A three-color composite EUV image covering both active regions, just at the time (10:50:08) of the hard X-ray spike seen by GBM. A huge jet development can be seen pushing almost directly S; the darkness around the region is the result of [coronal dimming] that has already begun. The movies do not show any obvious evidence of a disturbance propagating between the two regions, but this jet is a powerful injection into the corona above them. ]]
