This is a Mercury drawing around 17:20 UT.of April 17
        for 10 minutes the seeing was I-II Ant. so was possible to observe Mercury with
        400X .
        I used w21 filter.
        In the best moments of seeing I Ant., some bright and dark features were visible.
        Solitudo Phoenicis and Solitudo Atlantis were dark. The Liguria area and the South
        Polar Region bright. 3 other unnamed circular bright areas were visible. The first
        around approx. lat -10°and long. 190°  the other two toward the terminator approx.
        to lat.-30° long. 250°  and lat.+10° long. 250°.

        Kind regards
