LUNAR SUNRISE/SUNSET CRATER RAYS
Background Information, Predictions Through 2010 and Observation Reports

[Be Sure to Click Your RELOAD/REFRESH Button to Show Most Current Information]

These events occur when the sun, at a low lunar altitude, projects a ray or spike of light, through a broken wall feature of a crater. Although many of these events may be visible on the surface of the moon, these are a listing of the more common ray events which have been reported in astronomical magazines, publications, or from observers who may have detected a ray for the first time, and reported it. Although not of any scientific value, the allusiveness of these events, coupled with the short time frame they are visible, make these real challenges for the avid lunar observer!

If you observe any of these events, and would like to have your observations placed in the reports, or if you think you have discovered another notable ray events, let me know and I will get it published here.

All the predictions are generated using Harry Jamieson's "lunar toolkit" program, which he distributes through the Association of Lunar and Planetary Observers (ALPO). The predictions are for only ONE location. That location used is the geographical center of the USA (W98.58, N39.83). Also by using only one location this will mean only ONE master database sorted to Date/Time order.There are many freeware, shareware and commercial programs to determine rise and set time for your location. When selecting a particular ray to observe, use these programs to determine whether the moon will be visible for your particular location. As an added feature I have now created an online database for 2004. See below for the link.

A word about using the table format: I have not provided links to "backup" from page to page. Therefore, use the RETURN/BACK button on your browser to return to the previous page!
