Bulletin

Solar activity was very low with X-ray flux below B level throughout the period. The only region on disk (NOAA AR 2721) is in decay phase. A prominence erupted from the southwest limb of the Sun, yesterday morning, as observed by SDO/AIA 171 imagery. Event is not detected by LASCO/SOHO coronagraph imagery due to significant data gaps. The greater than 10MeV proton flux remained at background levels over the past 24 hours. Solar activity is expected to remain at very low levels. Solar wind speed varied from 450 and 370 km/s (DSCOVR). Bz varied between -5 and +5 nT. Solar wind parameters are expected to become enhanced later today due to the influence of a co-rotating intercation region followed by the influence of a positive polarity coronal hole high speed stream. Solar wind data from previous rotations and STEREO-A suggest maxium level of solar wind speed around 600 km/s. The geomagnetic field was mostly quiet. The geomagnetic field is expected to reach active levels later today. Minor (Kp = 5) and even moderate geomagnetic storm (Kp = 6) can be also expected tomorrow.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 011, gebaseerd op 16 stations.
