Solar Activity

.24 hr Summary...
Solar activity remained low. Region 3734 (N07E60, Dso/beta) produced the
strongest flare of the period, a C5.7 flare at 29/1538 UTC. Region 3729
(S05E20, Eai/beta) remained the most complex on the visible disk. The
other 13 spotted numbered regions were either stable or displayed only
minor evolutions. No

A large (~30 degree) filament centered near S28W18 lifted-off at around
29/1430 UTC. The associated CME, seen in LASCO C2 imagery off the SW at
29/1600 UTC, is likely to result in a glancing-blow on 03 Jul.

.Forecast...
Solar activity is expected to be low over 30 Jun-02 Jul with a chance
for M-class (R1/R2-Minor/Moderate) events.

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux was at normal to moderate levels
and the greater than 10 MeV proton flux was steady at background levels.

.Forecast...
The greater than 2 MeV electron flux is expected to be at normal to
moderate levels over 30 Jun-02 Jul. The greater than 10 MeV proton flux
is expected to persist at background levels through 02 Jul.

Solar Wind

.24 hr Summary...
The solar wind environment remained slightly enhanced this period
following CME passage on 28 Jun. Total field strength ranged 6-11 nT and
Bz varied between +/-8 nT. Solar wind speeds were mostly between 400-500
km/s. Phi was predominately positive.

.Forecast...
Slightly enhanced solar wind conditions are expected to persist over 30
Jun. An additional enhancement is expected over 01-02 Jul due to the
anticipated arrival of CMEs from 26-27 Jun.

Geospace

.24 hr Summary...
The geomagnetic field ranged from quiet to unsettled levels.

.Forecast...
Quiet to unsettled conditions are expected to prevail over 30 Jun.
Unsettled to active conditions are expected on 01-02 Jul due to the
anticipated arrival/passage of CMEs from 26-27 Jun.
