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 141 Publicado el 2200Z a las 20 May 2008

IA. Análisis de regiones solares activas y de actividad desde 19-2100Z hasta 20-2100Z

Solar activity was very low. No flares occurred during the past 24 hours. The two spotted regions on the disk were quiet and stable,
IB. Pronóstico de la actividad solar
Solar activity is expected to be very low.
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z
The geomagnetic field was quiet to unsettled. A small increase in solar wind speed from around 360 km/s up to about 440 km/s occurred between 1200-1400Z. The solar wind signatures are consistent with a high speed stream from a coronal hole.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected to be unsettled to active with a chance for isolated minor storm periods for the first day (21 May) as the high speed stream is expected to continue. Observations of the solar wind at the Stereo-B spacecraft suggest that the solar wind velocity should increase to around 550-600 km/s. Activity levels are expected to decline to unsettled levels with occasional active periods for the second day (22 May) and should be predominantly unsettled for the third day (23 May).
