Aktywne obszary słoneczne i rozbłyski

The solar flaring activity was low during the last 24 hours with few C-class flares, all produced by NOAA Active Region (AR) 3599. The strongest reported flare was GOES C8.3 flare which peaked at 06:18 UTC on Mar 07. During the flare, the source region (AR 3599) of the flare had beta-gamma 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 a chance for M-class flares.

Koronalny wyrzut masy

A coronal mass ejection (CME) was first observed in SOHO/LASCO-C2 images on 11:37 UTC on Mar 06. It is associated with a C1.0 flare from the NOAA AR 3592 and a nearby filament eruption. It has a projected speed of 260 km/s and a projected width of about 90 degrees. This eruption was followed by a subsequent small filament eruption on the east of central meridian (possibly triggered by the wave associated with the first filament eruption), an associated narrow CME was observed in LASCO-C2 images at 13:09. These CMEs are not expected to arrive at the Earth. There were no other Earth-directed CMEs detected in the available coronagraph observations during last 24 hour. A large filament eruption was observed on SE quadrant around 06:39 UTC today and a possibly associated CME could have Earth-directed components. We are awaiting for the corresponding coronagraph data for further analysis.

Dziury koronalne

A small equatorial (negative polarity) coronal hole crossed the central meridian on Mar 06. The solar wind from this coronal hole may enhance the solar wind environment near Earth on Mar 08.

Wiatr słoneczny

Earth is presently within the slow solar wind regime. The solar wind speed ranged between 350 km/s and 430 km/s. The North-South component (Bz) ranged between -4 and 6 nT. The interplanetary magnetic field ranged between 0 nT and 7 nT. Slow solar wind conditions are expected to continue over the next 24 hours unless the high speed streams originating from the small equatorial (negative polarity) coronal hole, which started to cross the central meridian on Mar 05, impacts the Earth.

Geomagnetyzm

Geomagnetic conditions were globally and locally at quiet to unsettled conditions (NOAA Kp and K BEL 1 to 3). In the next 24 hours, it is expected to remain so unless the high speed streams originating from the small equatorial (negative polarity) coronal hole, which started to cross the central meridian on Mar 05, impacts the Earth.

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, was below the threshold level in the last 24 hours. It is expected that this parameter to remain below the threshold level in the next 24 hours. The 24h electron fluence is presently at normal level and is expected to remain so in the coming 24 hours.
