Below is a list of Minor Planet Electronic Circulars (MPECS) co-authored by the Winer Director, Mark Trueblood, his colleague Robert Crawford (Director of the Rincon Ranch Observatory), or both. The NEOCP MPECs are shown when one queries the Astrophysics Data System and checks the IAUC box. The Daily Orbit Update (DOU) MPECs contain the observations of dozens if not a hundred or more observers, so co-authorship is not given. Therefore, DOUs are not searchable by author on the ADS.
However, the observations in the DOUs are usually of Virtual Impactors (VIs) and Potentially Hazardous Asteroids (PHAs), objects with an enhanced probability of striking Earth, as opposed to the vast majority of NEOs. The observations in a DOU reduce the uncertainties in the orbits of VIs and PHAs, and help assessments of their impact probabilities.
In the MPECs, the Winer Observatory Sonoita Field Station in Sonoita, AZ has IAU Observatory Code 648. These MPECs were co-authored by Trueblood and Crawford. Trueblood (as PI) was also awarded time on the Kitt Peak 2.1-m and 0.9-m telescopes to perform astrometric follow-up of NEOs using observatory code 695. Dr. Larry Lebofsky assisted us on the 2.1-m runs, with others (Tom Kaye, Dave Bell) filling in from time to time as needed.
