Aktywne obszary słoneczne i rozbłyski

Solar flaring activity during the last 24 hours has been low, with only C-class flares. The strongest flare was a C3.9 flare (SIDC Flare 7131), peaking at 03:09 UTC on March 04, associated with SIDC Sunspot Group 805 (NOAA Active Region 4384, magnetic type beta). There are currently six numbered active regions on the solar disk. The most complex ones have a beta magnetic type. SIDC Sunspot Groups 803, 807 and 808 have decayed into plage. SIDC Sunspot Group 810 (magnetic type beta) has emerged in the northwest quadrant. SIDC Sunspot Group 811 (magnetic type beta) has emerged in the southeast quadrant. The solar flaring activity is expected to be low over the next 24 hours, with C-class flares very likely and a chance for M-class flares.

Koronalny wyrzut masy

No Earth-directed Coronal Mass Ejections (CMEs) were observed in the available coronagraph imagery during the last 24 hours.

Dziury koronalne

An equatorial, negative polarity coronal hole (SIDC Coronal Hole 149) is crossing the central meridian. An associated high-speed stream may arrive at Earth starting from March 07.

Wiatr słoneczny

Over the last 24 hours, the solar wind parameters (ACE and DSCOVR) reflected a possible influence from a mild high-speed stream, likely from either SIDC Coronal Hole 152 (northern, positive polarity) or SIDC Coronal Hole 153 (southern, positive polarity). The solar wind speed increased from 400 km/s to 450 km/s. The interplanetary magnetic field decreased from 11 nT to 6 nT. The Bz component varied between -10 nT and 6 nT. The interplanetary magnetic field angle phi was predominantly in the positive sector. Mostly slow solar wind conditions are expected over the next 24 hours.

Geomagnetyzm

Geomagnetic conditions globally reached minor storm levels (NOAA Kp 5) between 21:00 UTC on March 03 and 00:00 UTC on March 04. Geomagnetic conditions locally reached minor storm levels (K Bel 5) between 22:00 UTC on March 03 and 01:00 UTC on March 04. The geomagnetic storms are possibly linked to a mild high-speed stream arrival, likely from either SIDC Coronal Hole 152 (northern, positive polarity) or SIDC Coronal Hole 153 (southern, positive polarity). Mostly quiet conditions (NOAA Kp 2), with a small chance of isolated unsettled intervals (NOAA Kp 3), are expected over the next 24 hours.

Poziomy przepływu protonów

The greater than 10 MeV proton flux was below the 10 pfu threshold during the last 24 hours. It is expected to remain below the threshold level over the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux measured by GOES 18 was above the 1000 pfu threshold between 15:30 UTC and 22:30 UTC on March 03. The greater than 2 MeV electron flux measured by GOES 19 was above the 1000 pfu threshold between 14:00 UTC and 18:45 UTC on March 03. The greater than 2 MeV electron flux is expected to be below the 1000 pfu threshold over the next 24 hours. The 24-hour electron fluence was at moderate levels but it is expected to decrease to normal levels over the next 24 hours.
