  • We report the discovery of a microlensing candidate projected 2'54'' from the center of M32, on the side closest to M31. The blue color (R-I = 0.00 ? 0.14) of the source argues strongly that it lies in the disk of M31, while the proximity of the line of sight to M32 implies that this galaxy is the most likely host of the lens. If this interpretation is correct, it would confirm previous arguments that M32 lies in front of M31. If more events are discovered in this direction in a dedicated… CONTINUE READING
