Highlights of Solar and Geomagnetic
Activity 03 - 09 July 2017
Solar activity ranged from very low to
moderate levels. The period
began on 03 Jul with an M1 flare (R1-Minor)
observed at 03/1615 UTC
from an emerging region on the west limb. A CME was
associated with
the M1 flare, but was determined to be well off the Sun-Earth
line.
Low levels were observed on 04 Jul due to a single C1 flare
observed
at 04/0425 UTC from this same unnumbered region. Very low
levels
were recorded on 05-06 Jul. Activity increased to low levels on
07
and 08 Jul as new Region 2665 (S06, L=111, class/area Ekc/710 on
09
Jul) produced a C1 flare observed at 07/1349 UTC. This was followed
by
a C3/Sf flare observed at 08/2353 UTC from the same region.
Activity levels
increased to moderate as developing Region 2665
produced an impulsive M1/2n
flare (R1-Minor) observed at 09/0318
UTC. Additional C-class flares were
observed from Region 2665
throughout the remainder of 09 Jul.
No
proton events were observed at geosynchronous orbit.
The greater than 2
MeV electron flux at geosynchronous orbit was at
normal levels throughout the
period.
Geomagnetic field activity was at quiet to isolated unsettled
levels
from 03-08 Jul. During this time, the solar wind environment was
at
nominal levels with the phi angle in a steady negative orientation.
By
early on 09 Jul, solar wind parameters reflected the onset of a
CIR in
advance of a recurrent, positive polarity CH HSS. The
geomagnetic field
responded with active to minor storm levels
(G1-Minor) throughout 09 Jul.
Solar wind speed increased from near
365 km/s to a maximum of 602 km/s at
09/2103 UTC. Total field ranged
from 4-14 nT while the Bz component varied
between +/-11 nT. Phi
angle rotated from a negative to a mostly positive
sector after
09/0430 UTC.
FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY
10 JULY - 05 AUGUST 2017
Solar activity is expected to be at low levels
throughout the
outlook period. A chance for additional M-class activity
(R1-R2,
Minor-Moderate) is possible from 10-30 Jul.
No proton events
are expected at geosynchronous orbit.
The greater than 2 MeV electron
flux at geosynchronous orbit is
expected to reach high levels on 10-15 Jul
with normal to moderate
levels expected throughout the remainder of the
outlook period.
Geomagnetic field activity is expected to be at
generally quiet to
unsettled levels for a majority of the outlook period.
Unsettled to
active conditions are likely on 10 Jul with active to minor
storm
levels (G1-Minor) likely on 05 Aug due to the influence of
a
recurrent, positive polarity CH HSS.
