The Equivalent Ionospheric Currents (EICs) data set contains horizontal ionospheric current data (Jx and Jy) derived using the SECS technique [Amm and Viljanen, Earth Planets Space, v. 51 pp. 431-440, 1999]. Positive Jx points to the geographic north pole. Positive Jy points to geographic east. The location of these currents is in geographic coordinates at 10s resolution. The distribution of these currents is not the same as the spherical elementary current amplitudes. The UT and date are obtained from the file name. For more information see Weygand et al. J. Geophys. Res. 116, A03305, doi:10.1029/2010JA016177, 2011.

THEMIS Ground All Sky Imager Keograms for all observatories. Keograms are composed of thin images slices taken down the middle of all-sky images and graphed against time. Keograms allow for substorm analysis without the need for full sized raw images. The ASI stations each monitor a 170 degree field of view imaging the auroral oval at kilometer resolution. The ASI is comprised of a fisheye lens and CCD 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 a sun shades deploy to protect the CCD.

THEMIS Ground All Sky Imager at The Pas: 32 x 32 pixel thumbnails for full ASI images. 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 in a stainless steel enclosure topped with a transparent acrylic dome. The CCD has a resolution of 256 x 256 pixels. 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.
