We present the first quasiperiodic (QP) echoes from 3-m E region field-aligned irregularities observed in the Southamerican sector, just outside the magnetic equator (7.5°N geomagnetic). These QP echoes occur only at night and between 105 and 120 km. In general, Piura QP echoes present periods close to the Brunt-Vaisala period (5 to 10 min), striations with positive slopes and altitude rates of 20-25 m s−1 (upward/northward), striations spacings of 3 to 10 km, and downward/southward Doppler… CONTINUE READING
