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 119 Välja antud 2200Z kuni 29 Apr 2001IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 28-2100Z kuni 29-2100Z Solar activity remained low. Region 9433 (N18W63)
produced isolated C-class subflares as it continued to show gradual
decay in its lead and intermediate spots. However, no significant
changes occurred within its trailer spots, where a magnetic delta
configuration persisted. Region 9441 (N07E11) continued a gradual
growth phase, but remained simply structured. Region 9444 (S11E52)
showed minor spot and penumbral development. Region 9445 (N24E61)
also exhibited minor spot and penumbral development and produced
isolated C-class subflares late in the period. New Region 9446
(S05W22) was numbered.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be at
moderate to high levels. Region 9433 is expected to produce isolated
low-level M-class flares during the period. It may also produce an
isolated major flare before crossing the west limb on 02 May.
IIA. Summaarne geofüüsikaline aktiivsus 28-2100Z kuni 29-2100Z
Geomagnetic field activity ranged from quiet to active levels. The
geomagnetic field disturbance that began yesterday subsided to quiet
to unsettled levels after 29/0600 UTC.
IIB. Geofüüsikalise aktiivsuse ennustus
Geomagnetic field activity is
expected to be at quiet to unsettled levels during the period.
Region 9433 could produce a proton flare before crossing the west
limb on 02 May.
