Grazing Occultation Maps for North America

Interactive Maps of Event Paths
Included Time File gives times along the graze path.
Email me for Profiles for longitude positions and elevations along the path.
Use the Offsets on the maps to adjust location based on the Profile.
At the links below, you will be directed to Google Maps of the event.
This is an interactive map allowing you to zoom in on your location and find road intersections at which observing stations can be located.
I appreciate the help of Derek Breit and Kiwi Geoff Hitchcox in helping me get these pages published.

New Procedures to Report Total and Grazing Lunar Occultations

The International Occultation Timing Association (IOTA) analyzes lunar occultation observations and is now the world clearinghouse for such observations, having taken over this role from the International Lunar Occultation Centre (ILOC), which will close in March 2009. Because of this, new procedures have been established to aid observers in reporting their observations.

Two new ways (in addition to using OCCULT4 directly and LOW - Lunar Occultation Workbench) are being readied to report lunar occultations. One method uses an Excel Report Form similar to the Form in widespread use in the reporting of Asteroid Occultations. Those familiar and comfortable with the use of the Asteroid Report Form may want to give this new Lunar Report Form a try. The other procedure uses an application developed by Dave Herald called LunarReport which looks very much like the module used in OCCULT4 to enter observations.
