A X1.0 flare occurred on November 19, at 1026 UT (peak time), in NOAA AR 1893, close the west limb. The flare was associated with a metric type II burst, and an EUV coronal wave. There are preliminary observations of a CME linked to that event, as observed by the COR2 coronagraph on STEREO A, but only one frame shows the event and the speed is still unavailable. The position of the source region makes this event unlikely to be geoeffective, but more coronagraphic data are necessary to confirm this point.
