Slunečně aktivní oblasti a vzplanutí

Solar flaring activity was low over the past 24 hours with only C-class flares. The largest flare was a C6.6 flare peaking on January 16 at 09:09 UTC, originated from SIDC Sunspot Group 766 (NOAA Active Region 4345). SIDC Sunspot Group 740 (NOAA Active Region 4341) is the most complex active region (Beta-Gamma-Delta). Solar activity is expected to be moderate over the next 24 hours, with C-class flares expected and M-class flares likely.

Vyhazování koronální hmoty

No new Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images.

Koronální díra

SIDC Coronal Hole 146 (a large equatorial coronal hole with a positive polarity) has reached the central meridian. High Speed Stream from this coronal hole is expected to impact earth late on the 18th of Januari.

Solární bouře

Fast solar wind conditions were recorded over the past 24 hours. The solar wind velocity reached 700 km/s, but is currently gradually reducing to 588 km/s. The interplanetary magnetic field reached 13 nT, with the Bz reaching a minimum value of -10 nT. Solar wind conditions are expected to remain enhanced over the next 24 hours.

Geomagnetismus

Over the past 24 hours geomagnetic conditions were mainly unsettled both locally and globally (Kp3, Kbel 3) but with a isolated active period globally (Kp 4-) on 16 Jan 03:00 to 06:00 UTC. Unsettled geomagnetic conditions are expected over the next day.

Úrovně protonového toku

The greater than 10 MeV proton flux remained below the 10 pfu threshold and is expected to remain so over the next days.

Elektronové toky na geostacionární oběžné dráze

The greater than 2 MeV electron flux was above the 1000 pfu threshold until Jan 15 23:55 UTC and has since then dropped below the threshold and is expected to remain so in the upcoming day. The 24h electron fluence was at moderate level and is expected to return to normal level in the next day.
