Solar activity report
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.
Report of Solar-Geophysical Activity 2002 Jun 29 2200 UTC
Prepared by the NOAA © SWPC and processed by SpaceWeatherLive.comJoint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 180 Issued at 2200Z on 29 Jun 2002
IA. Analysis of Solar Active Regions and Activity from 28-2100Z to 29-2100Z
Solar activity was at low levels. Multiple low
level C- and B-class flares occurred, none of which were optically
correlated. Region 8 (S10W69) continues to show very gradual decay
in penumbral coverage and has been stable throughout the period.
Region 11 (S11W32) changed little from yesterday. Regions 18
(N15W73) and 19 (S17E72) were assigned today.
IB. Solar Activity Forecast
Solar activity is expected to be at
low levels.
IIA. Geophysical Activity Summary 28-2100Z to 29-2100Z
The geomagnetic field activity was at quiet to unsettled levels.
IIB. Geophysical Activity Forecast
The geomagnetic field activity
is expected to be at quiet to unsettled levels. Day one may see
mostly unsettled conditions due to the effects of the partial-halo
coronal mass ejection (CME) that occurred on 27 June.

This message is for users of the NOAA/SEC Space
Weather Operations sunspot region numbers. As you
may have noticed, region number 10000 was assigned
on June 14. Space Weather operations is going
through the sequence of Region numbers as 9998,
9999, 0000, 0001, and so on. SEC's product text
discussions of the active regions will ignore the
leading zeroes (for example, we will say 'Region
number 5' rather than Region number '0005'). However,
the Geoalert product, the Region Report product, as
well as the USAF and ISES data exchange codes will
preserve the 4 digit format. The necessity of using
four digits is for operational purposes only. For
historical purposes all regions beyond Region 9999
will be understood to be in a series of region numbers
10000 and higher.
