2019-08 TLO available
The August 2019 issue of The Lunar Observer, newsletter of the ALPO Lunar Topographical Studies & Selected Areas Program, and the Lunar Geological Change program is available at http://moon.scopesandscapes.com/tlo. Back issues and additional program information are also available at http://moon.scopesandscapes.com. This issue includes several contributed articles and an announcement of a change of coordinators for the ALPO Lunar Topographical Studies & Selected Areas Program.
After almost 11 years in this position, I have resigned as coordinator. David Teske has agreed to take over the Coordinator position and editorship of the TLO. He was officially appointed by the ALPO Board at the July meeting and, with this issue of the TLO, he has fully assumed his duties. I will continue as assistant coordinator, primarily entering observations into the ALPO gallery. All observations should now be submitted to david.teske@alpo-astronomy.org, as well as submitting copies to assistant coordinators, wayne.bailey@alpo-astronomy.org and jerry.hubbell@alpo-astronomy.org. As has been described in recent issues of the TLO, the easiest way to do this is to send the email to lunar@alpo-astronomy.org which will automatically forward it to all relevant recipients. I’ve enjoyed my 10+ years as coordinator and appreciate all the support I’ve received. I’m certain that David will do an excellent job and bring some new ideas to the program.

More GRAIL info
More information about the upcoming GRAIL impacts is also available at
http://www.spaceflight101.com/grail-mission-updates.html
The impacts will occur at 22:29 UT, seperated by 20 seconds. The spacecraft are small, so nothing is expected to be visible, although the impact occurs in the dark. Because it’s waxing crescent, it will be daylight or twilight in most locations where the moon is above the horizon. LRO will image the site both before and after impact.
Thanks again to Mike Mattei for pointing out this web-site.
NASA live commentary during GRAIL impact
Mike Mattei brought this announcement of live commentary during the impact of the GRAIL spacecraft to my attention. The site for the impacts is near the northern crater Goldschmidt, which will be in darkness at the time.
