Bulletin

Solar activity has been quiet with only two small C flares with the largest one a C2.5 flare originating from NOAA 1652. Solar activity is expected to remain quiet with possibly an isolated C flare. Geomagnetic activity reached storm level on January 17th between 15:00 UT and 18:00 UT. Ace IMF data of this period shows a jump of the magnetic field strength from 5 nT to 15 nT with a negative Bz component. There was no shock detected in the ACE solar wind data. This geomagnetic activity is likely related to the slow CME of Sunday January 13th 13:00 UT (as seen in LASCO C2). Geomagnetic activity is possible to rise in the night of January 19th- 20th due to the CME of January 16th 19:12 UT (as seen in LASCO C2).

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 028, gebaseerd op 03 stations.
