Päikese aktiivsuse aruanne

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.

Ühine USAF / NOAA päikese- ja geofüüsikaalase aktiivsuse aruanne

SDF number 096 Välja antud 2200Z kuni 06 Apr 2003

IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 05-2100Z kuni 06-2100Z

Solar activity was at low levels. Region 324 (S12W74) produced two C-class flare with the largest a C5 flare at 06/1928Z. Region 324 continues to show gradual decay and has simplified to a beta-gamma magnetic configuration. The two largest regions on the disk, Region 325 (N13W48) and Region 330 (N07E38), have both increased in spot count and have developed beta magnetic configurations. Area coverage has been relatively unchanged.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be at low levels. Regions 324, 325, 330 have C-class potential and may produce an isolated M-class event.
IIA. Summaarne geofüüsikaline aktiivsus 05-2100Z kuni 06-2100Z
The geomagnetic field was at quiet to unsettled conditions. High speed stream effects have diminished with solar wind velocity decreasing to near 450 km/s and Bz oscillations subsiding.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is expected to be at quiet to isolated active levels. There is a slight chance of a weak CME shock late on day two or early on day three, which could produce isolated active conditions.

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.
