This data set contains calibrated level-2 images and spectra data from the Interface Region Imaging Spectrograph (IRIS). UV images from IRIS telescope record observations of features as small as 240 km (150 miles) on the sun every five to ten seconds at specific temperatures, ranging from 5,000 K to 120,000 K (and up to 10 million K during solar flares). This range allows observations of material moving between the surface of the sun, called the photosphere, and in the lowermost layers of the atmosphere, called the chromosphere and transition region. Spectra are obtained every two to thirty seconds along a slit (1/3 arcsec wide) of solar material at temperatures from 5,000 K to 10 million K, providing information on exactly how much light is visible from any specific wavelength. This corresponds to how much material is present at specific velociites, temperatures and densities. The level-2 data is corrected for dark current, flat-field, and geometric deformation, scaled to the same plate-scale, and packaged into timeseries of slitjaw images and spectral raster scans.
