Description
Chromospheric Helium-I Imaging Photometer: a differential imager using the He I 1083 nm line (with nearby calibration wavelengths) via a tunable liquid-crystal Lyot filter and IR CCD, producing images every 3 minutes for CME, coronal-hole and prominence studies; installed at MLSO in April 1996.
