Assassin Picture of the Week

2013 December 21

Back in Real-Time Discovery Business!

As you know, back in late October Brutus has expanded from two to four telescopes. We returned to regular data-taking operations almost immediately, but, as expected, it took us several weeks to be able to again process the data in real-time.

ASASSN-13dm is our first supernova discovered using four-telescope configuration. ASASSN-13dm was discovered in images obtained 2013 UT Dec. 4.86 at V 15.9, but was undetected (V > 17) in images obtained on 2013 UT Nov. 19.96. ASASSN-13dm was also detected in images taken on 2013 UT Dec. 5.85, 6.83, 7.84, and 9.83. The transient is located near PGC 2816341 (z=0.017, d=70 Mpc), which would give it an absolute V mag of approx. -18.7. One thing to notice is that the supernova was there, quite bright, for more than a week before we discovered it. This, along with other ASAS-SN discoveries, demonstrates the need for an all-sky discovery machine like ASAS-SN.
