Highlights of Solar and Geomagnetic
Activity 13 - 19 June 2016
Solar activity was at very low levels the
majority of the period
with low levels observed on 13 and 19 June due to a C3
flare at
13/0552 UTC from Region 2552 (N15, L=359, class/area Dao/150 on
11
June) and a C1 flare at 19/1158 UTC from Region 2558 (N13,
L=215,
class/area Cso/030 on 19 June). The majority of the B-class
activity
was caused by Region 2555 (S09, L=274, class/area Cao/080 on
17
June). No Earth-directed coronal mass ejections were observed
during
the period.
No proton events were observed at geosynchronous
orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was
at
normal to moderate levels throughout the period and briefly
reached
high levels on 19 June with a maximum flux of 1,030 pfu at
19/1640
UTC.
The geomagnetic field ranged from quiet to G2-Moderate
storm levels.
Solar wind conditions began the period under a waning
positive
polarity coronal hole high speed stream (CH HSS). Solar wind
speeds
decreased from approximately 620 km/s to around 420 km/s by
midday
on 14 June. Total field decreased from 8 nT to 4 nT. By late on
14
June, total field increased to 15 nT with the Bz component
mostly
southward near -14 nT while solar wind increased to a maximum of
772
km/s at 15/0410 UTC, indicative of a co-rotating interaction
region
followed by another positive polarity CH HSS. The geomagnetic
field
responded with quiet to active levels on 13 June, quiet
to
G2-Moderate storm levels on 14 June and quiet to G1-Minor storm
levels
on 15 June. By early on 16 June, total field decreased to
around 6 nT with
solar wind speeds in the 500-600 km/s range. These
conditions continued until
19 June when solar wind speeds decreased
to nominal levels. Quiet conditions
were observed on 16 and 19 June
with quiet to unsettled levels on 17-18 June.
FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY 20 JUNE - 16 JULY
2016
Solar activity is expected to be at very low to low levels for
the
forecast period.
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
on
20-22 June, 26 June-01 July, 04-07 July and again on 16 July due
to CH HSS
activity.
Geomagnetic field activity is expected to be at unsettled to
active
levels from 23-27 June, 02-03 July, 07-12 July and 14-15
July.
G1-Minor storm levels are likely on 02-03 July and 11 July due
to
recurrent CH HSS activity.
