The new HF heating facility with the ISR (Incoherent Scatter Radar) and other instruments provides a unique opportunity to study heating related aeronomic and plasma physics problems. This includes very sensitive rapidly-imaged, high horizontal- and time-resolution imaging of airglow at 557.7 nm, 630.0 nm and 427.8 nm during ionospheric "heating" to understand the role of HF-heating in generating plasma bubbles, or modulating them if already present, and to understand the role of secondary suprathermal electrons in producing airglow at different wavelengths, if any. This research will also yield insight to the heating processes including locating ionospheric "hot-spots", yielding details of the electron collision process, elucidating the role of Langmuir and ion-acoustic waves in the strongly heated regions, and study of heating effects in Sporadic E. The latter study will include Ca+ metal-lidar observations as further defined by 555.7 nm imaging as well as ISR and HF radar results.
