An exploding star in the spiral galaxy Messier 74 in Pisces, discovered last Thursday, had brightened to about magnitude 12.6 as of Tuesday morning. And it may not have reached its peak yet.

. Using a robotic telescope atop Mount Hamilton in California, the LOSS team announced that the system spotted a new 13.5-magnitude star about 2.7 arcminutes from the galaxy’s core on the morning of July 25th.
Supernova 2013ej is marked in this red-light image taken on July 28.7 using a robotic 20-inch telescope in Australia. It’s a stack of three 120-second-long exposures. The field is 12 arcminutes wide, with north up and east to the left.

Since its initial detection, the eruption (now designated Supernova 2013ej) has brightened to roughly magnitude 12.6 as of July 30th. Here’s an up-to-date light curve from the American Association of Variable Star Observers (AAVSO).
