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 185 Välja antud 2200Z kuni 04 JUL 1998IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 03-2100Z kuni 04-2100Z SOLAR ACTIVITY WAS LOW TO MODERATE. ALMOST ALL OF THE
ACTIVITY WAS PRODUCED BY REGION 8256 (S23W47). THIS REGION HAS
INCREASED IN PLAGE AREA AND SPOT COUNT OVER THE LAST 24 HOURS,
CURRENTLY AN 18 SPOT DRO-BETA. IT HAS PRODUCED SEVERAL C-CLASS
EVENTS AND SUBFLARES AS WELL AS AN M-CLASS EVENT WITH A
CORRESPONDING SN FLARE AT 04/1216UT AND A NEAR M-CLASS EVENT (C9.7)
WITH A 1N FLARE AT 04/1643UT. THE ONLY OTHER REGION SHOWING ANY
ACTIVITY WAS 8260 (S23W14) WHICH PRODUCED AN OPTICAL SUBFLARE AT
04/0739UT. IT HAS SHOWN ONLY MINOR PLAGE FLUCTUATIONS SINCE THAT
TIME. THE REMAINING REGIONS HAVE BEEN QUIET.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO CONTINUE
TO BE LOW TO MODERATE. REGION 8256 IS EXPECTED TO CONTINUE TO
PRODUCE C-CLASS ACTIVITY AND ISOLATED M-CLASS FLARES. REGION 8260
COULD ALSO PRODUCE ISOLATED C-CLASS ACTIVITY.
IIA. Summaarne geofüüsikaline aktiivsus 03-2100Z kuni 04-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED WITH ONE PERIOD OF
ACTIVE CONDITIONS OCCURRING BETWEEN 03/00-03UT. THE GREATER THAN
2MEV ELECTRON FLUX AT GEOSYNCHRONOUS ALTITUDE INCREASED TO NEAR
THRESHOLD LEVELS AT 04/1900UT AND REMAINED THERE FOR THE REST OF THE
REPORTING PERIOD.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FILED IS
EXPECTED TO BE QUIET TO UNSETTLED WITH ISOLATED ACTIVE PERIODS.
