Skrót wiadomości

Over the past 24 hours solar activity has been low. The largest flare was a B8.6 class flare, produced by Active Region (AR) 2529 (Eho;Beta), which peaked at 07:57 UT this morning. Another region AR 2530(Bxo,Beta) is currently present on disk. Solar activity is expected to remain low over the next 24 hours. A slow partial halo Coronal Mass Ejection (CME) with the initial speed around 200 km/sec has been detected yesterday at 02:36 UT, which evolved from a slow filament eruption (first detected at 00:50 UT 12-Apr-2016) at the backside of the Sun as seen from the STEREO-Ahead imagery. Solar protons have remained at background levels over the past 24 hours. The solar wind parameters showed the arrival of the expected coronal hole high speed stream. The speed increased from around 18:00 UT 12-Apr-2016 reaching a peak of around 700 km/s at around 06:00 UT today. Simultaneously, the total magnetic field strength in solar wind has increased till around 17 nT, while Bz component of the magnetic field decreased till -14 nT and remained negative during the rest of the afternoon. In response minor geomagnetic storm conditions have been recorded around midnight (NOAA Kp ranged between 3 to 5, local K index Dourbes ranged between 2 to 5). Conditions have meanwhile slightly decayed, but active geomagnetic conditions are still recorded at the planetary level. Over the next 24 hrs solar wind conditions may remain elevated and associated active geomagnetic conditions can be expected. Afterwards conditions are expected to recover to the nominal level.
