lunar occultation of Mars October 2003

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:

0:15am camera zoom without telescope - getting closer!

2:38am - damn that's close!!
