Aktywne obszary słoneczne i rozbłyski

The solar flaring activity was at moderate level during the last 24 hours, with few C-class flares and a M-class flare. These flares were mostly produced by the NOAA Active Region (AR) 3599. The strongest reported flare was GOES M1.3 flare which peaked at 21:26 UTC on Mar 08. During the flare, the source region (AR 3599) of the flare had beta-gamma-delta 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 several C-class flares, and a chance for M-class flares.

Koronalny wyrzut masy

A narrow coronal mass ejection (CME) was observed in SOHO/LASCO-C2 images at 12:12 UTC on Mar 08. It was associated with a filament eruption on the NE quadrant, and this CME is not expected to impact the Earth. Another partial CME was first observed in LASCO-C2 images at 05:12 UTC on Mar 09. It is associated with a prominence eruption (about 03:24 UTC) on the SE limb. It has a projected speed of 1562 km/s and a projected width of 130 degree (as measured by Cactus tool). Due to the main propagation direction of the CME being strongly south east from the Sun- Earth line, the CME-flank encounter is not possible at Earth but glancing blow cannot be excluded. Further analysis is going-on to investigate if this CME has Earth directed components. No other Earth directed component of CME has been identified in the available coronograph imagery.

Dziury koronalne

A narrow (positive polarity) coronal hole, spanning 15 - 30 N, is approaching the central meridian on Mar 09. The solar wind from this coronal hole may enhance the solar wind environment near Earth on Mar 12.

Wiatr słoneczny

Over the past 24 hours, the solar wind parameters were still under the influence of high speed streams (HSSs) from the equatorial (negative polarity) coronal hole which crossed the central meridian on Mar 06. The solar wind speed ranged between 430 km/s to 540 km/s. The North- South component (Bz) ranged between -6 and 5 nT. The interplanetary magnetic field ranged between 2 nT and 7 nT. In the next 24 hours, we expect a gradual transition from fast to slow solar wind unless the shock driven by coronal mass ejection (CME), which was observed at 21:24 UTC on Mar 05, arrives later than expected at Earth.

Geomagnetyzm

Geomagnetic conditions were globally and locally at quiet to active conditions (NOAA Kp and K BEL 1 to 4) due to the continuous impact of high speed streams from the equatorial (negative polarity) coronal hole, which crossed the central meridian on Mar 06. In the next 24 hours, active to minor storm conditions may be expected if the shock driven by coronal mass ejection (CME), which was observed at 21:24 UTC on Mar 5, arrives later than expected at 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.
