Päikese aktiivsed piirkonnad ja pursked

The solar flaring activity was at low levels. There are currently seven numbered regions on the solar disk, including newly numbered region NOAA 3468 on the south west limb. The largest flare was a C3.9 flare, peaking at 16:33 UTC on October 15, associated with NOAA AR 3464. This region along with NOAA AR3468 were the most active over the period. NOAA AR 3460 is about to rotate off the disk. The remaining regions were mostly stable and quiet. The solar flaring activity is expected to be at low levels over the next 24 hours with C-class flares likely and a low chance for isolated M-class flares.

Krooniaine massiline väljavool

There were no Earth-directed Coronal Mass Ejections (CMEs) detected in the available coronagraph observations.

Krooniauk

A small negative polarity coronal hole near the equator began to cross the central meridian on October 16.

Päikesetuul

The solar wind parameters reflected a return to a slow solar wind regime The interplanetary magnetic field ranged between 0 and 4 nT. Bz had a minimum value of -2 nT. The solar wind speed decreased further from 430km/s to 330 km/s. The interplanetary magnetic field orientation was predominantly in the negative sector (field directed towards the Sun). The solar wind parameters are expected to reflect nominal conditions for the next days, with possible slight enhancements from October 18 due to coronal hole influences.

Geomagnetism

During last 24 hours the geomagnetic conditions were at quiet to unsettled levels (NOAA Kp 1-2, K Bel 1-3). Geomagnetic conditions are expected to be at quiet levels.

Prootoni voo tasemed

Over the past 24 hours the greater than 10 MeV GOES proton flux was at nominal levels and is expected to remain so over the next days.

Elektronivoog geostatsionaarsel orbiidil

The greater than 2 MeV electron flux remained below the 1000 pfu threshold as measured by GOES 16. It is expected to remain below this threshold over the next days. The 24 hour electron fluence was at nominal levels. The electron fluence is expected to be at nominal levels for the next days.
