Upper MW March Asteroids
I recommend going to this link for more information and maps.
Sorry, I've discontinued putting maps up for low probability events, If your interested in them please go to OccultWatcher. Tony George and Brad Timerson have kindly put up feeds for low probability events.
For Google maps and all the other information you need for the asteroid occultations that are on
Steve Prestons site, (larger maps and details) can be found on the site of Derek Breit along with station sorts, star charts and pre-point stars.
It is now easier than ever to find occultations near you with OccultWatcher you can see what events happen near you and announce your intentions.
The maps below are made from Steve Prestons FutureAll540.dat file. He generally updates the path anytime from 1 day to several weeks, usually a week or two before the event. Use these as a rough guide for pre-planning and keep an eye out on the above links for updates.
