F-111 dump & burn at the Richmond Air Show 2006, courtesy Department of Defence Many people reported a bright fireball over Sydney on the evening of Australia Day. My colleague Geoff Wyatt did suggest that it was a dump and burn from an F-111, but some people were not fully convinced.
Sydney at night, photo by Nick Lomb A major city like Sydney needs to be lit both in its CBD and in its suburbs, but how much light do we need? Does more light make it safer on the streets? Does more light make it easier to see?

Comet McNaught continues to be visible although it is fading. Now however, it can be seen in the morning sky in the South East from around 3:45am until morning twilight at around 5:15am. These images were taken at Echo Point Katoomba just a few hours ago.

The Sun on Monday 29 January 2007, courtesy Monty Leventhal Comet McNaught maybe fading, so it maybe time to consider another celestial body that is not fading. And it is unlikely to fade unless a rather worrying US scheme to block some of the Sun's light actually eventuates.
Well after a fabulous day at Sydney Observatory celebrating Australia Day I headed to Katoomba with my friend Dr Paul. We found a lovely spot a snapped a few images. In the last one you can see a bright satellite trail which is the International Space Station.
Thankyou to the 1400 plus people that came to Sydney Observatory today for our Australia Day program. We launched rockets, in our national colours of green and gold of course. And to farewell Pluto from our family of planets, we made Arriverderci Pluto hats.
Hello All, If you would like to have your name, or those of your family, sent to Mars with the Phoenix lander mission, you can submit names for inclusion on a DVD that will be carried on the lander via the Planetary Society's website at http://planetary.org/namestomars Submitting your name will enable you to print out your own certificate of participation, to commemorate your inclusion on this historic mission.
Despite starting to fade quickly this beautiful comet continues to delight us all. So much so that we are now getting photos sent to us at Sydney Observatory. Here is just a sample. Of course if you have a cool comet shot please send it to me at email@example.com in jpeg format with a width of 400 pixels and I'll add it to the collection.
With all the excitement around Comet McNaught (see Geoff Wyatt’s unbelievably stunning images below) it should be remembered that there are other things of interest in astronomy at the moment. One is the status of Pluto that was discussed in an infomative debate at Sydney Observatory in front of a capacity crowd of over 120 or so people on Saturday evening.
