteroids were obtained at the Center for Solar System Studies-Palmer Divide Station (CS3-PDS) from 2013 June through September. All four objects are members of the Hungaria family/group. 5968 Trauger showed signs of a satellite based on a single possible event. (11217) 1999 JC4 is a more likely candidate based on a strong secondary period; no mutual events were observed, however. (15822) 1999 TV15 is the most likely new binary discovery by the author, showing mutual events in its lightcurve, albeit they were close to the limit of detection. (76818) 2000 RG79 was a known binary asteroid (Warner et al., 2005). The 2013 observations provided additional data for modeling the system.
