GOALS AND OBJECTIVESBEGINNING FEBRUARY 2006 THE ASTRONOMICAL RESEARCH INSTITUTE ARI MADE ITS FIRST NEO OBSERVATION AND IN A SINGLE DECADE HAS PRODUCED MORE THAN 129 488 MEASURES EXCEEDING ALL OTHER RESEARCH FACILITIES WORLDWIDE. OUR GOAL IN CONTINUING THIS RESEARCH IS TO PROVIDE A DEDICATED COST EFFECTIVE NEO FOLLOW UP PROGRAM THAT WILL ALLOW NASA TO COMPLETE THEIR GOAL OF CATALOGING POTENTIALLY HAZARDOUS NEAR EARTH OBJECTS TO 100 METERS.ARI HAS BEEN AN INTEGRAL PART OF NASAS NEOO PROGRAM FOR THE PAST NINE YEARS. UTILIZING FOUR TELESCOPES LOCATED AT THE INSTITUTE OUR PRIMARY OBJECTIVE IS TO PROVIDE THE LONGEST POSSIBLE ORBITAL ELEMENTS SPECIFICALLY FOR OBJECTS FAINTER THAN MAGNITUDE 22.0. THE PRINCIPAL GOAL OF THIS FACILITY IN PHASE IV WILL BE TO MEASURE MORE THAN 2 000 NEAS THAT ARE FAINTER THAN 22ND MAGNITUDE IN ORDER TO MAKE THEIR FUTURE RECOVERY MUCH MORE PROBABLE DURING THE OBJECTS NEXT OPPOSITION.APPROACH AND METHODOLOGYARI WILL CONTINUE TO FOCUS ON NEO CONFIRMATION PAGE OBJECTS AS A MAJOR PRIORITY. OUR SECONDARY GOAL IN THIS RESEARCH WILL BE TO CONDUCT FOLLOW UP OBSERVATIONS OF FIRST OPPOSITION NEOS AND THOSE REQUIRING ADDITIONAL OBSERVATIONS AS SPECIFIED BY THE MINOR PLANET CENTER MPC. ARIS LOWEST PRIORITY IN PHASE IV WILL BE TARGETED FOLLOW UP OF MULTIOPPOSITION OBJECTS.AS THE LARGE SKY SURVEYS SUCH AS PANSTARRS AND THE MT. LEMMON SURVEY CONTINUE TO MAKE NEW DISCOVERIES OF OBJECTS FAINTER THAN 22ND MAGNITUDE THE NEED FOR FAINT FOLLOW UP BECOMES MORE IMPERATIVE. DURING PHASE IV ARI PLANS TO REDUCE THE NUMBER OF OBSERVATIONS ON NEAS BRIGHTER THAN 22ND MAGNITUDE DUE TO THE NUMBER OF ACTIVE OBSERVERS THAT ARE FOCUSED ON THESE NEOS. IN 2015 ONLY SIX OBSERVATORIES REPORTED MORE THAN 250 22ND MAGNITUDE MEASURES OF NEOS TO THE MPC. OF THESE SIX ARI WAS RESPONSIBLE FOR 47.5 OF ALL THE OBSERVATIONS THAT WERE FAINTER THAN MAGNITUDE 22.0. IN 2015 H21 CONFIRMED 513 NEOS FOR THE SKY SURVEY DISCOVERY TEAMS AND RECOVERED TWENTY FIVE 22ND MAGNITUDE FIRST OPPOSITION OBJECTS. THREE OF THE FOUR INSTRUMENTS CURRENTLY IN OPERATION AT THE INSTITUTE ARE FULLY CAPABLE OF 22ND MAGNITUDE NEO OBSERVATIONS AND THE 1.3 M TELESCOPE IS CAPABLE OF RECOVERING 23RD MAGNITUDE NEOS. SHORTLY AFTER COMMISSIONING THE 1.3 M TELESCOPE IN SEPTEMBER 2014 NEO 2010 SV3 WAS RECOVERED AT UNFILTERED MAGNITUDE 24.2 WITH THREE MEASURES. THREE WEEKS LATER IT WAS CONFIRMED A SECOND TIME WITH THREE ADDITIONAL MEASURES. DURING THIS TELESCOPES FIRST 18 MONTHS OF OPERATION MORE THAN 105 23RD MAGNITUDE NEOS HAVE BEEN MEASURED.SIGNIFICANCE OF PROPOSED WORKOBSERVATIONS IN PHASE IV WILL BE EXTREMELY IMPORTANT ESPECIALLY DURING THE SUMMER MONTHS WHEN ONLY A FEW FOLLOW UP FACILITIES ARE AVAILABLE DUE TO THE SOUTHWESTERN U.S. ANNUAL MONSOON SEASON. IN 2015 THE INSTITUTE AT WESTFIELD ILLINOIS WORKED 63 NIGHTS DURING THE SUMMER PRODUCING 10 202 NEO MEASURES AND CONFIRMING 170 NEWLY DISCOVERED OBJECTS FOR THE DISCOVERY TEAMS. IN ADDITION H21 RECOVERED 163 NEOS THAT SUMMER FAINTER THAN MAGNITUDE 22.0.IN AN EFFORT TO STEP UP FAINT OBSERVATIONS ARO WILL CLEARLY IMPACT NASAS NEO PROGRAM BY TARGETING AN ESTIMATED 2 000 NEAS FAINTER THAN MAGNITUDE 22.0 EACH YEAR. IN ADDITION ARO ALSO PROJECTS THAT MORE THAN 250 INDIVIDUAL NEAS FAINTER THAN MAGNITUDE 23.0 WILL BE TARGETED EACH YEAR DURING THIS PHASE IV PROGRAM.
