QR-code providing the data of the exact location, which is important for the calculation of the lunar limb. The « Sea Urchin Diagram » giving the lunar-limb profile in a polar plot has been prepared by Cédric Willemin, based on the data and sofware Occult provided by Dave Herald (Murrumbateman, Australia).
The precise topocentric lunar librations for that location and date are: L=-2.11°, B=-0.64°, C=357.07°.
