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 352 Publicado el 2200Z a las 18 Dec 2015IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C4 event observed at
18/0509Z from Region 2469 (N19W15). There are currently 3 numbered
sunspot regions on the disk.
IB. Pronóstico de la actividad solar
Solar activity is likely to be low with a
slight chance for an M-class flare on days one, two, and three (19 Dec,
20 Dec, 21 Dec).
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 508 km/s at
17/2112Z. Total IMF reached 6 nT at 17/2232Z. The maximum southward
component of Bz reached -5 nT at 17/2113Z. Electrons greater than 2 MeV
at geosynchronous orbit reached a peak level of 933 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at active to major storm levels on day one (19 Dec), quiet to
active levels on day two (20 Dec) and quiet to unsettled levels on day
three (21 Dec).
