Güneş Aktif Bölgeleri ve parlama

A total of 8 numbered sunspot groups were identified on the disk over the past 24 hours. Six M-class flares were observed in the last 24 hours, from three different active regions. The largest flare was a M2.2 flare (SIDC Flare 6919) peaking on February 05 at 19:34 UTC, which was produced by SIDC Sunspot Group 783 (NOAA Active Region 4362). SIDC Sunspot Group 784 (NOAA Active Region 4366) currently located at N13W19 remains the most complex and largest region visible, although it has stopped growing. More M-class flares are very likely in the next 24 hous, and X-class flares are still possible.

Koronal Kütle Atılımı

A partial-halo CME was observed in LASCO C2 starting at 23:24 UTC on 5 February, with an angular width of approximately 200 degrees and most of the material directed toward the northeast. This CME is backsided and is not expected to reach Earth. Earlier on 5 February, LASCO C2 observed a CME at 15:48 UTC associated with an M1.8 flare from SIDC Sunspot Group 783 (NOAA Active Region 4362), currently located at S18W21. A second CME from the same active region, associated with an M2.2 flare, was detected at 20:00 UTC. Both CMEs are faint, slow, and directed primarily southward, and are therefore not expected to affect Earth.

Koronal delikler

SIDC Coronal Hole 136 (equatorial coronal hole with a negative polarity) is on the western hemisphere. SIDC Coronal Hole 142 (mid-latitude coronal hole with a negative polarity) is higher in latitude and has just crossed the central meridian.

Güneş rüzgarı

The solar wind at Earth has remained at elevated speeds, near 600 km/s, in the wake of the ICME that arrived on 4 February and under the influence of a high-speed stream from SIDC Coronal Hole 136 with negative polarity (towards the Sun). The interplanetary magnetic field is around 7 nT, with a positive Bz component. A gradual decrease toward a slow solar- wind regime is expected over the next 24 hours.

Jeomanyetizma

Geomagnetic conditions have been quiet to unsettled in the last 24 hours (Kp and K_Bel up to 3). Similar conditions, with possible active periods, can be expected for the next 24 hours.

Proton akı seviyeleri

The greater than 10 MeV proton flux remained below the 10 pfu threshold in the last 24 hours. A warning condition has been issued for the next 24 hours due to the high solar activity.

Jeostatik yörüngedeki elektron akıları

The greater than 2 MeV electron flux as measured by GOES 18 and GOES 19 has been below the 1000 pfu threshold for the last 24 hours. Similar conditions can be expected for the next 24 hours. The 24-hour electron fluence was at normal levels and is expected to remain so.
