Extreme M-dwarf Flare Observed by ASAS-SN
The main scientific goal of ASAS-SN is to find bright nearby
supernovae in all kinds of galaxies, big and small. To achieve that,
we trigger on new objects (detected using image subtraction, see
APOW 2013/07/10), no matter if there is a known galaxy nearby or
not. This way, we also find many other interesting transients,
including this dramatic case of
ASASSN-13cb, an extreme delta V~9 mag (brightening in V-band by a
factor of 4,000) flare from an M-dwarf star. As can be seen from the
light curve of ASASSN-13cb, such flares last only few hours, but can
be very dramatic indeed.
