abstract = "This paper presents a medium-scale traveling ionospheric
disturbance (MSTID) occurrence detected through the OI 630.0 nm
emission all-sky images, obtained by ground-based imaging systems
installed at close geomagnetic conjugate locations: one at the
Southern Space Observatory-SSO/CRS/INPE-MCTI, (29.4°S, 53.8°W), in
Sao Martinho da Serra, RS, Brazil, and another at the Arecibo
Observatory (18.3°N, 66.7°W), in Puerto Rico. The images obtained
show the optical signature of MSTIDs (low intensity regions of
630.0 nm airglow emission), propagating simultaneously in both
hemispheres, during geomagnetically quiet conditions (Kp<3).
Observations using digital ionosonde installed at Falkland Islands
(51.4°S, 57.5°W) and Ramey, Puerto Rico (18.5°N, 67.1°W) show an
abrupt upward motion of the ionospheric F region plasma and the
occurrence of frequency-type spread-F that could be related to the
MSTIDs observed optically. Using Global Positioning System (GPS)
receiver data, we also obtained the rate of the Total Electronic
Content (TEC) change (ROT) for two geomagnetically conjugated
sites-Santa Maria (29.7°S, 53.7°W) and Virgin Islands (17.7° N,
64.7°W). The analysis of TEC allows us to identify an irregular
ionization in the F layer associated with the passage of an MSTID.
The possible effects of the South America Magnetic Anomaly (SAMA)
on the electrodynamic processes that control the inter-hemispheric
coupling that give origin to the conjugate MSTIDs are highlighted
and discussed.",
