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 094 Välja antud 2200Z kuni 04 Apr 2003

IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 03-2100Z kuni 04-2100Z

Solar activity was low to moderate. Along with several C-class flare events, Region 324 (S08W40) produced a significant long-duration M1.9 flare at 2019 UTC. Several regions including 324, 321 (N08W68), and 323 (S07W87) continue to show considerable low-level activity.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be moderate for the next two days, dropping off to low when Region 324 (S11W40) makes its way off the visible disk.
IIA. Summaarne geofüüsikaline aktiivsus 03-2100Z kuni 04-2100Z
The geomagnetic field has been at low to active levels with periods of minor storming due to the continued influence of a high-speed solar wind stream. The greater than 2 MeV electrons at geosynchronous orbit reached high levels.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is expected to be at quiet to unsettled levels with isolated periods of active conditions during the next 24 hours. The waning high-speed stream will decrease the geomagnetic field to quiet levels with isolated periods of unsettled on the second and third days.

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.
