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 092 publicerat klockan 2200Z på 02 Apr 2003

IA. Analys av solfläcksgrupper och solaktivitet från 01-2100Z till 02-2100Z

Solar activity was at low levels. There were 4 minor C-class flares from Regions 321 (N07W40) and 324 (S12W21).
IB. Prognos för solaktivitet
Solar activity is expected to be low. There is a small chance for an isolated M-Class flare from Regions 321 (N07W40), 323 (S07W56), 324 (S12W21), or 325 (N10E04).
IIA. Sammanfattning av geofysisk aktivitet 01-2100Z till 02-2100Z
The geomagnetic field was at unsettled to active levels. The high speed stream that began on 30 March has gained slightly in strength to nearly 580 km/sec. Intermittently southward Bz has generated disturbed periods. The greater than 2 MeV electrons at geosynchronous orbit reached high levels.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is expected to be at quiet to minor-storm levels due to the continuing high speed stream, and potential for southward Bz. The high speed stream should diminish tomorrow, and the geomagnetic field should end the day at quiet levels.

VII. Comments: Beginning 1500 UTC April 8, SEC will begin using data from the GOES 12 satellite, and stop receiving GOES 8 data. GOES 12 has the new Solar X-Ray Imager (SXI), which will acquire real-time, operational images of the solar x-ray flux. With the switch from GOES 8 to GOES 12, the primary/secondary designations will change. GOES 12 will be the primary satellite for the SXI. All other data, including magnetometer, XRS x-ray measurements, and energetic particles, will have GOES 10 as their primary source, with GOES 12 as the secondary source where available. Please see http://www.sec.noaa.gov/GOES.html for important information on this changeover.
