2011.8.23，发现M101爆发超新星 Ia 型，临时编号：PTF11kly，正式SN 2011fe
8.22没有观测到，8.24变得更亮.
这次爆发的 Ia 型，若要找到相近规模的，得追溯1972，1937, 1898, 和1572
这次发现的超新星爆发，离我们2100万光年之遥
乐观猜测，接下来10天左右，用质量好的双筒可能可以观测到
Scientists from the University of Oxford made the discovery with their colleagues from the Palomar(48-inch Samuel Oschin Telescope ) Transient Factory (PTF) collaboration, using a robotic telescope in California in the United States.

Supernova in M101, Aug 25th, full processingIt’s about a total 3 hr exposure with a 11in CPC1100, using a canon 60d (iso 2500). 30s exposures, throwing away bad exposures (about 60 %) to yield this using deepskystacker (using about 50 dark frames). The arrow indicates the supernova.Thunderf00t
