I made an observation of the prominent walled plain Posidonius (95 km) at the border of Mare Serenitatis on November 2, 2004 (05:45-08:00 U.T.). I noted a significant amount of detail within the plain and surrounding regions. The Rimae Posidonius rille system was very prominent over the floor of the plain. The craters A and C are noted within the walled plain and J, B, and D along the upper (eastern) border. I welcome any comments that you may have on this observation.
The best of luck in your own observations and imaging of the planets and Moon.
