ASTEROID LIGHTCURVE ANALYSIS AT CS3-PALMER DIVIDE STATION: 2013 MAY-JUNE.

Lightcurves for eleven asteroids were obtained at the Center for Solar System Studies-Palmer Divide Station (CS3-PDS) in 2013 May and June. The asteroids were a mostly a mix of Hungaria and Phocaea members along with some outer main-belt asteroids. New data failed to remove the existing rotation period ambiguity for the Hungaria asteroid 1355 Magoeba, although the number of possibilities may have been reduced. A new period is proposed for 4436 Ortizmoreno, 8.24 h (or 16.48 h), superseding the one reported by Birlan et al. (1996). The Hungaria member 26074 Carlwirtz may be a binary with a primary rotation period of P 1 = 2.5493 ± 0.0003 h and a satellite orbital period of P orb = 16.11 ± 0.02 h. The Phocaea member (125742) 2001 XT117 shows signs of a low amplitude precision period, i.e., it is possibly in non-principal axis rotation (NPAR).
