Alert Notice 321: Multicolor CCD campaign for AS 325 to support Spitzer observations

July 13, 2005

We request nightly BVRI CCD observations of the symbiotic eclipsing binary star AS 325 until December 1, 2005. The goal of the campaign is to determine the nature of this enigmatic system by looking for changes in color during the current eclipse and also to support upcoming observations with the Spitzer Space Telescope planned for September.
