This Monday evening will be a great time to view the Moon as it is at first quarter phase, the phase when most detail is visible. The amateur group Sydney City Skywatchers will hold a Moon observing practical night at Sydney Observatory on Monday 3 July at 6:30 pm. If the sky is clear there will be Moon observing led by the experienced amateur Harry Roberts while if it is cloudy Harry will do a presentation illustrated with his detailed drawings. There will be a charge of $2 per person which includes supper. All welcome and no bookings are needed, but it would be a good idea to contact the secretary Elizabeth on 02 9398 9705 before coming.
