Bulletin

NOAA AR 2736 has decreased in size and complexity (it has now beta magnetic field configuration) and did not produce anymore C-class flares in the past 24 h. It did produce many B-class flares, including a B9.9 peaking at 23:59 UT on March 23. The region is now rotating over the west limb, C-class flares remain possible but less likely.

No Earth directed CMEs in past 24 h. Solar protons have remained at background levels over the past 24 hours.

The solar wind speed is 265 km/s with interplanetary magnetic fields of 3 nT. The CME from March 20, expected to arrive yesterday (with 50% probability) has not done so yet. It may have been slowed down by the very slow solar wind that we are seeing now (in that case it could arrive today), or it may have missed the Earth. The fast solar wind emanating from a negative polarity equatorial coronal hole may affect the Earth in 48 h. Quiet conditions were observed in the past hours, the situation will change only if the CME arrives, in that case K up to 5 can be expected.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 017, gebaseerd op 24 stations.
