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 16 2200 UTC
Prepared by the NOAA © SWPC and processed by SpaceWeatherLive.comJoint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 167 Issued at 2200Z on 16 Jun 2002
IA. Analysis of Solar Active Regions and Activity from 15-2100Z to 16-2100Z
Solar activity was low. The most notable event of the
period was a long duration C1.0 flare at 16/0814 UTC. There were no
optical reports associated with this event, but a CME was evident in
LASCO imagery just following the flare, from a presumed source
behind the northeast limb, near N35. Active prominences have been
visible in H-alpha imagery in this area for the past 24 hours.
Other activity included an optically uncorrelated C1.4 flare at
16/0332 UTC. B-class activity was observed in Region 9991 (S21W47)
and Region 3 (N00E49). New Region 5 (N13E74) rotated into view and
was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to remain
mostly low for the next three days.
IIA. Geophysical Activity Summary 15-2100Z to 16-2100Z
The geomagnetic field was quiet to unsettled.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to persist at quiet to unsettled levels for the next three
days.

This message is for users of the NOAA/SEC Space
Weather Operations sunspot region numbers. As you
may have noticed, we are steadily approaching
region number 10000. The plan for Space Weather
operations is to go 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 IUWDS
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 regions numbers 10000 and higher.
