Päikese aktiivsed piirkonnad ja pursked

Solar flaring activity was at low levels in the past 24 hours. The largest flare was a C1.5 flare, peaking at 19:58 on Oct 23, associated with NOAA AR 3468 (alpha class). NOAA ARs 3469 and 3471 decayed into a plage regions. NOAA AR 3470 (beta class) did not show any significant flaring activity. The solar flaring activity is expected to be at very low to low levels over the next 24 hours with a chance for C-class flares.

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

Päikesetuul

Over the past 24 hours the solar wind parameters were reflecting near slow solar wind conditions. The solar wind speed ranged between 360 - 380 km/s. The interplanetary magnetic field magnitude was below 7 nT. The southward component of the interplanetary magnetic field fluctuated between -3 nT and 6 nT. Similar conditions are expected in the next 24 hours, with a small chance of a week enhancement on Oct 24 due to high-speed stream influence from the small negative polarity coronal hole, which crossed the central meridian on Oct 19. On Oct 26 solar wind parameters might be slightly elevated due to the arrival of a high-speed stream from a positive polarity equatorial coronal hole, that transited the central meridian on Oct 23.

Geomagnetism

Geomagnetic conditions were quiet (NOAA Kp: 0 to 1 and K-BEL: 0 to 2). Geomagnetic conditions are expected to be at quiet to unsettled levels with a small chance for isolated active periods on Oct 26 in response to the high-speed stream arrival associated with the small equatorial coronal hole (positive polarity) that transited the central meridian on Oct 23.

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.
