Minor Planet Center By: Christie Nurkowski
What is MPC? • Based at the Smithsonian Astrophysical Observatory • It designates minor bodies in our solar system • It collect information and publicizes it
What do you observe? • Minor Planets (asteroids) • Comets (with the CBAT) • Natural Satellites (with the CBAT)
Equipment Needed to Observe • A telescope (reflector/refractor) • A computer with a CD-ROM drive • A clock or watch set to UTC • Guide Star Catalogue software
Jordan Hall • Will be your permanent site • Obtain an observatory code
Beginning Observers • Start with average sized objects • Observe more than one at a time • Observe objects of various brightness • Gain experience before moving to more “unusual objects”
Observations • Observe over two nights or as closely as possible • Two or three observations per each object • Observe for about an hour • Your initial batch contains two nights of observation of more than one numbered minor planet
Reporting Information • Special format • State only one position for each observation • Report positions of objects in your images • Required to include • Observer • Measurer • Telescope details
First Time Submitting Astrometric Observations • You must report: • A snail mail address • Observatory name and site • Longitude (degrees, minutes, and seconds) • Latitude (degrees, minutes, and seconds) • Altitude (meters above sea-level) • Details of telescope set up • First batch of observations
Sending Information In • Mostly sent in by e-mail • Astrometric (minor planets) emailed to MPC – mpc@cfa.harvard.edu • Comets emailed to CBAT – cbat@cfa.harvard.edu
Observations Processed by MPC • MPC will send you a notice • Look at observations when resources are available • Go in order in which observations are received
