The ASI stations monitor a 170 degree field of view imaging the auroral oval at kilometer resolution. The ASI is comprised of a fisheye lens and CCD (resolution 256 x 256 pixels) in a stainless steel enclosure topped with a transparent acrylic dome. Exposure control ranges from 5 s to 1 ms although the typical data rate is one image every 3 seconds. Silicone heaters keep the instrument within the nominal temperature range. During daylight hours sun shades deploy to protect the CCD. We acknowledge NASA contract NAS5-02099 and V. Angelopoulos for use of data from the THEMIS Mission; specifically S. Mende and E. Donovan for use of the ASI data. spase://SMWG/Person/Vassilis.Angelopoulos PrincipalInvestigator spase://SMWG/Person/Stephen.B.Mende CoInvestigator spase://SMWG/Person/Eric.Donovan CoInvestigator THEMIS All Sky Imager Instrument http://themis.ssl.berkeley.edu/instrument_asi.shtml Brief description of ASI instrument and links to related papers.
