Güneş Aktif Bölgeleri ve parlama

Solar flaring activity was low over the past 24 hours, with only a C1.5 flare from the west limb (SIDC 7062) peaking at 16:41 UTC on February 22. There is currently one numbered active region on the solar disk, SIDC Sunspot Group 799 (magnetic type beta), which has emerged in the southeast quadrant. The solar flaring activity is expected to be low over the next 24 hours, with C-class flares unlikely.

Koronal Kütle Atılımı

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

Güneş rüzgarı

Over the past 24 hours, the solar wind parameters (ACE) continue to reflect the ongoing influence of the high-speed stream associated with the recurrent, negative polarity, equatorial, coronal hole (SIDC Coronal Hole 147). Speed values ranged between 580 km/s and 740 km/s. The interplanetary magnetic field values were between 4 nT and 10 nT. The Bz component varied between -9 nT and 9 nT. The interplanetary magnetic field angle was mostly in the negative sector. Mostly enhanced solar wind conditions are expected over the next 24 hours due to the continuous influence of the high-speed stream from the negative polarity coronal hole (SIDC Coronal Hole 147).

Jeomanyetizma

Geomagnetic conditions globally were mostly at unsettled to active levels (NOAA Kp 3 to 4), with two intervals of minor storm conditions (NOAA Kp 5- to 5) between 21:00 UTC on February 22 and 00:00 UTC on February 23 and between 03:00 UTC and 06:00 UTC on February 23. Geomagnetic conditions locally were mostly at unsettled to active levels (K BEL 3 to 4), with an interval of minor storm conditions (KBEL 5) between 21:00 UTC on February 22 and 01:00 UTC on February 23. Unsettled to minor storm conditions are expected over the next 24 hours due to the continuous influence of the high-speed stream from the negative polarity coronal hole (SIDC Coronal Hole 147).

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 19 was below the 1000 pfu threshold in the last 24 hours. The greater than 2 MeV electron flux measured by GOES 18 exceeded the 1000 pfu threshold between 19:30 UTC on February 22 and 02:00 UTC on February 23 and remained below the threshold for the rest of the last 24 hours. The greater than 2 MeV electron flux is expected to remain around the 1000 pfu threshold 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.
