Comet outburst

Rosetta’s OSIRIS wide-angle camera captured an outburst from the Atum region on Comet 67P/Churyumov–Gerasimenko’s large lobe on 19 February 2016. The images are separated by half an hour each, covering the period 08:40–12:10 GMT, and as such show the comet rotating. Brightening in an initially shadowed region is first seen in the 09:40 image, with significant increase in brightness in subsequent images before subsiding again. The structure of more defined streams of dust and gas is also visible in later images.
