Bulletin

The solar activity has been quiet over the past 24 hours. The active region (NOAA 2704, Mcintosh class: Bxo, Mag. type: Beta) has produced few small flares. The flaring conditions are expected to remain mostly quiet for the next 24-hour period with a small chance of C-class flare.

No Earth directed Coronal Mass Ejection has been observed. The greater than 10 MeV solar protons flux remained at nominal levels over the past 24 hours and is expected to remain so.

The solar wind parameters have shown a return towards the ambient- background and slow solar wind speed regime. The solar wind speed has continuously decreased from around 450 to 390 km/s over the past 24 hours. The total magnetic field strength remained below 6 nT, and the Bz component was fluctuating between -4.5 and +5.7 nT. Solar wind conditions are expected to return to the slow regime by the end of this 24-hour period.

Geomagnetic conditions have been mostly quiet over the past 24 hours. A slightly more active period was observed: local K (Dourbs) was 3 between 22:00 UT on April 13 and 02:00 UT on April 14, and Kp index (NOAA) has reached 4 on April 14 at 01:00 UT. With the decay of the solar wind speed, the geomagnetic conditions are expected to remained mostly quiet for the next period.
