Recently, I wrote an article that was published in _Selenology Today_, Issue No. 13, on the upcoming LCROSS mission to impact a spent Centaur booster in a permanently shadowed area of one of the lunar poles. The resulting ejecta cloud might be visible for amateur earth based telescopes. The article might provide some snooze time reading during the current string of cloudy nights. Fisher, Kurt A.

The LCROSS impact is shaping up to be something like the Smart-1 impact a couple of years ago. The Moon probably will be too low on the Utah horizon to effectively follow the event. But the mission parameters are in flux and it is still possible that the impact will occur later in the year and when the Moon is higher in the sky. I'm still holding out some hope for the latter, since the major ground based observatories are in New Mexico, Arizona and Hawaii. It would make more sense for the impact to occur when the Moon is high in those northern hemisphere observatories's skies. Clear Skies, Kurt
