- The MACHO Project database was searched for aperiodic blue variables in the LMC. Of approximately 250,000 bright blue stars in the region of observation, around 3500 had been flagged as variables or as rejected gravitational microlensing candidates. From a visual inspection of this set, about 400 stars were selected for the catalog. These stars have been categorized by their light curve morphology. Their spatial distribution is presented and correlated with known phenomena. Analysis of the catalog stars has produced some interesting discoveries. Among some of these variables, unusual color changes were found. Some stars become redder or do not change color when their brightness increases, whereas most stars become bluer if they brighten rapidly. For some stars with relatively long quiescent stages, the light curves were searched for low-level, periodic variability, but no conclusive evidence for such behavior was found.
