✦ Synopsis

The Mees CCD (MCCD) instrument is an imaging spectroscopy device which uses the 25 cm coronagraph telescope and the 3.0 m Coud6 spectrograph at Mees Solar Observatory (MSO) on Haleakala, Maul The instrument works with resolving power up to R ~ 200000 with significant throughput from 23934 A (Cazt K) to 2 ~ 10000 t~. A fast guiding active mirror stabilizes the image during observations. A rapidly writing magnetic tape storage system allows observations to be recorded at 256 kbytes s-t. Currently, the MCCD is used for imaging spectroscopy of solar flares at 26563 ~ (Ha), and velocity measurements of umbral oscillations; future plans include emission line studies of active region coronae, and photospheric studies of solar oscillations.
