An active region behind the east limb produced an X1.7 flare with peak at 02:17 UT and several M class flares. There were Type II and III radio bursts and a CME associated with this flare. The CME is not expected to arrive to the Earth. Active conditions are expected with more M and X class flares possible, in particular when this AR rotates over the visible disk in a few days. C and M class flares can be expected mostly from NOAA AR 1744, 1745 and 1746. Geomagnetic conditions are quiet, unsettled conditions may occur with the expected arrival of a mildly fast speed stream from a coronal hole today and tomorrow.
