Detecting Brown Dwarfs in Interacting Cataclysmic Binaries Proposal News News: The Brown Dwarf group presented two posters at the January AAS - one on their scientific results and the other on their educational efforts. The Brown Dwarf team has published an ApJ article which can now be viewed online entitled "First Spitzer Space Telescope Observations of Magnetic Cataclysmic Variables: Evidence of Excess Emission at 3-8 microns". - a pdf file Status: All of the group's objects have been observed and are in the archives. GG Leo and AAVSO 0150-60 (J0153.9-5948) have been reduced and are being analyzed. V347 Pav was released on September 2 and has not yet been reduced.
