Solaktivitet

Sammanfattning av de senaste 24 timmarna
Solar activity was very low. Region 2680 (N08W46, Hsx/alpha) remained inactive. No Earth-directed CMEs were visible in available coronagraph imagery.
Prognos
Solar activity is expected to remain very low over the next three days (19-21 Sep).

Energirika partiklar

Sammanfattning av de senaste 24 timmarna
The greater than 2 MeV electron flux was at moderate to high levels with a maximum flux of 31,067 pfu at 18/1655 UTC. The greater than 10 MeV proton flux was at background values.
Prognos
The greater than 2 MeV electron flux is expected to continue at high levels the next three days (19-21 Sep), with a chance for very high levels, due to CH HSS influences. The greater than 10 MeV proton flux is expected to continue at background levels all three days.

Solvind

Sammanfattning av de senaste 24 timmarna
Solar wind parameters were indicative of continued CH HSS influences. Total field strength ranged primarily from 3 to 5 nT. The Bz component was variable. Solar wind speeds gradually declined from speeds near 675 km/s to 500 km/s by periods end. The phi angle was primarily positive.
Prognos
Solar wind speed is expected to remain elevated all three days (19-21 Sep), but decline as the influence of the extension of the north polar, positive polarity CH HSS wanes.

Geospace

Sammanfattning av de senaste 24 timmarna
The geomagnetic field was quiet to unsettled.
Prognos
The geomagnetic field is expected to be quiet to unsettled, with a few isolated active periods likely on days one and two (19-20 Sep). Day three (21 Sep) is expected to be at quiet to unsettled levels as CH HSS influences wane.
Enligt den aktuella datan finns det ingen chans för norrsken på medelhöga breddgrader
Solvindens hastighet är för närvarande måttlig hög (500,7 km/sec.)
