Highlights of Solar and Geomagnetic
Activity 29 May - 04 June 2017
Solar activity was at very low levels on
29-30 May and again on 04
June. Low levels were reached from 31 May-03 June
due to flare
activity from Region 2661 (N06, L=211, class/area Dao/200 on
02
June). The largest flare of the period was a C8/Sn at 02/1757
UTC.
Other activity included an approximate 28 degree filament
eruption
centered near S11E19 observed lifting off in H-alpha
imagery
beginning at 30/1300 UTC. An associated faint, narrow CME
was
observed off the southeast limb beginning at 30/2334 UTC.
No
proton events were observed at geosynchronous orbit.
The greater than 2
MeV electron flux at geosynchronous orbit was at
normal to moderate levels.
Geomagnetic field activity ranged from quiet to active levels.
The
period began under the continued influence of the 23 May CME.
Total
field reached a maximum of 17 nT at 29/0900 UTC followed by
a
decrease to around 8 nT by 29/1600 UTC. The Bz component deflected
south
to a maximum of -13 nT at 29/1230 UTC. Solar wind increased
from
approximately 350 km/s at the beginning of the period to a
maximum of 561
km/s at 30/0940 UTC and slowly declined thereafter.
The geomagnetic field
responded with quiet to active conditions on
29-30 May. A return to near
nominal solar wind conditions followed
on 31 May-02 June. Quiet conditions
were observed on 31 May and 02
June with quiet to unsettled levels observed
on 01 June. At
approximately 03/0615 UTC, total field, solar wind speed,
density,
and temperature began to increase due to the possible arrival of
the
30 May CME combined with a positive polarity coronal hole high
speed
stream (CH HSS). Total field increased to 14 nT at 03/1125 UTC
while
the Bz component deflected south to -13 nT. Solar wind
speed
increased to near 500 km/s at 03/1825 UTC before slowly
recovering
by the end of the period. The geomagnetic field responded with
quiet
to active levels on 03 June followed by quiet conditions on 04 June.
FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY 05 JUNE - 01 JULY
2017
Solar activity is expected to be at very low to low levels
from
05-12 June as Region 2661 transits across the visible disk. Very
low
levels are expected from 13 June-01 July.
No proton events are
expected at geosynchronous orbit.
The greater than 2 MeV electron flux at
geosynchronous orbit is
expected to be at normal to moderate levels with high
levels likely
from 16-26 June due to recurrent CH HSS influence.
Geomagnetic field activity is expected to be mostly quiet
with
unsettled to active levels expected on 14-19 June and G1
(Minor)
geomagnetic storm levels likely on 16 June due to recurrent CH
HSS
effects.
