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). But that does not mean necessarily that you cannot see an event from your location!
Also by using only one location this will mean only
ONE master database sorted to Date/Time order.(see below for the 2009 database download)
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 predictions to determine whether the moon will be visible for
your particular location. Hint: when planning an observation, it is advisable to
begin observing an hour or so BEFORE the predicted time.
