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 275 Välja antud 2200Z kuni 02 OCT 1998IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 01-2100Z kuni 02-2100Z SOLAR ACTIVITY WAS VERY LOW. ONLY MINOR B-CLASS
ENHANCEMENTS WERE OBSERVED. REGION 8350 (N20E67) IS A MODERATE SIZE
CLASS E GROUP WITH A BIPOLAR MAGNETIC CONFIGURATION. OTHER REGIONS
WERE STABLE OR DECLINING.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY SHOULD BE PREDOMINANTLY
VERY LOW. REGION 8350 IS CAPABLE OF PRODUCING ISOLATED C-CLASS
EVENTS.
IIA. Summaarne geofüüsikaline aktiivsus 01-2100Z kuni 02-2100Z
THE GEOMAGNETIC FIELD WAS UNSETTLED TO ACTIVE. SOME HIGH LATITUDE
SITES EXPERIENCED PERIODS OF MINOR STORMING. SOLAR WIND DATA SHOW A
HIGH SPEED, LOW DENSITY STREAM IN THE VICINITY OF THE EARTH. A RAPID
INCREASE IN WIND SPEED, TOTAL FIELD, AND TEMPERATURE OCCURRED AROUND
02/0700Z. THE GREATER THAN 10 MEV PROTON EVENT THAT BEGAN ON 30 SEP
CONTINUED TO DECAY DURING THE PERIOD AND FELL BELOW 10 PFU AT
02/0830Z. THE POLAR CAP ABSORPTION EVENT WAS DECLARED OVER AT
02/0300Z. ENERGETIC ELECTRON FLUXES AT GEOSYNCHRONOUS ORBIT REACHED
HIGH LEVELS DURING THE PERIOD.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD SHOULD BE
AT UNSETTLED TO MINOR STORM LEVELS FOR 03-04 OCT. PERIODS OF MAJOR
STORMING ARE POSSIBLE DURING THAT TIME. THIS DISTURBANCE SHOULD
SUBSIDE ON 05 OCT WHEN QUIET TO UNSETTLED LEVELS ARE EXPECTED.
