Magnitudes of selected stellar occultation candidates for Pluto and other planets, with new predictions for Mars and Jupiter
Occultation predictions for the planets Mars and Jupiter are presentedalong with BVRI magnitudes of 45 occultation candidates for Mars,Jupiter, Saturn, Uranus, and Pluto. Observers can use these magnitudesto plan observations of occultation events. The optical depth of theJovian ring can be probed by a nearly central occultation on 1992 July8. Mars occults an unusually red star in early 1993, and theoccultations for Pluto involving the brightest candidates would possiblyoccur in the spring of 1992 and the fall of 1993.

Interstellar reddening in the Southern Hemisphere. I - The UVBY beta observations
The uvby-beta photometric data obtained from a Southern Hemisphereobservational project is presented. A uvby-beta photometric network ofnearly 3900 A and early F stars has been established with the intentthat the stars serve as 'space probes' for measurements of interstellarreddening.
