Photoelectric five-colour photometry of the asteroids 16 Psyche, 201 Penelope and 702 Alauda
Abstract
UBVRI photometry of 16 Psyche, 201 Penelope, and 702 Alauda have yielded light curves, colour indices, periods and phase effects. We find evidence for selective absorption on the planetoidal surfaces, and a rather uncertain indication of a large directively reflecting surface feature on Penelope.
