Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was low over the past 24 hours, with several C-class flares recorded. The largest flare was a C9.0 flare (SIDC Flare 7927), peaking at 08:28 UTC on June 11, associated with SIDC Sunspot Group 870 (NOAA Active Region 4465; magnetic type beta- gamma). There are currently five numbered active regions on the visible solar disk. SIDC Sunspot Group 870, which remains the most complex active region on the solar disk, was the main driver of the flaring activity observed over the past 24 hours. Low flaring activity was also produced by SIDC Sunspot Group 884 (NOAA Active Region 4456), which has now fully rotated behind the west limb, and by active region from behind the east limb. The remaining active regions are relatively simple (magnetic type alpha or beta) and did not produce any significant flaring activity. Solar flaring activity is expected to remain low over the next 24 hours, with C-class flares very likely and a chance of M-class flares.

Koronalny wyrzut masy

A halo coronal mass ejection (SIDC CME 675) was detected in SOHO/LASCO-C2 data from 00:36 UTC on June 11. The CME was directed primarily towards the northeast from Earth's perspective and was associated with a long-duration C6.7 flare (SIDC Flare 7923), peaking at 00:02 UTC on June 11, produced by SIDC Sunspot Group 870 (NOAA Active Region 4465), as well as with Type II and Type IV radio emissions detected at 00:13 UTC and 00:28 UTC on June 11, respectively. Associated coronal dimming and an EUV wave were also observed in SDO/AIA data. The bulk of the ejecta is expected to miss Earth, although a glancing blow could be possible on June 13. Follow up analysis indicated that the CMEs reported yesterday, SIDC CME 673 and SIDC CME 674, first observed in SOHO/LASCO-C2 from around 16:36 UTC and 21:36 UTC on June 9, respectively, may also result in glancing blows at Earth around June 13, although confidence remains low.

Wiatr słoneczny

Over the past 24 hours, solar wind parameters (SOLAR-1 and DSCOVR) reflected near slow solar wind conditions. The solar wind speed ranged between 360 and 400 km/s. The interplanetary magnetic field remained below 6 nT, later increasing to values up to 10 nT. The magnetic field orientation was predominantly in the positive sector (field directed away from the Sun). Solar wind conditions are expected to become slightly elevated over the next 24 hours due to the expected arrival of a high-speed stream from the negative polarity coronal hole SIDC Coronal Hole 147, with a chance of a weak enhancement from late on June 13 due to possible glancing blows from the June 9 and June 11 CMEs (SIDC 673-675).

Geomagnetyzm

Geomagnetic conditions were quiet to unsettled both globally and locally over Belgium (NOAA Kp = 1 to 3; K-Bel = 1 to 3). Mostly quiet to unsettled geomagnetic conditions are expected over the next hours. From late on June 11, active conditions are expected, with a possible isolated minor to moderate storm interval in response to the arrival of the high- speed stream from a negative polarity coronal hole (SIDC Coronal Hole 147).

Poziomy przepływu protonów

The greater than 10 MeV proton flux, as measured by GOES-18, was below the 10pfu threshold level over the past 24 hours and is expected to remain so over the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by GOES-19, was mostly below the 1000 pfu threshold over the past 24 hours. The greater than 2 MeV electron flux is expected to remain below the 1000 pfu threshold over the next 24 hours. The 24-hour electron fluence was at normal to moderate levels and is expected to be these levels over the next 24 hours.
