ASASSN-13/SN 2013da: Our First Supernova Three Weeks Later

Our first supernova, ASASSN-13an/SN 2013da was discovered on June 5th 2013 using one of the 15-cm diameter "Brutus" telescopes. ASASSN-13an is a Type Ia supernova, the thermonuclear explosion of a white dwarf (or two), found by us in a galaxy about 330 million light years away. This picture, composed from VRI images, was taken by Jose Prieto three weeks later using IMACS camera mounted on the 6.5-m Baade Telescope in Las Campanas, Chile.
