公告

GOES reported a long duration C flare early this morning, March 23. An EUV wave was seen in SDO/AIA 193 images originating from the location of NOAA AR 2014. A CME is visible in LASCO/C2 from 5:12UT (data gap from 0:48UT until 5:12UT). A first estimate of the speed based on STEREO B/COR2 images gives a value around 800 km/s. A glancing blow is not excluded on March 26-27. We expect more C-flaring activity. The probability for M-flares is around 40%. ACE parameters show an increase in the solar wind magnetic field strength from March 21 followed by a decrease from late March 22. The solar wind speed picked up gradually from March 22. The solar wind blows today, March 23 at a speed of around 450 km/s with a lower density compared with the previous days. This behaviour of the solar wind parameters is typically associated with the interaction of a slow and fast solar wind. The fast solar wind can be probably linked with the equatorial coronal hole that was at the central meridian on March 20.The geomagnetic impact is negligible. We expect quiet geomagnetic conditions.
