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 318 Välja antud 2200Z kuni 14 NOV 1998IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 13-2100Z kuni 14-2100Z SOLAR ACTIVITY WAS LOW. REGION 8385 (N21W69) PRODUCED
SEVERAL C-CLASS X-RAY EVENTS DURING THE PERIOD WITH THE LARGEST A
C5/SF AT 13/2059Z. REGION 8383 (S15E02) PRODUCED A C1/SF AT
14/1441Z. AN OPTICALLY UNCORRELATED C1 X-RAY FLARE OCCURRED AT
14/0210Z. ANOTHER OPTICALLY UNCORRELATED C1 X-RAY FLARE OCCURRED AT
14/0508Z AND WAS ASSOCIATED WITH A TYPE IV RADIO SWEEP. THE PROBABLE
SOURCE FOR THIS EVENT WAS OBSERVED BY SOHO/LASCO FROM BEHIND THE
DISK IN THE NORTHWEST. THIS WAS LIKELY FROM REGION 8375 WHICH MADE
ITS TRANSIT BEHIND THE DISK A COUPLE DAYS AGO. TWO NEW REGIONS WERE
NUMBERED TODAY AS REGION 8387 (N22E46) AND REGION 8388 (N23E55).
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE LEVELS. REGIONS 8383 AND 8385 ARE CAPABLE OF PRODUCING C
AND M-CLASS FLARES.
IIA. Summaarne geofüüsikaline aktiivsus 13-2100Z kuni 14-2100Z
THE GEOMAGNETIC FIELD WAS AT ACTIVE TO MINOR STORM LEVELS. THE GT 10
MEV AND GT 100 MEV PROTONS REACHED EVENT LEVEL TODAY. THE GT 10 MEV
STARTED AT 14/0810Z WITH A MAXIMUM OF 300 PFU AT 14/1245Z. THE GT
100 MEV STARTED AT 14/0755Z WITH A MAXIMUM 6.1 PFU AT 14/0950Z. BOTH
EVENTS REMAIN IN PROGRESS.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED THROUGH THE FORECAST PERIOD. THE
PROBABLE CAUSE OF TODAYS ACTIVITY WAS THE PARTIAL HALO CORONAL MASS
EJECTION ON 09 NOV. THE GT 10 MEV AND GT 100 MEV EVENTS ARE EXPECTED
TO RETURN TO BACKGROUND LEVEL BY THE FIRST DAY OF THE FORECAST.
