Güneş Aktif Bölgeleri ve parlama

A total of 4 numbered sunspot groups were identified on the disk over the past 24 hours, with simple alpha or beta magnetic field configuration. There was only one C-class flare in the last 24 hours. This was a C1.2 flare from SIDC Sunspot Group 842 (NOAA AR 4414), currently located at N15E12 with a Beta magnetic configuration. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares likely.

Koronal Kütle Atılımı

No Earth-directed CMEs were observed int he last 24 hours.

Koronal delikler

There are two mid-latitude positive polarity coronal holes (SIDC Coronal Holes 154 and 158) in the western hemisphere, and one (159) crossing the central meridian, also with positive polarity.

Güneş rüzgarı

The solar wind speed is low, around 420 km/s with interplanetary magnetic field magnitude of 6 nT, with positive polarity (away from the Sun). In the next 24 hours, there is a possible arrival of a mild fast solar wind stream from the small positive polarity coronal holes (SIDC Coronal Holes 154 and 158).

Jeomanyetizma

Geomagnetic conditions have been quiet to unsettled (Kp up to 2 and K_BEL up to 3). Similar conditions can be expected for the next 24 hours, with possible active to minor storm periods if the fast solar wind from SIDC Coronal Holes 154 and 158 arrives to the Earth.

Proton akı seviyeleri

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 for the next 24 hours.

Jeostatik yörüngedeki elektron akıları

The greater than 2 MeV electron flux, as measured by GOES-19, remained below the 1000 pfu alert threshold over the past 24 hours. The greater than 2 MeV electron flux, as measured by GOES-18, briefly exceeded the 1000 pfu alert threshold between 17:00 UTC and 23:00 UTC on April 12 and remained below the threshold for the rest of the period. The flux is expected to remain mostly below the alert threshold over the next 24 hours. The 24-hour electron fluence was at normal to moderate levels over the past 24 hours and is expected to remain at these levels over the next 24 hours.
