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 168 Publicado el 2200Z a las 17 Jun 2011IA. Análisis de regiones solares activas y de actividad desde 16-2100Z hasta 17-2100Z Solar activity decreased to very low levels. Region
1234 (S16W48) and Region 1236 (N17E33) each produced isolated
B-class x-ray flares. A B7 x-ray flare occurred near the SE limb at
17/0646Z. Region 1234 showed a gradual increase in interior spots
during the period and was classified as a Dsi group with a simple
bipolar magnetic structure. Region 1236 showed a gradual decrease in
magnetic complexity in its trailer portion and was classified as a
Dho with a beta-gamma magnetic structure. No new regions were
numbered. No Earth-directed coronal mass ejections (CME) were
observed during the period.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
through the period (18 - 20 June) with a chance for an isolated
M-class flare.
IIA. Resumen de la actividad geofísica 16-2100Z a 17-2100Z
Geomagnetic activity was at quiet to active levels. An active period
was observed during 07/0000 - 0300Z. A geomagnetic sudden impulse
(SI) was observed at Boulder at 17/0244Z (31 nT) and indicated the
arrival of the partial-halo CME observed on 14 June.
IIB. Pronóstico de la actividad geofísica
Geomagnetic activity is
expected to be at quiet to unsettled levels on day 1 (18 June).
Activity is expected to decrease to quiet levels on day 2 (19 June).
An increase to quiet to unsettled levels is expected on day 3 (20
June) as a coronal hole high-speed stream begins to disturb the
field.
