Päikese aktiivsed piirkonnad ja pursked

Solar flaring activity over the last 24h has been low, with five C-class flares. The strongest activity was a C2.6 flare associated with NOAA AR 3634 (alpha), peaking at 02:22 UTC. There are currently five active regions on the solar disk with NOAA AR 3633 (beta- gamma) being the most complex one. NOAA AR 3629 is currently rotating onto the west limb. A new currently unnumbered AR has rotated on disc from the north-east limb, but remains quiet. The solar flaring activity is expected to be at low levels over the next 24 hours, with C-class flares probable.

Krooniaine massiline väljavool

No Earth-directed coronal mass ejections (CMEs) were detected in the available coronagraph observations in the last 24 hours.

Krooniauk

A small, patchy, mid-latitude (south hemisphere), negative polarity coronal hole continues to reside on the central meridian. A related high-speed stream is expected to arrive on April 12th. A small, positive polarity, mid-latitude (northern hemisphere) coronal hole began to cross the central meridian around 07:00 UTC on April 10th. A related high- speed stream is expected to arrive on April 13th.

Päikesetuul

The Earth is inside the slow solar wind, with speed values ranging from 335 km/s to 480 km/s and an interplanetary magnetic field around 8 nT. The Bz component was fluctuating between -5 and 7 nT. The interplanetary magnetic field phi angle was predominantly in the positive sector. Mostly slow solar wind conditions are expected over the next 24 hours.

Geomagnetism

Geomagnetic conditions were globally at quiet to unsettled levels (NOAA Kp 0 to 3). Geomagnetic conditions were locally at quiet levels (K BEL 0 to 2). Similar conditions are expected in the next 24 hours.

Prootoni voo tasemed

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.

Elektronivoog geostatsionaarsel orbiidil

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.
