Mount Burnett Observatory Open Day – 23rd February 2016 – noon until late!

If you’re around Melbourne, interested in astronomy and fancy visiting a community powered astronomical observatory that has a very active outreach and amateur astronomy focus then can I interest you in the Mount Burnett Observatory open day this Saturday (January 23rd) from noon onwards?

We’re going to have all sorts of things going on – talks, telescopes, radio astronomy, tours of the observatory dome (originally built by Monash University), lots of enthusiastic volunteers!

We’re fundraising to build a new accessible modern dome to complement the existing facilities so please come and help us out.

Mount Burnett Observatory Open Day and Third Birthday – Saturday 24th January 2015

As some of you know I’m involved with the Mount Burnett Observatory, a community run astronomical observatory in the Dandenong Ranges of Victoria near Emerald to the south-east of Melbourne. Originally built by Monash University in the early 1970’s it’s 3 years since a small group of people formed a community association, took over the site and starting resurrecting it as an observatory by and for the people. It’s now three years on and by the end of last year we were the second largest astronomical association in Victoria!


This Saturday (24th January) is our third birthday celebration so we’re having an open day running from 1pm through to 6pm with tours, activities, a solar telescope and components from the Murchison Widefield Array (MWA), one of the precursor telescopes to the massive Square Kilometer Array telescope project!

At 6pm we have a barbecue and then at 7pm there will be a talk by Perry Vlahos on what there will be to see in the sky over the coming month. After that we’ll be socialising and, if the weather behaves itself, viewing the stars through the many observatory telescopes.


How Far We Have Come: Comets

In 1986 ESA’s Giotto mission visited Comet Halley and I watched Patrick Moore on the BBC as the first images of a comets nucleus were returned.

Now it’s 28 years later and the ESA mission Rosetta has just arrived at 67P/Churyumov-Gerasimenko, and the difference in imagery is just amazing – and this isn’t even the full resolution version!

Lunar Eclipse 15th April 2014

Tonight Melbourne got to experience the tail end of a lunar eclipse as the moon rose in eclipse at 17:48. We took a friend on a trip up to the (apparently now closed) Olinda Golf Course to view the moon rise. It was nice and clear and after roaming around a bit to find a place where we should have been able to see the eclipsed moon we found a suitable spot but couldn’t see the moon itself. Mars was visible in the right area but of course the salient point of a lunar eclipse is that the moon is in the earths shadow and so wasn’t findable until it started to exit at third contact. Got a few photos, of which this was the best.

We had to head back down the hill as Donna had an appointment at 7pm but later on our friend called up and said excitedly “Have you seen the moon? Go and look!”. I went out to see but the hills were still in the way then, so later on I headed out with the camera once the moon was visible and got some more photos as the moon headed towards fourth contact (when it exits the shadow of the Earth).

Mount Burnett Observatory Second Birthday & Open Day

Just over a week ago it was the Mount Burnett Observatory’s second birthday, celebrating two years since being reopened as a community observatory. Originally it was built by Monash University and used as a research and teaching observatory until becoming surplus to requirements. A group of people made a community association to take up the lease after the Astronomical Society of Victoria passed it over and now it’s the third largest astronomical society in Victoria!

Preparing for the Mount Burnett Observatory Open Day 2014 Mount Burnett Observatory Dome

To celebrate being two years old MBO held an open day running from 10am until 6pm when there was an open barbecue followed by a talk by Prof. Sarah Maddison from Swinburne University. We really didn’t know what to expect in terms of turn out but were amazed to see our first visitors arrive before we opened at 10am! I helped out demonstrating the large 18″ telescope in the dome until 12:30pm when I had to head home, at that stage we’d had 30 people through. I was struck by the number of people who were amazed they had no idea that there was an observatory on their doorstep, let alone one they could join and participate in. One person asked how much it was to join and when told it was just $50 for the year said “I spend more than that on astronomy magazines every year!”. 😉

It was a very successful day with well over 100 non-members visiting the observatory during the day, plus of course many members. It was certainly a packed club house for the talk that night! I donated two bottles of sparkling wine for a door prize, one of which was one by a member (and volunteer for the day) and one was one by a visitor. The only disappointment of the day was that we had cloud that night, so there wasn’t really much to see in the sky.

It was very good to see that the following Friday we had over 30 people attend the regular Friday night members night and probably about half were new faces.
