Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was moderate over the past 24 hours with 3 M-class flares. The largest flare was a M1.9 flare peaking on October 15 at 02:13 UTC, which was produced by SIDC Sunspot Group 283 (NOAA Active Region 3854).There are currently 8 numbered active regions on the visible disk. The most complex regions are SIDC SGs 281 and 283 (NOAA AR 3852 and 3854) all magnetic type beta-gamma. The solar flaring activity is expected to be at moderate levels over the next 24 hours with C-class flares expected and M-class flares probable and a low chance of X-class flares.

Koronalny wyrzut masy

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

Dziury koronalne

A positive polarity mid-latitude coronal hole (SIDC Coronal Hole 68) continues to cross the central meridian. A high-speed stream from this coronal hole may impact the Earth/enhance the solar wind environment near Earth on October 17.

Wiatr słoneczny

The solar wind at the Earth remained mostly slow over the last 24 hours. The solar wind speed was around 400 km/s and the interplanetary magnetic field was around 7nT. The Bz reached a minimum value of -5 nT. A small shock was observed on October 14 at 17:18 UTC. The interplanetary magnetic field jumped from 6 nT to 9 nT, with the Bz component changing from -2 nT to -4 nT. The solar wind speed jumped from 381 km/s to around 403 km/s. The solar wind density at the shock jumped from 2.62 ppcc to around 6.68 ppcc (ACE). Slow solar wind conditions are expected in the next 24h.

Geomagnetyzm

Geomagnetic conditions were globally and locally quiet to active (Kp 4- and K Bel 3). Quiet conditions are expected in the next 24 hours.

Poziomy przepływu protonów

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

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux remained below the 1000 pfu alert threshold, and is expected to remain below the threshold during the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain so.
