(31345) 1998 PG: A BINARY NEAR-EARTH ASTEROID?

Photometric observations of the near-Earth asteroid (31345) 1998 PG by Pravec et al. (2000) found a rotation period of 2.51620 h.

1943 ANTEROS: A POSSIBLE NEAR-EARTH BINARY ASTEROID.

A collaboration of two observers at widely-separated longitudes made CCD photometric observations of the near-Earth asteroid (NEA) 1943 Anteros from 2016 August to October. Analysis of the data led to the possibility that the asteroid is a binary with = 2.86923 ± 0.

PRELIMINARY POLE AND SHAPE MODELS FOR THREE NEAR-EARTH ASTEROIDS.

Observations of three near-Earth asteroids (NEAs) were made between 1993 and 2016. The resulting data were used to find preliminary pole and shape models for 1863 Antinous, (5836) 1993 MF, and (154244) 2002 KL6.

LIGHTCURVE ANALYSIS OF NEA (331471) 1984 QY1: A TUMBLING ASTEROID.

Analysis of CCD photometric observations of the near-Earth asteroid (331471) 1984 QY1 show that it is likely in non-principal axis rotation (NPAR), or tumbling. A single period analysis found a dominant period of 45.5 ± 0.

LIGHTCURVE ANALYSIS OF NEA (154244) 2002 KL6: A POTENTIAL NEW BINARY ASTEROID.

Analysis of CCD photometric observations of near-Earth asteroid (154244) 2002 KL6 indicate that it may be a binary system. The presumed primary has a synodic rotation period of 4.60869 ± 0.

5426 SHARP: A PROBABLE HUNGARIA BINARY.

Initial CCD photometry observations of the Hungaria asteroid 5426 Sharp in 2014 December and 2015 January at the Center of Solar System Studies-Palmer Divide Station in Landers, CA, showed attenuations from the general lightcurve, indicating the possibility of the asteroid being a binary system. The secondary period was almost exactly an Earth day, prompting a collaboration to be formed with observers in Europe, which eventually allowed establishing two periods: = 4.5609 ± 0.

LIGHTCURVE ANALYSIS OF THE NEAR-EARTH ASTEROID (162566) 2000 RJ34.

Analysis of CCD photometry observations of the near-Earth asteroid (162566) 2000 RJ34 indicates a period of 50.5 ± 0.1 h.

LIGHTCURVE ANALYSIS OF NEAR-EARTH ASTEROID 2010 TN54.

CCD photometry observations of the near-Earth asteroid (NEA) 2010 TN 54 indicates a period of either 6.14 h or 12.12 h, depending on whether a monomodal or bimodal lightcurve is adopted.
