Aktywne obszary słoneczne i rozbłyski

The solar flaring activity remained at low levels. The strongest activity was marked by two C1.9 flares, produced by the newly numbered NOAA AR 3534 (beta), which contributed to most of the flaring activity over the past 24 hours, and by NOAA AR 3533 (beta). Isolated low levels of flaring was produced from over the west limb, possibly from NOAA AR 3526 and NOAA AR 3528. The largest active region on the visible disc, NOAA AR 3529 (beta), has shown some decay as it approaches the west limb. The remaining regions have shown no significant flaring activity nor signs of development. The solar flaring activity is expected to be at low levels over the coming days with probable C-class flares and minor chances for M-class flaring.

Koronalny wyrzut masy

No Earth-directed coronal mass ejections (CMEs) have been detected in the available coronagraph imagery over the past 24 hours.

Dziury koronalne

A large negative polarity equatorial coronal hole is expected to cross the central meridian later today. The high speed stream related to this coronal hole could arrive to Earth on Dec 31st.

Over the past 24 hours the solar wind parameters (ACE and DSCOVR) were indicative of slightly faster background slow solar wind conditions. The solar wind velocity weakly varied in the range of 417 km/s to 489 km/s. The interplanetary magnetic field had a maximum value of about 7 nT with a very weak minimum Bz of -2.8 nT. The B field was almost entirely in the positive sector (directed away from the Sun). The solar wind conditions in the next 24 hours are expected to be mostly at slow background solar wind conditions with remaining chances for slight disturbances due to any glancing blow arrival from the two CMEs from Dec 24th. Unperturbed solar wind conditions are expected thereafter until a possible high speed stream arrival on Dec 31st.

Geomagnetyzm

The geomagnetic conditions over the past 24 hours were quiet. Mostly quiet geomagnetic conditions are expected in the next 24 hours with possible isolated unsettled to active conditions in case of any delayed arrival of the CMEs from Dec 24th. Afterwards mostly quiet conditions are expected to prevail until an expected high speed stream arrival on Dec 31st.

Poziomy przepływu protonów

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

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV GOES 16 electron flux was below the 1000 pfu threshold and is expected to remain so in the upcoming days.The 24h electron fluence was at nominal level and is expected to remain so in the next days.
