Aktywne obszary słoneczne i rozbłyski

Solar flaring activity over the last 24 hours has been low, with multiple C-class flares. The strongest activity was a C3.5 flare associated with NOAA AR 3635 (beta), peaking at 11:10 UTC. There are currently four active regions on the solar disk with NOAA AR 3633 (beta-gamma) being the most complex one. NOAA AR 3632 has decayed into plage. The solar flaring activity is expected to be at low levels over the next 24 hours, with C-class flares probable.

Koronalny wyrzut masy

No Earth-directed coronal mass ejections (CMEs) were detected in the available coronagraph observations in the last 24 hours. A filament eruption was observed on SDO/AIA 304 data at 06:30 UTC near the central meridian. It will be analysed when coronograph observations become available.

Dziury koronalne

The small, patchy, mid-latitude (south hemisphere), negative polarity coronal hole that was reported on April 9th and 10th has crossed the central meridian. A related high-speed stream is expected to arrive on April 12th. The small, positive polarity, mid-latitude (northern hemisphere) coronal hole that was reported on April 10th continues to reside on the central meridian. A related high-speed stream is expected to arrive on April 13th.

Wiatr słoneczny

The Earth is inside the slow solar wind, with speed values ranging from 406 km/s to 492 km/s and an interplanetary magnetic field around 7nT. The Bz component varied between -6 nT and 7 nT. The interplanetary magnetic field phi angle was predominantly in the positive sector. Possible enhancements in the solar wind speed, due to a high-speed stream associated with the negative polarity coronal hole, may be expected over the next 24 hours.

Geomagnetyzm

Geomagnetic conditions were globally and locally at quiet or unsettled levels (NOAA Kp and K BEL 0 to 3). Active conditions are expected over the next 24 hours due to the influence from the negative polarity coronal hole.

Poziomy przepływu protonów

The greater than 10 MeV proton flux was below the threshold level over the past 24 hours and is expected to remain so for the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux was below the threshold level in the last 24 hours and is expected to remain so in the coming 24 hours. The 24h electron fluence is presently at normal levels and is expected to remain so in the coming 24 hours.
