So it is really a Pacific >Ocean/Pacific Rim event, visible throughout most of the Pacific, and >also from Japan and easternmost Asia, only the easternmost parts of >China. The event will be too low in southern and western Australia, >and southernmost New Zealand. >Local predictions for OCM6 are given at http://iota.jhuapl.edu for >the locations listed below; they use the July 24th CONTOUR orbit and >have an angular error of between 0.5 and 1.0 arc minute. I can >compute predictions for locations other than those listed below, >if you live 25 km or more from one of the listed locations (25 km >will result in less than a 2 arc minute error) >that are on the Web site, if your request is received before 10:30 >U.T. You can also obtain local predictions by requesting Object >CONTOUR at http://ssd.jpl.nasa.gov/cgi-bin/eph - the JPL Horizons >ephemeris Web site; they are using the latest orbit for CONTOUR. >The latest orbital elements for CONTOUR are given below, based >on the latest (July 26) orbit determined for the spacecraft and our >new calculations of the future maneuvers. >More about CONTOUR can be found at http://www.contour2002.org . >________________________________________________________________ > >Locations with topocentric predictions of OCM6 at >http://iota.jhuapl.edu > > San Diego, Calif. > Los Angeles, Calif. > Mt.
