Highlights of Solar and Geomagnetic Activity
13 - 19 May 2019
Solar activity was at very low to low levels, with low-level
activity observed on 15 May due to a C2.0/SN flare from Region 2741
(N05 L=272, class/area Hsx/160 on 15 May). Very low-level activity
was observed for the remainder of the period. Two eruptions were
observed in coronagraph imagery, but were directed east and
determined to not be geoeffective.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at
high levels on 13, 15, and 16 May. Normal to moderate levels were
observed for the remaining days in the period.
Geomagnetic field activity reached G3 (Major) storm levels on 14 May
due to effects from a CME that erupted on 11 May. G3 storm
conditions were observed during the 14/0600-0900 UTC synoptic
period, with G2 stom conditions occurring in the 14/0300-0600 UTC
period. Active conditions occurred in the 14/0900-1200 and
14/1800-2100 UTC periods. Solar wind parameters at the DSCOVR
spacecraft were enhanced with Bt reaching as high as 15 nT
accompanied by prolonged periods of southward Bz. Solar wind speed
reached a maximum of 568 km/s. Unsettled conditions were observed on
16-17 May. Quiet conditions were observed for the remainder of the
summary period.
Forecast of Solar and Geomagnetic Activity
20 May - 15 June 2019
Solar activity is expected to be very low levels throughout the
period.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at high levels on 21-24 May and 29 May - 02 June due
to coronal hole high speed stream effects. Normal to moderate levels
are expected for the remainder of the period.
Geomagnetic field activity is expected to be at active levels on 29
May due to recurrent coronal hole activity. Quiet to unsettled
levels are expected for the remainder of the period.
