319 Leona and 341 California - Two Very Slowly Rotating Asteroids
Abstract
An observing strategy for asteroids suspected of being very slowly rotating is described and recommended to all observers. For 319 Leona the synodic rotation period is 430 ± 2 hours, amplitude 0.7 magnitudes, a second tumbling period is 1084 ± 10 hours, color index V-R = 0.43, H=10.46 ± 0.08 and G=0.11 ± 0.09 at mean light. For 341 California the synodic rotation period is 318 ± 2 hours, amplitude 0.9 magnitudes, a second tumbling period is 250 ± 2 hours, color index V-R = 0.53, H=11.53 ± 0.06 and G=0.18 ± 0.05 at mean light.
