Solar Activity

.24 hr Summary...
Solar activity remained at low levels. Region 2376 (N13E52,
Eao/beta-gamma) produced a pair of C1 flares at 30/1243 UTC and 30/2211
UTC, respectively. The region exhibited slight growth in its leader
portion. Region 2373 (N17E32, Dao/beta) underwent some minor growth in
its trailer spots, but was inactive and remained in a fairly stable
bipolar configuration. The remainder of the disk and limb was quiet and
stable. No Earth-directed coronal mass ejections were observed on
available LASCO imagery.

Solar activity is expected to be low with a slight chance for M-class
(R1-R2/Minor-Moderate) flare activity for days one through three (01 -
03 Jul) primarily due to the slightly higher flare potential of Region

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux reached high levels this period
with a peak flux of 9,667 pfu observed at 30/1725 UTC. The greater than
10 MeV proton flux returned to background levels.

The greater than 2 MeV electron flux is expected to persist at moderate
to high levels over the next three days (01 - 03 Jul). 10 MeV proton
flux is expected to remain at background levels over days one through
three (01 - 03 Jul).

Solar Wind

.24 hr Summary...
Solar wind parameters were at ambient conditions. Solar wind speeds
generally ranged between about 360 to 385 km/s with a gradual increase
to near 435 km/s by periods end. IMF total field strength ranged
between 1-6 nT while the Bz component varied between +3 nT to -4 nT. The
phi angle was in a predominately positive (away) solar sector with
negative (towards) orientation observed from about 30/1400-2100 UTC.

Solar wind parameters are expected to remain mostly nominal on days one
through three (01 - 03 Jul). A minor enhancement may be reflected from
the influence of a small positive polarity coronal hole late on day one
(01 Jul).


.24 hr Summary...
The geomagnetic field was at quiet to unsettled levels throughout the

The geomagnetic field is expected to be mostly quiet on days one through
three (01 - 03 Jul). Isolated periods of unsettled activity are possible
in response to a small positive polarity coronal hole on day one (01
Jul). is the U.S. government's official web portal to all federal, state and local government web resources and services.
