abstract = "The ionospheric dynamics in the South America (SA) sector during
geomagnetic disturbed period from 21 to 24 June 2015 is
investigated through ground ionosonde stations and Global
Navigation Satellite System (GNSS) receivers, supported by Very
Low Frequency (VLF) and magnetometer data. These disturbances were
caused by 3 interplanetary shocks (IS) derived from 3 consecutives
coronal mass ejections (CME) from the same solar active region;
the first two CME were caused by filament eruptions, and the third
was a much larger full halo CME, associated with a M2.6 solar
flare. The first 2 shocks were compressive and did not cause an
immediate response to the ionosphere in the analyzed region, while
the third shock increased considerably the electron density from
low to high-latitudes, triggering the second strongest geomagnetic
storm of the 24th solar cycle. It was possible to observe the
expansion of the crest of equatorial ionospheric anomaly (EIA) at
midlatitudes and high-latitudes mainly due to prompt penetration
electric field (PPEF) during the main phase and the recovery phase
of the geomagnetic storm during the day.",
