CCD photometry of asteroids 651 Antikleia, 738 Alagasta, and 2151 Hadwiger using a remote commercial telescope

CCD photometry of asteroids 651 Antikleia, 738 Alagasta, and 2151 Hadwiger obtained remotely at Tenagra Observatories during March, April and May 2004 is reported. Our lightcurve period and amplitude results: 651 Antikleia, 20.287±0.004 hr, 0.40±0.05 mag; 738 Alagasta, 17.83±0.04 hr, 0.20±0.03 mag; 2151 Hadwiger, 5.872±0.002 hr, 0.35±0.02 mag. The three asteroids show nearly symmetrical lightcurves, although a complete lightcurve for Antikleia was not obtained. Three other asteroids (1926 Demiddelaer, 2375 Radek and 4293 Masumi) were also observed on seven nights, but no satisfactory lightcurves could be obtained.
