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 105 Välja antud 2200Z kuni 14 APR 2000IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 13-2100Z kuni 14-2100Z SOLAR ACTIVITY REMAINED AT LOW LEVELS. REGION 8948
(S15W63) PRODUCED A LONG-DURATION C1 PARALLEL-RIBBON FLARE AT
13/2130Z ASSOCIATED WITH A SMALL FILAMENT DISAPPEARANCE AND A
PARTIAL-HALO CME. THIS REGION, WHICH REMAINED IN A STATE OF GRADUAL
DECAY, ALSO PRODUCED A C7/1F FLARE AT 14/0816Z. REGIONS 8955
(S22E33) AND 8960 (N19W31) SHOWED MINOR GROWTH DURING THE PERIOD.
THE REMAINING REGIONS WERE STABLE. NO NEW REGIONS WERE ASSIGNED.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE LOW.
THERE IS A FAIR BUT DIMINISHING CHANCE FOR AN ISOLATED LOW-LEVEL
M-CLASS FLARE FROM REGION 8948.
IIA. Summaarne geofüüsikaline aktiivsus 13-2100Z kuni 14-2100Z
GEOMAGNETIC FIELD ACTIVITY WAS AT MOSTLY QUIET LEVELS. THE GREATER
THAN 2 MEV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT WAS AT MODERATE TO
HIGH LEVELS.
IIB. Geofüüsikalise aktiivsuse ennustus
GEOMAGNETIC FIELD ACTIVITY IS
EXPECTED TO INCREASE TO MOSTLY ACTIVE LEVELS ON 16 APRIL IN RESPONSE
TO THE PARTIAL-HALO CME MENTIONED ABOVE. UNSETTLED CONDITIONS ARE
EXPECTED FOR THE REMAINDER OF THE PERIOD. THE GREATER THAN 2 MEV
ELECTRON FLUX IS EXPECTED TO DECREASE TO NORMAL TO MODERATE LEVELS
SOMETIME DURING THE PERIOD.
