Key to Images in this Issue 90

In this issue of The Lunar Observer, you will find a wide variety of lunar topics discussed, including topo-graphic forays by Rik Hill, Robert Hayes, Jr. and David Teske. Sergio Babino and Alberto Anunziato ex-plore lunar geologic change with an in-depth study of bright spots seen in crater Mutus F, as discussed in last month’s Lunar Geologic Change by Tony Cook. Tony Cook brings us another in-depth discussion about Lunar Geologic Change this month. A few new things to be on the look-out for. On page 6, you will see “By the Numbers” about our observ-ers locations, observations and telescopes. Also, if you have not yet heard of the book Luna Cognita by Robert Garfinkle, check it out! Also, the USGS published a new lunar map, available at https://www.usgs.gov/news/usgs-releases-first-ever-comprehensive-geologic-map-moon which is really nice!

Anthony Cook comenta una observación de Alberto Anunziato de Eimmart para compararla con reporte de FLT de 1981:

Figure 7. The bright spot on the western wall of Eimmart crater as sketched by Alberto Anunziato (SLA) on 2020 Apr 03 UT 23:30-23:40. This sketch has been reoriented so that north was towards the top and labels adjusted accord-ingly.
