Cook 82 Key to Images in this Issue 88 This issue features a number of very interesting articles about the Moon including the very popular Focus- On Lunar Targets by Jerry Hubbell. Howard Eskildsen and Robert Hays, Jr. added articles that compli- mented these Focus-On targets. The apparent size of the Moon is explored in two articles by Victor Cabrera and Diana Teyssier. Alberto Anunziato and Sergio Babino highlight various lunar targets, as does Rik Hill. Raffaello Lena allowed some of his wonderful lunar dome research to grace our pages. As al- ways, Tony Cook presents a thorough and interesting Lunar Geologic Change Detection article. Howard Eskildsen has begun research again in the ALPO Banded Craters Program. Many thanks to all contribu- tors here.

The Lunar Observer is a publication of the Association of Lunar and Planetary Observers that is available for access and participation by non- members free of charge, but there is more to the A.L.P.O. than a monthly lunar newsletter. If you are a nonmember you are invited to join our organization for its many other advantages. We have sections devoted to the observation of all types of bodies found in our solar system. Section coordinators collect and study members’ observations, correspond with observers, encourage beginners, and contribute reports to our Jour- nal at appropriate intervals. Our quarterly journal, The Journal of the Association of Lunar and Planetary Observers-The Strolling Astronomer, contains the results of the many observing programs which we sponsor including the drawings and images produced by indi- vidual amateurs. Additional information about the A.L.P.O. and its Journal is on-line at: http://www.alpo-astronomy.org. I invite you to spend a few minutes browsing the Section Pages to learn more about the fine work being done by your fellow amateur astronomers. To learn more about membership in the A.L.P.O. go to: http://www.alpo- astronomy.org/main/member.html which now also provides links so that you can enroll and pay your membership dues online.

The Lunar Observer/November 2020/ 4 November 2020 The Lunar Observer By the Numbers This month there were 78 observations by 22 countries in 7 countries. The Lunar Observer/November 2020/ 5 SUBMISSION THROUGH THE ALPO IMAGE ARCHIVE ALPO’s archives go back many years and preserve the many observations and reports made by am- ateur astronomers. ALPO’s galleries allow you to see on-line the thumbnail images of the submitted pictures/observations, as well as full size versions. It now is as simple as sending an email to include your images in the archives. Simply attach the image to an email addressed to [email protected] (lunar images). It is helpful if the filenames follow the naming convention : FEATURE-NAME_YYYY-MM-DD-HHMM.ext YYYY {0..9} Year MM {0..9} Month DD {0..9} Day HH {0..9} Hour (UT) MM {0..9} Minute (UT) .ext (file type extension) (NO spaces or special characters other than “_” or “-”. Spaces within a feature name should be replaced by “-”.) As an example the following file name would be a valid filename: Sinus-Iridum_2018-04-25-0916.jpg (Feature Sinus Iridum, Year 2018, Month April, Day 25, UT Time 09 hr16 min) Additional information requested for lunar images (next page) should, if possible, be included on the image. Alternatively, include the information in the submittal e-mail, and/or in the file name (in which case, the coordinator will superimpose it on the image before archiving).
