Güneş Aktif Bölgeleri ve parlama

Solar flaring activity was high over the past 24 hours, with one M-class flare. The strongest flare was an M5.7 flare (SIDC Flare 7671), peaking at 13:39 UTC on May 10, which was associated with the returning SIDC Sunspot Group 825 (NOAA Active Region 4436, magnetic type beta), located in the northeast quadrant. There are currently five numbered active regions on the solar disk. SIDC Sunspot Group 860 (NOAA Active Region 4432) is the most complex group with magnetic type beta-gamma. The solar flaring activity is expected to be moderate over the next 24 hours, with M-class flares likely and a small chance for X-class flares.

Koronal Kütle Atılımı

A partial halo Coronal Mass Ejection (SIDC CME 650) was observed in LASCO/C2 and C3 coronagraph imagery starting from around 13:48 UTC on May 10. The CME is associated with the M5.7 flare (SIDC Flare 7671) peaking at 13:39 UTC on May 10. Preliminary analysis suggests that the bulk of the CME has a fitted speed around 1300 km/s. While the bulk of the ejecta appears to be directed eastward, a glancing blow at Earth from early UTC on May 13 cannot be excluded. Further analysis is ongoing. No other Earth-directed CMEs were observed in the available coronagraph imagery.

Güneş rüzgarı

Over the past 24 hours, the solar wind parameters (ACE) reflected mostly slow solar wind conditions. Speed values ranged between 360 km/s and 440 km/s. The interplanetary magnetic field values were between 3 nT and 6 nT. The Bz component varied between -4 nT and 5 nT. The interplanetary magnetic field angle was mostly in the positive sector. Mostly slow solar wind conditions are expected over the next 24 hours, with a small chance for a mild high-speed stream influence from the small mid- latitude positive polarity coronal hole (SIDC Coronal Hole 161), which crossed the central meridian on May 9.

Jeomanyetizma

Geomagnetic conditions globally and locally were mostly at quiet levels (NOAA Kp 1 to 2, K BEL 1 to 2). Mostly quiet geomagnetic conditions are expected over the next 24 hours, with a small chance for isolated unsettled to active intervals due to a possible mild high-speed stream influence from SIDC Coronal Hole 161.

Proton akı seviyeleri

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

Jeostatik yörüngedeki elektron akıları

The greater than 2 MeV electron flux measured by GOES 18 and GOES 19 was below the 1000 pfu threshold in the last 24 hours. 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 is presently at normal levels and is expected to remain so over the next 24 hours.
