Solaktivitetsrapport
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.

SDF Nummer 137 publicerat klockan 2200Z på 17 May 2003
IA. Analys av solfläcksgrupper och solaktivitet från 16-2100Z till 17-2100Z
Solar activity has been very low. No new regions were
numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be very
low, with possible increase in activity over the next few days due
to returning regions emerging from the east limb.
IIA. Sammanfattning av geofysisk aktivitet 16-2100Z till 17-2100Z
The geomagnetic field has been at quiet to unsettled levels. The
greater than 2 MeV electron flux at geosynchronous orbit reached
high levels today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be unsettled on day one, with active conditions possible
on days two and three of the period due to a coronal hole passing
into geoeffective position.

VII. Comments
The GOES 10 energetic proton detectors are showing intermittent, high noise levels in the higher energy proton channels (greater than about 80 MeV). This problem was first noticed in data taken April 26, 2003. To ensure continued operational monitoring of important energetic particle data, it is necessary to reassign primary/secondary designations for the GOES Space Environment Monitor (SEM) detectors. As of 1500 UT on May 15, GOES-8 became the primary satellite for protons. GOES 12 will be the primary satellite for magnetometer, X-ray, and electron measurements. GOES 10 will be the secondary satellite for all SEM sensors - magnetometer, X-ray sensor, and energetic particle sensor. This short-term solution (approximately 2 - 3 months) will be in place until we define and implement a permanent fix. A more detailed explanation can be found at: http://www.sec.noaa.gov/GOES.html.
