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 216 Välja antud 2200Z kuni 04 AUG 1999IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 03-2100Z kuni 04-2100Z SOLAR ACTIVITY REMAINED AT HIGH LEVELS. REGION 8647
(S18W75) PRODUCED AN M6/1N FLARE AT 04/0557Z ASSOCIATED WITH A WEAK
TYPE II RADIO SWEEP (EST. SHOCK VELOCITY 400 KM/SEC) AND A 230 SFU
TENFLARE. IT ALSO PRODUCED AN M1/SF FLARE AT 04/1607Z. THIS REGION
SHOWED LITTLE CHANGE DURING THE PERIOD AND WAS OF MODERATE SIZE AND
MAGNETIC COMPLEXITY. REGION 8651 (N25W31) REMAINED A LARGE F-TYPE
GROUP OF MODERATE MAGNETIC COMPLEXITY, BUT APPEARED TO BE SLOWLY
DECAYING. IT PRODUCED TWO SUBFLARES DURING THE PERIOD. REGION 8645
(S26W66) REMAINED MODERATE IN SIZE AND MAGNETIC COMPLEXITY AND
SHOWED LITTLE CHANGE AS IT PRODUCED ISOLATED SUBFLARES. NEW REGION
8660 (S34W25), A SMALL B-TYPE GROUP, WAS NUMBERED TODAY.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE
MODERATE. ISOLATED M-CLASS FLARES ARE POSSIBLE FROM REGIONS 8645,
8647, AND 8651. THERE IS ALSO A CHANCE FOR ANOTHER MAJOR FLARE FROM
REGION 8647.
IIA. Summaarne geofüüsikaline aktiivsus 03-2100Z kuni 04-2100Z
THE GEOMAGNETIC FIELD WAS AT QUIET TO ACTIVE LEVELS. A SUDDEN IMPULSE
OCCURRED AT 04/0225Z (25 NT, AS MEASURED BY THE BOULDER USGS
MAGNETOMETER). FIELD ACTIVITY INCREASED FOLLOWING THE IMPULSE WITH
ACTIVE LEVELS DETECTED DURING THE 04/0300 - 0600Z INTERVAL. ACTIVITY
DECREASED TO QUIET TO UNSETTLED LEVELS DURING THE REMAINDER OF THE
PERIOD.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE AT QUIET TO UNSETTLED LEVELS THROUGH THE PERIOD.
THERE APPEARED TO BE NO EARTH-DIRECTED CORONAL MASS EJECTIONS
ASSOCIATED WITH THE MAJOR FLARES OF 02 AND 04 AUGUST.
