Crater Bailly as drawn by Harry Roberts Here is the latest report from Harry Roberts, moon observer extraordinaire and member of the Sydney City Skywatchers: Harold Hill, the great lunar draftsman, says of Bailly “There is so much sketchable detail within this formation that it is well nigh impossible to cover Bailly in its entirety on a good night.” Bailly is hard to view since it lies on the western limb at latitude 66ºS, quite close to the lunar south pole, and Libration has a huge effect on how much of it we can view.

Crater Tycho Here is another drawing and observation of the Moon from Harry Roberts, Moon observer extraordinaire and member of the Sydney City Skywatchers: Tycho is a very young formation, only 110 million years old; much younger than the Sydney sandstone we walk around on.
To celebrate the Harvest Moon which throughout China marks the Mid Autumn Moon Festival, Sydney Observatory threw a party! Nearly 100 people came along to enjoy music, Chinese mythology, Moon cakes and of course telescope viewing.
Crater Hercules Sydney amateur astronomer, expert Moon observer and member of the Sydney City Skywatchers, Harry Roberts reports: High in the lunar NE we find a striking pair of fresh large craters, improbably named Atlas and Hercules: neither well known as men of science.
We have received many calls about an amazingly bright fireball over Sydney on Sunday night at around 7:00 to 8pm. Sadly this was not of heavenly origins but the RAAF!
Many of us have trouble finding the Southern Cross over the summer months. As a result many tourists get shown the "false cross", the "diamond cross" or one of many other asterisms out there that seem to resemble a cross.
The first quarter Moon This coming Saturday (30 September 2006) provides a final opportunity until 2025 to see the moon at its highest in the sky. From Sydney at 5:44 pm, just as the Sun is setting in the west, the moon will be due north and just five and a half degrees from the zenith, the point directly overhead.
If you and several friends would like a slightly different activity to enjoy one weekend read on! This photo was taken with a simple Canon Ixus camera, not an SLR or DSLR. Simply by holding the camera up to the eyepiece of our Solar Telescope I was able to take several images.
If you visit the website www.heavens-above.com and select your location, you can see predictions of when to look to the sky and see satellites, the International Space Station and Irridium flares like this one shown below.
This evening (Monday 18 August 2006) from 6:19 pm to 6:25 pm The International Space Station could be very clearly seen in the northern and north-eastern sky moving east. What made this a spectacular and memorable sight was a fainter accompanying point of light behind the ISS and keeping a constant distance from it.
Solar prominence on Friday 15 September 2006. Photo by Monty Leventhal Sydney amateur astronomer and expert solar observer Monty Leventhal has sent the above picture of a recent solar prominence. A prominence consists of gas thrown up from the visible surface of the Sun moving under the influence of magnetic fields on the Sun.
