Aktywne obszary słoneczne i rozbłyski

The solar flaring activity was at very low levels. No significant flaring activity has been recorded. NOAA AR 3467 and 3465 decayed into plage regions. The three remaining regions on disk, NOAA ARs 3469, 3468 and 3470 were stable and quiet. The solar flaring activity is expected to be at very low levels over the next 24 hours with a low probability of C-class flares.

Koronalny wyrzut masy

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

Dziury koronalne

A small equatorial positive polarity coronal hole began to transit the central meridian on October 22.

The solar wind parameters were indicative of ongoing weak transient magnetic structures, possibly associated to one of the predicted glancing blow CME arrivals. The interplanetary magnetic field ranged between 2 and 9nT. Bz was predominantly negative with a minimum Bz of -7nT. The solar wind speed was at background levels between 270 and 320 km/s. The interplanetary magnetic field orientation continually switched between the positive sector (field directed away from Sun) and the negative sector (field directed towards the Sun). The interplanetary magnetic field is expected to remain slightly enhanced on 22, due to ongoing possible CME influences. The expected interaction region and weak high-speed stream from the small negative polarity coronal hole, which crossed the central meridian on 19, could increase the solar wind speed slightly over the next days.

Geomagnetyzm

During last 24 hours the geomagnetic conditions were at unsettled levels at the start of the period and then decreased to quiet levels from 21:00 UTC October 22 (NOAA KP 1-3+ and K Bel 1-3). Geomagnetic conditions are expected to be at quiet to unsettled on October 22, with active intervals possible from October 23, due the influence of the high speed stream.

Poziomy przepływu protonów

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.

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 nominal levels. The electron fluence is expected to be at nominal levels for the next days.
