Abstract
Context. The wings of the Ca ii H and K lines provide excellent photospheric temperature diagnostics. At the Swedish 1-m Solar Telescope (SST), the blue wing of Ca ii H is scanned with a narrowband interference filter mounted on a rotation stage. This provides up to 010 spatial resolution filtergrams at high cadence that are concurrent with other diagnostics at longer wavelengths.
