Highlights of Solar and Geomagnetic Activity
12 - 18 January 2015

Solar activity ranged from very low levels to high levels during the
period. The period began at low levels with Regions 2255 (S16,
L=321, class/area Dai/160 on 04 January) and 2260 (N10, L=286,
class/area Cao/070 on 14 January) producing the majority of the
C-class activity. High levels were observed on 13 January with
moderate levels on 14 January as Region 2257 (N07, L=322, class/area
Dki/480 on 09 January) produced the largest flares of the period; an
M5/2b flare at 13/0424 UTC with an associated 290 sfu Tenflare, an
M4 at 13/0458 UTC, and an M2 at 14/1258 UTC. Region 2257 was in
decay from the beginning of the period until it rotated around the
NW limb on 14 January. Solar activity returned to very low to low
levels for the rest of the period. 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 reached
moderate levels from 12-15 January before decreasing to normal
levels for the rest of the period.

Geomagnetic field activity was at mostly quiet to unsettled levels
through the period. Solar wind was in a slow decline through the
period from initial values near 510 km/s to around 320 km/s by the
end of the period. Total field ranged from 5 nT to 10 nT, with a
variable Bz component, and mostly positive phi angle. As a result,
quiet to unsettled levels were observed from 12-17 January with
quiet levels on 18 January. is the U.S. government's official web portal to all federal, state and local government web resources and services.
