Solaktivitetsrapport
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.

USAF/NOAA rapport för sol- och geofysisk aktivitet
SDF Nummer 159 publicerat klockan 2200Z på 07 Jun 2004IA. Analys av solfläcksgrupper och solaktivitet från 06-2100Z till 07-2100Z Solar activity increased to low levels today. Region
621 (S14W57) produced the largest flare of the period, a long
duration C2 x-ray event that occurred at 07/0045Z. A faint,
asymmetrical full halo CME resulted from the event which appears to
have a weak Earthward directed component. This region has undergone
further decay today in sunspot coverage. Region 627 (S08E04) grew
in sunspot area and magnetic complexity. Region 624 (S08W18)
produced a low level B-class flare at 06/2253Z. Regions 628
(S09E13), 629 (S04E22), and 630 (N13E56) were numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be at
very low to low levels.
IIA. Sammanfattning av geofysisk aktivitet 06-2100Z till 07-2100Z
The geomagnetic field was at quiet to unsettled levels. The greater
than 2 MeV electron flux at geosynchronous orbit reached high levels
again today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at quiet to active levels throughout the period.
Weak recurrent coronal hole influences and associated elevated wind
speeds are anticipated on 8 and 9 June, especially at higher
latitudes. A glancing blow from the faint full halo CME that
resulted from the long duration C2 flare is expected to transit the
Earth's geomagnetic field on 10 June.
