Informe de actividad Solar-Geofísica 2021 May 27 2200 UTCPreparado por NOAA © SWPC y procesado por SpaceWeatherLive.com
Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 147 Publicado el 2200Z a las 27 May 2021IA. Análisis de regiones solares activas y de actividad desde 26-2100Z hasta 27-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C3 event observed at
26/2124Z from Region 2826 (N24W60). There are currently 2 numbered
sunspot regions on the disk.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very low
with a chance for a C-class flares and a slight chance for an M-class
flare on days one and two (28 May, 29 May) and expected to be very low
with a slight chance for a C-class flare on day three (30 May).
IIA. Resumen de la actividad geofísica 26-2100Z a 27-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 448 km/s at 27/2035Z. Total IMF reached 16
nT at 27/0254Z. The maximum southward component of Bz reached -11 nT at
27/0518Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 187 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to unsettled levels on day one (28 May) and quiet levels
on days two and three (29 May, 30 May).
