.24 hr Summary…
Solar activity was low. The largest solar event of the period was a C1
flare from Region 2480 (N02E65, Dao/beta). The region continued to
develop as it rotated further onto the solar disk, exhibiting penumbral
coverage around the trailer spot as well as developing new intermediate
spots. Region 2477 (N11E89, Hax/alpha) displayed the onset of some
separation in its singular spot. Several different areas of pours were
noted and are being monitored for further development.

Several eruptions were observed in SOHO/LASCO coronagraph imagery over
the past 24 hours. The most prominent was an eruption from around the SW
limb, near old Region 2473, creating a partial halo signature first seen
in C2 imagery beginning at 06/1412 UTC. A filament eruption around the
same time was observed lifting off the SE limb around 06/1200 UTC. Both
events were analyzed and not expected to cause impacts to Earth.

Another eruption in the corona was observed in SDO AIA193 imagery
beginning around 06/1241 UTC near Region 2477. Activity from previous
eruptions still being present in coronagraph imagery caused difficulty
in analyzing an associated coronal mass ejection (CME) signature. The
subsequent model run suggested a glancing blow is possible around 09
Jan.

.Forecast…
Solar activity is expected to be very low with a chance for C-class
flares over the next three days (07-09 Jan).

6th January 2016

.24 hr Summary…
Solar activity was low. Region 2476 (S08W07, Cro/beta) continued its
gradual decay. Region 2477 (N12E15, Hsx/alpha) remained stable over the
past 24 hours. An impulsive C1 flare was observed from a region rotating
around the NE limb at 06/1137 UTC. A filament centered around the the SE
limb began erupting around 06/1100 UTC. No Earth-directed coronal mass
ejections (CMEs) were observed in available coronagraph imagery.

.Forecast…
Solar activity is expected to be very low with a slight chance for
C-class flares over the next three days (06-08 Jan).

5th January 2016

.24 hr Summary…
Solar wind parameters, as measured by the ACE spacecraft, reflected
mostly nominal conditions for the majority of the day with a minor
enhancement towards the end of the period. Total magnetic field strength
(Bt) was around 5-8 nT for most of the period. After 05/0800 UTC there
was a gradual increase to a peak of 11 nT. The Bz component of the
magnetic field was predominantly northward. Wind speeds underwent a
decline with winds beginning the period around 450 km/s and trending
downward to around 370 km/s before increasing to above 420 km/s by the
period’s end. Phi angle was oriented in the positive sector (away from
the Sun).

.Forecast…
Solar wind parameters are expected to remain near background levels on
day one (05 Jan) under a mostly nominal solar wind regime. A solar wind
enhancement is expected on day two (06 Jan) due to the onset of a
co-rotating interaction region (CIR) followed by the influence of a
positive polarity CH HSS. Wind speeds in excess of 650 km/s were
observed from this HSS last rotation. On day three (07 Jan), CH HSS
effects are expected to persist.

5th January 2016

.24 hr Summary…
Solar activity was very low. Region 2476 (S09E12, Dao/beta) was the most
complex spot group on the solar disk. The region underwent gradual
dissipation around the leader and trailer spots over the past 24 hours.
Region 2477 (N34E27, Hsx/alpha) was the only other spotted region. It
remained relatively inactive.

A disappearing solar filament (DSF) was observed in SDO/AIA 304 imagery
lifting off from the southeast quadrant at approximately 04/1230 UTC.
The material appeared to be reabsorbed and there is no anticipated
geoeffective component associated with this event. There were no
Earth-directed coronal mass ejections (CMEs) observed in available
satellite imagery during the period.

.Forecast…
Solar activity is expected to be very low with a chance for C-class
flares over the next three days (05-07 Jan).

3rd January 2016

.24 hr Summary…
Solar wind parameters were nominal. Solar wind speeds were relatively
steady between 425-500 km/s. Total field strength values varied between
6-9 nT and Bz was mostly northward throughout the period. The phi angle
remained steady in a positive (away) solar sector orientation.

.Forecast…
Solar wind parameters are expected to become enhanced mid-to-late on day
one (03 Jan) with the anticipated arrival of the 01 Jan CME. Solar wind
measurements are expected to begin a return to near-background levels
early on day two (04 Jan) as CME effects subside.

3rd January 2016

.24 hr Summary…
Solar activity was very low and no solar flares were observed this
period. Region 2476 (S10E41, Cao/beta) exhibited minor growth
throughout the period while the remaining active regions were stable.

An eruptive prominence on the limb was observed near S38W90 in SDO/AIA
304 imagery between 03/0930-1030 UTC. The eruption propagated along the
filament channel from southeast to northwest and while relevant
coronagraph imagery was unavailable at the time of this writing, this
event is not expected to be Earth-directed.

.Forecast…
Solar activity is expected to be very low with a chance for C-class
flares over the next three days (03-05 Jan).
