It is then easy to work out the true time of each event from the notes made. The moon moves its own diameter in an hour, so the star might appear a surprising distance from the Moon at first. If you cannot find the star, check that you are looking near the correct lunar cusp. If necessary ask for help. Make sure well before the graze that your telescope is stable and at a comfortable height.
Radios often function better when off the ground and on a box or stool.
Make sure you are at the telescope, observing with maximum concentration, from at least three minutes before the central graze time predicted for your location, to at least three minutes afterwards. Remember that the mountains behind which the star will disappear are not usually sunlit, and hence cannot be seen. It is always possible for a star involved in a graze to be an undiscovered double. Hence always be prepared for unusual multiple events. This page was last updated on 11 March 1999.
