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.

SDF number 135 Välja antud 2200Z kuni 15 May 2003
IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 14-2100Z kuni 15-2100Z
Solar activity has been low. Two new regions were
numbered today: Region 361 (N09E39) and Region 362 (S10E77).
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be very
low, with possible increase in activity over the next few days due
to active regions emerging from the east limb. New region 362 may
produce isolated flare activity.
IIA. Summaarne geofüüsikaline aktiivsus 14-2100Z kuni 15-2100Z
The geomagnetic field has been at unsettled to minor storm levels due
to a high speed solar wind stream from a favorably positioned
coronal hole. The greater than 2 MeV electron flux at
geosynchronous orbit reached high levels today.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be at unsettled to active levels for the next three
days. Solar wind speeds should continue to reduce over the next few
days, and may cause isolated minor storm levels on day one.

VII. Comments
The GOES 10 energetic proton detectors are showing intermittent, high noise levels in the higher energy proton channels (greater than about 80 MeV). This problem was first noticed in data taken April 26, 2003. To ensure continued operational monitoring of important energetic particle data, it is necessary to reassign primary/secondary designations for the GOES Space Environment Monitor (SEM) detectors. As of 1500 UT on May 15, GOES-8 became the primary satellite for protons. GOES 12 will be the primary satellite for magnetometer, X-ray, and electron measurements. GOES 10 will be the secondary satellite for all SEM sensors - magnetometer, X-ray sensor, and energetic particle sensor. This short-term solution (approximately 2 - 3 months) will be in place until we define and implement a permanent fix. A more detailed explanation can be found at: http://www.sec.noaa.gov/GOES.html.
