Informe actividad solar
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.

Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 136 Publicado el 2200Z a las 16 May 2005IA. Análisis de regiones solares activas y de actividad desde 15-2100Z hasta 16-2100Z Solar activity was moderate. Region 763 (S16E04)
produced three low level M-class flares. The largest of these
flares was a M3.5 at 15/2236 UTC. This region has increased in size
and complexity and now exhibits a beta-gamma magnetic
classification. Beginning at 16/1350 UTC, LASCO imagery showed what
appeared to be a partial halo CME. This event was actually two
events. The first was a DSF near Region 759 (N11W35) at
approximately 16/1243 UTC and the second was a backside event at
approximately 16/1358 UTC. Most of the front side ejection was
directed northward; therefore, the event is not likely to be
geoeffective.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
to moderate.
IIA. Resumen de la actividad geofísica 15-2100Z a 16-2100Z
The geomagnetic field was at quiet to minor storm levels with a
period of major storm conditions between 16/0300 UTC and 0600 UTC.
Solar wind speed at ACE has been steadily decreasing from
approximately 800 km/s to 550 km/s by the end of the period. The Bz
component of the IMF has remained south between -1 nT and -10 nT
during this reporting period. The greater than 2 MeV electron flux
at geosynchronous orbit was high today.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be unsettled to active with an isolated minor storm
period possible on 17 May due to a recurrent coronal hole high speed
stream becoming geoeffective. Quiet to unsettled conditions are
expected on 18 and 19 May.
