Solar activity has been dominated by the region on the east solar limb (NOAA AR 2268). It produced several C-class and one M1.4 flare at 04:52 UT. More M-class flares can be expected. Geomagnetic conditions were dominated by a fast speed stream that is now decaying. Planetary and local K indices reached 4. Quiet to unsettled conditions are expected.
