• NORSTAR - 
• NORSTAR is an optical and radio facility designed to remote sense auroral precipitation on a continental scale. NORSTAR provides data of stand-alone scientific value and complements other ground-based and in situ observations. NORSTAR's heritage is CANOPUS, and it will be the imaging component of CGSM. NORSTAR consists of three CCD-based All-Sky Imagers (ASIs), four Meridian Scanning Photometers (MSPs), and 13 riometers. There are plans for seven more ASIs. The ASIs and MSPs collect data at four auroral wavelengths (471, 558, 630, 486 nm), at a cadence of 10-60 s/image. The RIOMETERs operate at 28 MHz and 0.2 Hz.
