Voting Opens for IAU NameExoWorlds Competition

Good news, the International Astronomical Union has opened voting for their NameExoWorlds competition that MBO is participating in, having solicited suggestions from members of the public as part of National Science Week 2014.

In June Mount Burnett Observatory selected the names "Ezu" and "Heroicos" from those suggestions as its submission to the competition for the star xi Aquilae and its exoplanet xi Aquilae b, and you can vote for them (if you wish to do so!).

Presidents Message: An important message about the car park

Dear Mount Burnettichi
Winter is not just coming, it has arrived in its full splendour. At Mount Burnett that means cold nights and lots of rain. Rain means boggy car parking. This makes it a good time to discuss access to MBO.
If the gate is closed then MBO is closed.
For the sake of safety ONLY COMMITTEE MEMBERS AND OUTREACH TEAM LEADERS are permitted to open the gate. During the winter months we want to check the state of the car park before members and visitors arrive. Bollards and tape will be put up around boggy areas so please leave them in place should you see them. If you arrive early for a session please be patient and wait at the gate.
Those of you who have been members from the beginning will remember how rapidly the car park deteriorated that first winter, leading to closure of Mount Burnett for several weeks. Rather than repeat that occurrence we ask everybody’s patience and assistance.
Yours in wellies,


Wednesday 1st & Thursday 2nd July - Venus and Jupiter Conjunction

In the early evenings of Wednesday 1st and Thursday 2nd July Melbourne will be treated (weather permitting) to a lovely conjunction of Venus and Jupiter in the north-western sky, less than a degree apart (closest on Wednesday night). Here is how the excellent free software program Stellarium shows it (click for full size images).
