T Andromedae (also known as T And, BD +26° 43, SAO 73930 and HD 1795) is a type M3e Mira variable star located in the constellation Andromeda. It shines at an apparent visual magnitude of between +7.70 to +14.30, with a variability period of 280.1 days. T Andromedae was discovered (by its absence) by Scottish clergyman and amateur astronomer Dr. Thomas David Anderson using a 2¼ inch refractor at 21 East Claremont Street in Edinburgh, in November 1893. Dr. Thomas David Anderson corresponded with Sir Robert Ball and Karl Friedrich Küstner who did further follow-up observations of the star, and showed it to be variable.
