We show that the vertical polarization electric field (E-p) in the topside of the equatorial electrojet can be determined from the Doppler spectra of type-2 echoes obtained with a radar that is appropriately displaced in latitude from the magnetic dip equator. Using a 49.92 MHz radar on Christmas Island (2.9 degrees magnetic dip latitude), we found unexpectedly large E-p at altitudes at least as high as 120 km over the dip equator. Another new and related finding is the transient appearance of type-1 echoes at 99 km over Christmas Island, which likely was produced by an E-p of at least 11 mV/m that must have appeared at 114 km altitude over the dip equator. Elevated electron temperatures inferred from the type-1 Doppler spectra are consistent with the presence of anomalous energetics. [References: 13]
