Resumen:
In the interval of 4-10 September 2017, the Sun presented multiple solar
flares from active region AR 2673. There were also coronal mass
ejections that interacted with the Earth's magnetosphere. This solar
activity produced several space weather events. These events were
observed with ground-based instruments of the Mexican Space Weather
Service. The Mexican Array RadioTelescope detected highly perturbed
solar transits associated with Type I radio emissions from active
regions. The Compact Astronomical Low-frequency, Low-cost Instrument for
Spectroscopy in Transportable Observatories-Mexican Array RadioTelescope
station detected several radio bursts including a Type III associated
with the X8.2 flare on 10 September. The magnetometer detected
variations reaching a regional K index of 8.3 during the geomagnetic
storm. The ionosphere over Mexico was disturbed by different space
weather phenomena with the dominant effects of the geomagnetic storm. We
used total electron content data to study latitudinal and longitudinal
ionospheric effects in this interval. The cosmic rays monitor detected a
Forbush decrease associated also with the geomagnetic storm. This
low-latitude instrumental network in Mexico allowed estimating the
regional response to space weather events. Coincidentally with the space
weather events referred above, there were also two other types of
natural hazards affecting the country at that moment, the hurricane
Katia category 2 in the Gulf of Mexico, and two major earthquakes (7 and
19 September 2018). The conjunction of these natural phenomena were
close to creating a worst-case scenario in terms of civil protection
reaction.
