High-resolution observations of the solar photosphere, chromosphere, and transition region

Since the launch of IRIS in June 2013, we have conducted systematic observation campaigns in coordination with the Swedish 1 m Solar Telescope (SST) on La Palma. The SST provides complementary high-resolution observations of the photosphere and chromosphere.

The SST observations include spectropolarimetric imaging in photospheric FeI lines and spectrally resolved imaging in the chromospheric CaII 8542 angstrom, H alpha, and CaII K lines. We present a database of co-aligned IRIS and SST datasets that is open for analysis to the scientific community. The database covers a variety of targets including active regions, sunspots, plages, the quiet Sun, and coronal holes.
