AB: We will describe a new instrument that is being built to measure the velocity, intensity and line-of-sight magnetic fields of the full solar disk, simultaneously at four heights in the solar atmosphere with a resolution of 4 arc-seconds and a cadence of 10 seconds. The heart of the instrument is the magneto-optical filter [1] that can be operated using vapor cells containing K, Na, Ca and He. The instrument is also designed to have a high-resolution imaging mode that will provide 1 arc-second resolution over a FOV of 450x450 square arc-seconds. The instrument is scheduled for deployment to South Pole during the Austral summer of 2005/2006. This work is funded by award OPP-0338251 from the National Science Foundation.
