Abstract

Asteroids (6), (14), (39), and (51) were observed at the Leiden Southern Station. Only (39) Laetitia seems to show some variation in color (3% in visual-ultraviolet) correlated to the light curve. If a similar effect is present for (6) Hebe, it should only be present at small phase angles. The light curves of (14) Irene and (39) Laetitia show light variations of a few percent of the rotational period indicating probable surface macrostructure.
