Abstract

Nova LMC 2005 was discovered on November 26, 2005, at approximate magnitude 11.5. Fainter photographic images were detected four nights earlier, and the ASAS-3 sky survey recorded it at V = 11.695 one night before discovery. Its evolution thereafter was closely followed in V, B, and R by the four of us, and the decline found to be slow with sizeable fluctuations. We present herewith the observational data and comment on their significance.
