Aktywne obszary słoneczne i rozbłyski

The solar flaring activity was at low level during the last 24 hours, with few C-class flares. The strongest flare was GOES C3.1 flare from NOAA AR 3530 which peaked at 09:14 UTC on Dec 23. During the flare, the source region (AR 3530) of the flare had beta configuration of its photospheric magnetic field. The solar flaring activity is expected to be at low to moderate levels over the next 24 hours with few C-class flares and possibly M-class flares.

Koronalny wyrzut masy

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

Dziury koronalne

A negative polarity coronal hole (CH), possibly connected to the southern polar CH spanning from 30 - 55 S, crossed the central meridian on Dec 20 and a high speed stream from this CH may arrive to Earth from Dec 23.

Wiatr słoneczny

Earth is presently within the slow solar wind regime, velocity ranging from 300 km/s to 360 km/s. The North-South component (Bz) ranged between -6 and 7 nT. The interplanetary magnetic field ranging from 4 nT to 8 nT. The fast solar wind originating from the negative polarity coronal hole (CH), possibly connected to the southern polar CH spanning from 30 - 55 S, which reached the central meridian in the morning of Dec 18 is expected to impact the Earth in the coming hours.

Geomagnetyzm

Geomagnetic conditions were globally at quiet to unsettled conditions (NOAA Kp 1 to 3). It was locally at quiet conditions (K BEL 1 to 2). We expect to see unsettled to active conditions if the fast solar wind originating from the negative polarity coronal hole (CH), possibly connected to the southern polar CH spanning from 30 - 55 S, which reached the central meridian in the morning of Dec 18 impacts the Earth in the coming hours.

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, as measured by the GOES-16 satellite, reached above the threshold level at 09:40 UTC and dropped below at 21:00 UTC on Dec 22. It is expected that this parameter to remain below the threshold level in the coming 24 hours. The 24h electron fluence is presently at normal to moderate levels and is expected to decrease to normal level in the coming 24 hours.
