The supernova in the Pinwheel Galaxy (M101) has now been designated “SN2011FE” (formerly “PTF11kly” which was even more difficult to remember). It continues to brighten. Comparing my measurements over the past two nights, it has brightened half a magnitude, from 12.9 to 12.4 in the past 24 hours. This is consistent with observations submitted by others to the AAVSO:
