Päikese aktiivsuse aruanne
Igale käesolevas aruandes mainitud päikesepurskele on kohaldatud Kosmose Ilmaennustuskeskuse (SWPC) skaalafaktor. SWPC skaleerimisteguri tõttu on päikesepursked esitatud 42% väiksemana kui samade teadusliku kvaliteediga andmete puhul. Meie arhiveeritud päikesepursete andmetest on skaleerimisstegur eemaldatud, et kajastada tegelikke füüsikalisi ühikuid.

Ühine USAF / NOAA päikese- ja geofüüsikaalase aktiivsuse aruanne
SDF number 211 Välja antud 2200Z kuni 30 Jul 2005IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 29-2100Z kuni 30-2100Z Solar activity was high. Region 792 (N12E52) produced
an X1/2b event today with maximum at 0635 UTC. The event had a long
decay time and was associated with Type II and Type IV radio sweeps.
The event was also associated with a fast, full halo CME. The CME
had an estimated plane-of-sky speed in the range of 1700-1800 km/s
in the LASCO C3 field of view, and was somewhat asymmetric towards
the east. Region 792 consists of a compact cluster of spots and
appears to have at least two delta configurations within its complex
magnetic configuration. In addition to the X-flare, Region 792 also
produced a C9/1n at 0519 UTC and a C8/Sf at 1707 UTC. Another CME
has been observed following the C8 event, but so far appears to be a
limb event rather than a partial or full halo event.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be
mostly moderate for the next three days (31 July - 02 August), but
there is a fair chance for additional, isolated major flare activity
from Region 792. In addition, there is an increasing likelihood that
major flare activity from Region 792 will lead to enhanced proton
flux as the group rotates closer to disk center.
IIA. Summaarne geofüüsikaline aktiivsus 29-2100Z kuni 30-2100Z
The geomagnetic field ranged from quiet to active levels during the
past 24 hours. Solar wind data show a gradual decline in velocity,
indicating the transition from a high speed stream to normal solar
wind conditions; day end velocities were at 470-480 km/s. The
greater than 10 MeV proton event that began at 27/2300 UTC continues
in progress. The maximum flux observed so far is 41 PFU at 29/1715
UTC. There was no detectable upturn in proton flux from today's
major flare/CME event, although it may be contributing to the
prolonging of the currently enhanced flux levels. The greater than 2
MeV electron flux at geosynchronous orbit reached high levels during
the past 24 hours.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be generally unsettled for 31 July. A glancing blow from
today's full halo CME is expected early on 01 August and is expected
to increase activity to predominantly active levels, with a chance
for some minor storm periods. Conditions should decline to unsettled
to slightly active by 02 August.
