We have identified twenty-seven candidate very low mass members of the relatively young Alpha Persei open cluster from a six square degree CCD imaging survey. Based on their I magnitudes and the nominal age and distance to the cluster, these objects should have masses less than 0.1 M ⊙ if they are cluster Subject headings: stars: low mass, brown dwarfs; open clusters and associations: individual (Alpha Persei)

Our results have shown that selective processing of RADARSAT-1 images have assisted in regional terrain mapping of large areas the northern boreal forest region in Canada. Terrain roughness information derived from RADARSAT-1 when fused with high resolution DEM data provided image maps that are useful for landform interpretation.

A hyperspectral airborne campaign using the TRWIS sensor was undertaken in August 2001 in Red Lake, Ontario, to study the feasibility of using hyperspectral data as a tool for identifying small mineralized outcrops. In this paper, the methodology and results of correlating airborne and lab spectra are presented for the Marcus site location covered by the survey. Special emphasis is placed on the data post-processing needed for sensor corrections. Our results show that the distribution mapping of some alterations related to gold mineralization on the Marcus site in Red Lake can be made. However not all units were successfully identified from the airborne data.
