lunar occultation of Mars October 2003
- compare this with the July 2003 Florida occultation of Mars
This event seen as a grazing occultation in Melbourne with Mars so big is extremely rare!
The region from which an occultation was seen is limited by a grazing occultation of Mars at the north limb of the Moon. This occurred along a band some 50 km wide from Melbourne, through Canberra to Wollongong just south of Sydney. Areas to the south saw a full occultation.
note that the apparent size of Mars is approx. 75-100 x smaller than the moon
- the moon is approx. 400,000km from earth and has a diameter of 3,480km
- mars is approx. 60 million km from earth (150x further away) and has a diameter of 6,760km (only twice as big)
here are my pics of this event taken with a Canon S30 digital camera and a 10“ Newtonian telescope on 7th October 2003:
