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.

USAF/NOAA rapport för sol- och geofysisk aktivitet

SDF Nummer 134 publicerat klockan 2200Z på 14 May 2003

IA. Analys av solfläcksgrupper och solaktivitet från 13-2100Z till 14-2100Z

Solar activity was very low. Region 360 (at S04 W19) was numbered.
IB. Prognos för solaktivitet
Solar actvity is expected to be very low to low for the next 24 hours. Two new active regions on the east limb (returning Regions 336 at latitude N13 and 337 at S12) may become the source of isolated C-class flares in the following days.
IIA. Sammanfattning av geofysisk aktivitet 13-2100Z till 14-2100Z
The geomagnetic field has been at unsettled to minor storm levels due to high speed solar wind streams from a favorably positioned coronal hole. 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 at unsettled to minor storm levels for the next day, falling off to unsettled to active on days two and three. The coronal hole causing high speed solar wind streams is rotating out of 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. Beginning 1500 UT on May 15, GOES-8 will once again become 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.
