Bulletin

Solar activity remained low. NOAA active region 2732 produced one B1.9 flare peaking at 17:14 UT yesterday (January 3). No geoeffective coronal mass ejections (CMEs) were observed over the last 24 hours. The greater than 10 MeV proton flux was at nominal values. Solar activity is expected to remain at low levels with some probabailty for C-class flares. Solar wind speed abruptly increased from about 300 till 350 km/s this morning, January 4 (DSCOVR). Simultanioulsy interplanetary magnetic field amplitute increased till 9 nT, while Bz started to vary between -7 nT and +7 nT. The geomagnetic conditions were quiet. However, unsettled to active geomagnetic conditions can be expected later today (4 January) due to the increasing influence of the wind stream associated with the negative polarity equatorial coronal hole. An isolated minor storm can be expected tomorrow (Januray 5).

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 014, gebaseerd op 13 stations.
