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 196 Välja antud 2200Z kuni 15 Jul 2005IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 14-2100Z kuni 15-2100Z Solar activity was moderate. Region 786 (N09, L=056)
produced an impulsive M1 flare at 14/2257Z. Region 786 continues to
be very active as it rotates around the west limb. It was the source
of a very long duration C2 flare between 15/0943 - 1715Z. An
associated CME was observed off the NW limb on LASCO imagery.
Another flare and CME from this region was in progress at the time
of issue. At 15/2100Z the flare was at the C3 x-ray level, and still
increasing. A 280 sfu Tenflare was also observed with this event.
Region 790 (S10W67) exhibited growth and developed a beta-gamma
magnetic configuration during the period. It produced occasional low
C-class x-ray flares. The rest of the visible disk and limb was
stable.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low.
Region 786 is still producing C-class activity from behind the west
limb. Flare activity from this region will subside over the next
day. Region 790 is expected to produce occasional C-class flares.
Very low activity levels are possible on 18 July as this region
rotates around the west limb.
IIA. Summaarne geofüüsikaline aktiivsus 14-2100Z kuni 15-2100Z
The geomagnetic field was quiet. Solar wind speed declined to near
400 km/s. The greater than 10 MeV proton event that began on
14/0245Z, had a peak flux of 134 pfu at 15/0345Z. The proton flux
gradually decreased to near 60 pfu by the end of the period. The
greater that 2 MeV electron flux at geosynchronous orbit was at high
levels again today.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to range from quiet to minor storm levels. The CMEs
associated with the major flare activity on 13 and 14 July, may
generate active to minor geomagnetic storm periods on 16 and 17
July. The greater than 10 MeV proton event is expected to persist
through 16 July. A new influx of particles from today's CMEs may
prolong the existing proton event.
