Bülletään

Solar activity has been eruptive featuring several C-flares where two long duration flares where accompanied by CME's. Solar activity is expected to remain eruptive for the next 24 hours. The first CME was detected by SOHO on March 12th 11:00 UT and originated from AR NOAA 1690 with a long duration C2.0 flare at 10:17 UT. This halo CME with an angular width around 170 degrees might give Earth a glancing blow as seen in STEREO A & B. traveling at an estimated speed of 537 km/s it would reach Earth on Friday March 15th 21:00 UT. A second eruption took place after a long duration flare in AR NOAA 1692, but at the time of writing there is insufficient data available to provide more details. Solar wind speed is at a slow 315 km/s and the interplanetary magnetic field Bz component has near zero values. Geomagnetic activity was quiet to moderate and is expected to remain so for the next 48 hours after which it might reach storm conditions due to the CME of March 12th 11:00 UT.
