The third so-called supermoon for 2014 is about to happen. Supermoon is when Moon is at perigee to Earth. An eight year old explained perigee to me the other day. He said this is when the Moon is close to the Earth because of the slight oval path it takes around our planet.
Edinburgh is a fabulous city and on 24 May I managed to visit the time ball, located on Calton Hill, on top of a monument dedicated to naval hero Horatio Nelson. The monument is in the shape of an upturned telescope and was completed in 1816.
It hardly seems like two months since I flew into Alice Springs for a look around before the annular eclipse on Friday 10th May.

Let the astronomy begin! Considered the 'Astronomical Olympics' over 2,000 astronomers from around the globe gathered in Beijing last week for a fortnight exchanging ideas from research results and focussing on new scientific and heritage projects.
Post by Geoffrey Wyatt Calendars are attempts to try to keep track of time by using the cycles of the Sun ad the Moon. The Sun is used via the seasons and its changing position in the sky, for example the equinoxes and solstices.
This is the spot in the sky from where the Geminid meteors originate, known to astronomers as the radiant. Drawing Nick Lomb Every year at this time the Earth runs into a stream of dust circling the Sun.

by Stefan Tibar and Herve Meteyer On Sunday, 18th of July 2011, two young fellows from France have come to Sydney to renew the long French-English rivalry about the transit of Venus… Who, between French and British scientists could determine more accurately the distance between the earth and the sun using the observations made during the transit of Venus?
July 2011 marks a first in this country with the Australian Astro Imaging Conference held this month on the Gold Coast, Queensland. This is the first time a large scale conference on imaging has been held in this country, and with a full house, indicates the interest and need for a conference of this scale to be held on a regular basis.

Daphne Gonzalvez sent us this photograph she took from Bondi early on the morning of 28 May. Unfortunately, the parade of the planets was not visible over the next several mornings due to a cloudy sky.
Our two work experience students, Harry and Peter from Sydney Technical High School at Bexley used an avi file captured from a low cost security camera attached to a telescope to make this image of the beautiful nebula M42.
