Abstract: A Travelling Ionospheric Disturbance (TID) passing over Adelaide, Australia was observed simultaneously in 630.0 nm airglow images and high time resolution 2 – 22 MHz ionospheric sounder data by the Defence Science and Technology Group (DST group) on the 27th of January 2014 from approximately 10 UT to 20 UT. A comparison between the two observations shows a strong inverse correlation between the night-time ionospheric virtual height measurement, h'F, and airglow intensity in both large and small scale features. This event was unusual in two ways: a) it occurred at solar maximum and b) part of the TID split into a smaller TID before reforming. TID wavelength, velocity and period parameters calculated from both airglow and high-frequency (HF) radio measurements and are found to be in agreement.
