According to AAVSO Special Notice #250 Matthew Templeton reports that
there is a possible Type-Ia Supernova in M101.
P. Nugent et al. report in ATel #3581 that a possible Type-Ia
supernova has been discovered by the Palomar Transient Factory shortly
after eruption in the galaxy M101 and has been designated "PTF11kly".
The object, when discovered on August 23/24, was at a magnitude of
g=17.2, but already by late August 24 was at 14.5V/v and it may reach
mag 10 or 11. The object is well placed within M101 for good
photometry, and observations of this potential bright SNIa are
strongly encouraged.
The (J2000) coordinates reported for the object are
RA: 14:03:05.81 , Dec: +54:16:25.4
Charts using the name PTF11kly may be plotted with the AAVSO VSP at
http://www.aavso.org/vsp
You should select the DSS option when plotting, as the galaxy will not
appear on standard charts.
