SN 2010da
On May 23, 2010, Monard discovered another transient object of 16th magnitude, denoted as SN 2010da. The optical transient was detected 15".9 west and 16".8 north the center of the galaxy at coordinates 00 55 04.86 -37 41 43.7.
Two sets of independent follow-up spectroscopy data suggested that this was again another optical transient rather than a supernova, possibly an outbursting Luminous Blue Variable star according to one spectrum, as earlier predicted from the nature of the candidate mid-infrared progenitor. The transient faded by 0.5-0.7 mag in 9 days, much faster than the 2008 transient in NGC 300.
