    I observed the Waning Gibbous Moon (ascending) this morning from around 03:15 BST to 05:00 (Transit: 02:07). Azimuth 17.1° S, altitude 20.8°, 98.5% illumination (Aquarius). Conditions were slightly above average and the transparency was often quite good. With a little occasional hazy cloud.

    Magnifications ranged from 60x, 82x, 112.5x, 150x, 180x, 257x and 281x. A Baader Neodymium filter was used predominantly.

    Most observing was near the Terminator, as would be expected at this phase. The Sea of Crises and the Sea of Fertility were both quite stunningly clear even at high magnification. Petavius and Langrenus were easily defined. The central mountain in Petavius could distinctly be seen although the Rimae Petavius was not so apparent.

    Transparency was above average. Magnifications included 150x, 204.5x, 225 and 281x.

    Mare Nectaris was quite prominent and the Daguerre ‘ghost crater’ could easily be perceived. The Reichenbach crater region was very defined.

    The Atlas and Hercules craters were very well contrasted against the lunar surface.
