Informe actividad solar
Informe de actividad Solar-Geofísica 2023 Jul 28 2200 UTCPreparado por NOAA © SWPC y procesado por SpaceWeatherLive.com
Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 209 Publicado el 2200Z a las 28 Jul 2023IA. Análisis de regiones solares activas y de actividad desde 27-2100Z hasta 28-2100Z Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M4 event observed at
28/1558Z from Region 3376 (N23, L=228). There are currently 10 numbered
sunspot regions on the disk.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (29 Jul, 30 Jul,
31 Jul).
IIA. Resumen de la actividad geofísica 27-2100Z a 28-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 453 km/s at 28/0104Z. Total IMF reached 7
nT at 28/1420Z. The maximum southward component of Bz reached -6 nT at
28/1438Z. Protons greater than 10 MeV at geosynchronous orbit reached a
peak level of 5 pfu at 28/2045Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 753 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to unsettled levels on days one and three (29 Jul, 31
Jul) and quiet to active levels on day two (30 Jul). Protons greater
than 10 Mev are expected to cross threshold on day one (29 Jul) and have
a slight chance of crossing threshold on day two (30 Jul).
