Quasi‐monochromatic waves with an electrostatic nature in the lower hybrid frequency range have been identified in the plasma sheet boundary layer at X GSM =−49R e and −69R e by the wave‐form observations in a band 0–25 Hz from the double probe onboard the GEOTAIL spacecraft. Simultaneous measurements of low energy ions also indicate that the wave coincides with the transition of the ion‐energy from 0.1 keV/e to 10 keV/e.
