Abstract:

Under this task, we have augmented the hardware of the Long Wavelength Array LWA to provide a significant riometric capability, in order to search for anomalous absorption events that are associated with radiation belt precipitation events. Although limitations arising from initial data quality and radio frequency interference RFI have slowed implementation, the DTRA-supported augmentations are being incorporated into the standard data flow of the Prototype All-Sky Imager PASI, in order to give real-time, 247 riometry. Incorporation of an outrigger site, to enable treatment of the unknown structure of the celestial background and the effects of confusion noise, was completed. However, RFI issues have prevented combination of outrigger data with LWA1.
