WE PROPOSE TO CONTINUE A LONG-TERM OBSERVATIONAL CAMPAIGN TO CHARACTERIZE MAIN-BELT COMETS (MBCS) WHICH WE HAVE BEEN MONITORING REGULARLY SINCE THEIR DISCOVERIES AND CONDUCT A NEW INVESTIGATION OF A GROUP OF POSSIBLY RELATED OBJECTS. FOR THE FIRST PORTION OF OUR PROJECT WE WILL MONITOR AND ANALYZE THE ACTIVE PHASES OF THE MBCS THAT EXHIBIT ACTIVITY DURING THE PROJECT PERIOD CHARACTERIZE THE EVOLUTION OF THAT ACTIVITY AND CHARACTERIZE MBC NUCLEUS PROPERTIES. FOR THE SECOND PORTION OF OUR PROJECT WE WILL OBSERVATIONALLY CHARACTERIZE THE NUCLEI AND ACTIVITY OF APPARENT JUPITER-FAMILY COMETS (JFCS) THAT HAVE BEEN IDENTIFIED AS POTENTIALLY ORIGINATING IN THE ASTEROID BELT (LEADING US TO REFER TO THEM AS POSSIBLE NEAR-EARTH MBCS OR NEMBCS) AND DETERMINE WHETHER PHYSICAL EVIDENCE SUPPORTS THEIR PROPOSED MAIN-BELT ORIGINS.
