Range-time-intensity plot of the FAI in the F region observed on the beam with azimuth of 234.2°, 207.0°, 180.0°, 153.0°, and 125.8° (from top to bottom panels) with the 30.8 MHz radar at Kototabang, Indonesia on the nights of (left) August 21, 2007, and (right) July 8, 2007. Left vertical axis shows the range from the radar and the right axis shows the altitude at which the radar beam is perpendicular to the geomagnetic field. (after Otsuka et al. 2009)
