Päikese aktiivsed piirkonnad ja pursked

The solar flaring activity was at low levels, with several C-class flares recorded in the past 24 hours. There are currently only two numbered active regions on the solar disk with sunspots remaining. The largest flare was an C3.0 flare, peaking at 22:44 on Oct 25, associated with NOAA AR 3471 (beta class). NOAA AR 3468 (alpha class) did not show any significant flaring activity. The solar flaring activity is expected to be at low levels over the next 24 hours with a C-class flares possible.

Krooniaine massiline väljavool

No Earth directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph imagery.

Päikesetuul

Over the past 24 hours, the solar wind conditions became slightly disturbed with the total interplanetary magnetic field rose to 13 nT at around 08:30 UTC on 26 Oct. The southward component of the interplanetary magnetic field ranged between -12 nT and 8 nT. The solar wind speed followed an increasing trend, rising from 310 km/s to 380 km/s. The magnetic field orientation was variable at the start of the period before switching to the predominantly positive sector (field directed away from the Sun) from 19:30 UTC on Oct 25. This might be associated with arrival of the compression region in front of the expected HSS from a positive polarity coronal hole. Solar wind parameters are expected to remain slightly elevated in the next days due to HSS arrival associated with the positive polarity coronal hole, that transited the central meridian on Oct 23.

Geomagnetism

Geomagnetic conditions over the past 24 hours were quiet to unsettled (NOAA Kp: 1 to 3 and K-BEL: 1 to 3). Geomagnetic conditions are expected to be at quiet to unsettled levels with a chance for isolated active and minor storm periods in response to the high-speed stream arrival from a positive polarity coronal hole.

Prootoni voo tasemed

Over the past 24 hours the greater than 10 MeV GOES proton flux was at nominal levels and is expected to remain so over the next days.

Elektronivoog geostatsionaarsel orbiidil

The greater than 2 MeV electron flux remained below the 1000 pfu threshold as measured by GOES 16. It is expected to remain below this threshold over the next days. The 24 hour electron fluence was at normal levels and is expected to remain so.
