Green slow moving aurora photographed with SLR type camera. Only very faintly visible to eye, for 3 hours from a beach near Invercargill NZ. Kp was about 4 during this time.

.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).

.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).

.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.
