abstract = "We have routinely monitored the total frequency (ftEs) and the
blanketing frequency (fbEs) of sporadic E layers with the digital
sounder under the magnetic equator in the Brazilian sector.
Sporadic layers appear in the equatorial region (Esq) at heights
between 90 and 130 km, mainly due to irregularities in the
equatorial electrojet current. However, during the recovery phase
of the October 2003 superstorm, an anomalous intensification of
the ionospheric density that exceeded the normal ambient
background values for local time and location was observed. The
parameter fbEs rose to almost 7.5 MHz during this event, due to a
type c blanketing sporadic layer (Esc), which is driven by wind
shear. This result is discussed in terms of the atmosphere
dynamics based on magnetic signature of the equatorial electrojet
current using magnetometer data. Also, using data measured by
sensors onboard the Geostationary Operational Environmental
Satellite (GOES) 10 we analyze the possible influence of the solar
flare-associated X-ray flux as an additional source of
ionization.",
