Period Change and Surface Activity of the Eclipsing Binary UV Leonis
From Johnson B and V photometric measurements of V=8.98 mag eclipsingbinary UV Leonis we calculated the epochs of primary and secondaryminima, which we used to complement the published O-C catalog by Kreineret al. (2000). From this we give a brief analysis of the observed periodchange and give qualitative presumptions about the physics that mighthave caused such a change. Further on, we use the observed systematicvertical shift in light curves as an indication of the surface activityof UV Leonis.

ICCD Speckle Observations of Binary Stars.XV.An Investigation of Lunar Occultation Systems
Abstract image available at:http://adsabs.harvard.edu/cgi-bin/nph-bib_query?1996AJ....112.2260M&db_key=AST

Photoelectric observations of lunar occultations. XV
The last (or possibly penultimate) paper in a series on lunaroccultations presents observations of 404 phenomena, preceded by somegeneral remarks of a retrospective nature. The series of observationsbegan in 1968. Data for 20 doubles or suspected doubles are presented,ranked in order of certainty, with designation 3 representing thesurest. Thirteen of the cases refer to stars not previously noted asdoubles. Seven determinations of angular diameters are presented, ofwhich three have been previously observed.
