Bulletin

Solar activity was at very low levels in the past 24 hours. NOAA AR 2811 and 2812 produced only B-class flares. Solar activity is expected to remain at low levels.

No Earth directed CMEs were observed in the past 24 hours.

The equatorial negative polarity coronal hole that started crossing the solar central meridian on 24 March continued the crossing today. Its associated high speed stream will arrive at the Earth in about 24 hours.

The greater than 10 MeV proton flux was below nominal levels over the past 24 hours and is expected to remain so for the next 24 hours. The greater than 2 MeV electron flux was below the 1000 pfu threshold in the past 24 hours and is expected to remain so during the next 24 hours. The 24h electron fluence dropped from moderate to normal levels in the last 24 hours and is expected to stay at normal levels for the next 24 hours.

The solar wind speed varied between 400 km/s and 500 km/s in the last 24 hours. The interplanetary magnetic field magnitude varied between 1.3 nT and 7.5 nT, while Bz varied between -5 nT and 5 nT in the last 24 hours. The magnetic field phi angle varied a lot and had positive and negative polarities for approximately the same length of time. Slow solar wind conditions are expected in the next 24 hours. A transition to fast solar wind is expected after the next 24 hours.

Geomagnetic conditions varied from quiet to minor storm levels globally (Kp: 1-4), and from quite to unsettled locally (K Doubres: 1-3). The ICME corresponding to the CME of 22 March is expected to arrive within the next 24 hours, and increase the geomagnetic conditions to active or minor storm levels.
