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.

IA. Análisis de regiones solares activas y de actividad desde 18-2100Z hasta 19-2100Z
Solar activity decreased to very low levels. Flare
activity was limited to several B-class flares. Region 386 (S07E30)
lost penumbral coverage over the period although it does retain a
delta magnetic structure in the dominant lead spot. Region 387
(N18E49) grew in both penumbral coverage and magnetic complexity
since yesterday, a gamma structure is now evident in the trailing
portion of the spot group. Newly numbered Region 388 (S03E08)
produced a minor B-class flare early in the period.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
moderate levels. Region 386 remains capable of producing an
isolated major flare.
IIA. Resumen de la actividad geofísica 18-2100Z a 19-2100Z
The geomagnetic field was at predominantly active levels today.
Minor storm conditions were observed at both middle and high
latitudes between 19/0000 and 0300Z due to the influence of a
recurrent high speed coronal hole stream. The greater than 10 MeV
proton flux exceeded event threshold at 18/2050Z (reached a max of
24 pfu at 19/0450Z), ended at 19/1900Z and after careful review the
event is believed to have been the result of the M6.8 x-ray flare
from June 17. The greater than 2 MeV electron flux reached moderate
levels today.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at predominantly unsettled to active levels through
the interval. Minor storm conditions may exist due to a transient
passage during the first half of day one in response to the M6.8
x-ray flare from June 17.

GOES Protons:
To ensure continued operational monitoring of important energetic particle data, it is necessary to reassign primary/secondary designations for the GOES Space Environment Monitor (SEM) detectors. GOES 11 (113W) is now the primary satellite for protons. GOES 12 will continue as the primary satellite for magnetometer, X-ray, and electron measurements. GOES 10 (135W) will be the secondary satellite for all SEM sensors - magnetometer, X-ray, and energetic particles. Because of the degraded state of the proton data on GOES-10, its designation as the secondary source for proton data is a short-term solution. More permanent solutions have been identified and are being evaluated. Users will be notified when we define and schedule a permanent fix. Further details can be found at http://www.sec.noaa.gov/GOES.html.
K-Indices:
On 16 June, it was determined that a scaling problem exists with the Boulder magnetometer instrument. While this problem, and its fix are being investigated the primary instrument for Boulder K-indices has been switched to the Boulder USGS (via Domsat) magnetometer, effective 1500 UTC on 16 June.
