Solaktivitetsrapport
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.

USAF/NOAA rapport för sol- och geofysisk aktivitet
SDF Nummer 155 publicerat klockan 2200Z på 04 JUN 1999IA. Analys av solfläcksgrupper och solaktivitet från 03-2100Z till 04-2100Z SOLAR ACTIVITY WAS MODERATE. REGION 8552 (N19W86)
PRODUCED AN M3/2B FLARE AT 04/0703UT. THIS FLARE WAS ASSOCIATED WITH
AN INTENSITY 3 TYPE IV SWEEP AND A PARTIAL HALO CME. NUMEROUS
C-CLASS FLARES ALSO OCCURRED DURING THE PAST DAY FROM A NUMBER OF
REGIONS. NEW REGIONS NUMBERED INCLUDE 8568 (N12W55), 8569 (N18E73),
AND 8570 (S14E74).
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. C-CLASS FLARES ARE EXPECTED AND ADDITIONAL M-CLASS
FLARES ARE POSSIBLE.
IIA. Sammanfattning av geofysisk aktivitet 03-2100Z till 04-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. A GREATER THAN 10 MEV
PROTON EVENT BEGAN AT 04/0925UT AND REMAINS IN PROGRESS. SO FAR THE
MAXIMUM FLUX OF THIS EVENT WAS 64 PFU AT 04/1055UT. THE EVENT SOURCE
IS PRESUMED TO BE THE M3/2B AND CME AT 04/0703UT. A PCA EVENT WAS
ASSOCIATED WITH THE PARTICLES, BEGINNING AT 04/1040UT AND REACHING A
MAXIMUM ABSORPTION OF 2.5 DB AT 04/1850UT.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED BECOMING UNSETTLED TO ACTIVE IN
RESPONSE TO THE CME EVENT DESCRIBED ABOVE.
