All, welcome to my little corner of the Website, where I will be posting a little astro action and activities from my AARTScope Blog as well. Due to my association with iTelescope and through my blog, the Hubble Space telescope and ESO now follow me on twitter.

I regularly chase asteroids and work with Variable star observers so I'll keep you up to date on my activities.

Astronomy is a pursuit where everyone is so helpful and eager to share their knowledge, with the internet and a growing population of users, its a great scene to be a part of. 

My AARTScope blog is where I do most of my writing and occasionally host the Carnival of Space. AARTScope's mission is to "help create the sense of anticipation and discovery that keeps scientists asking questions".

AARTScope is quite deliberately a blend of Art and Science which highlights the full capabilities of T-011, as its great for the best of astrophotography and has already done some stellar science (if you pardon the pun).

Some of my most popular articles have been the Hyabusa Re-entry live blogging session where over 300 visitors from Asia and around the world joined the live blogging session. Recently I also did a great article for the ESO on Paranal and the visit of the world's first electric supercar.

I have also done a couple of interviews on Astronomy.FM including one on Photometry as a cloud service. Yep you read that correctly, is certainly on the cutting edge.

NACAA Sydney 2016 Day 2


After the magnificent meal in the Refectory to conclude day1 it was onto Day 2.

Day 2 was another smorgasboard of brilliant presentations from a wide range of topics. again spectroscopy featured in a number of great presentations. Some historic presentations including Ian SUllivan's great presentation on Frank Skjellerup and his comet studies.

A full list of the Day 2 program is here.

Solar observing, eclipse observations and dodging weather and travel difficulites gave us a good insight into the joys and pitfalls of eclipse tourism. Always having a backup plan, testing your equipment and your imaging workflows featured as excellent advice, for those planning future trips.

My own talk about the Career Path of a Teenage Asteroid Hunter, including the latest "infographic" of activities was well received by the attendees, including the surprise musical ending.

The final session of the afternoon, featured Donna Burton's subsequently Astral Award winning presentation "Dating active young stars". Jacquie Milner did a great presentation on handling all the interesting and tough questions asked by kids and parents at Outreach Events. Also the masters of precision, the Trans-Tasman Symposium on Occultation Timing began their workshop.

All in all it was a great time of celebration of Australian Amateur Astronomy, demonstrated the incredible skills and science capability of this diverse group of amazing people from Australia and New Zealand.

Special thanks again to Dr Padma Yanamandra-Fisher who came all the way from the US, and those who joined us remotely from Europe and North Queensland.

The final commentary is to wish all attendees safe travel to their homes, where ever that may be, and let you know that we'll be re-convening in BALLARAT, Victoria in 2018!





Osservatorio del Monte Baldo students recreate Leavitt's Cepheid study

One of's 2015 grant receipients Osservatorio del Monte Baldo run programs with students doing great research and helping young people connect with astronomy and the sciences. The results are in on their exceptional work which is featured in the Italian Magazine "Le Stelle".

Osservatorio del Monte Baldo student team has completed a brilliant observing campaign to recreate the work of Henrietta Swan Leavitt. The observatory based in Italy used's southern telescopes at Siding Spring Observatory to reach the Small Magellanic Cloud (SMC) a deep southern target. 

After the success achieved by students in 2014 with observations of M4 and creation of a Hertzsprung Russell diagram for the M4 globular cluster, the goal of the 2015 program at the Osservatorio, was to retrace the path outlined by H.S. Leavitt at Harvard and to study the classical Cepheids in the Small Magellanic Cloud (SMC).

In the students own words:

"To study SMC we obviously needed a telescope in the southern hemisphere (From the north of Italy SMC never rises!): fortunately, we could rely on the facilities that gave us the opportunity to use the telescopes placed at Siding Spring Observatory (Q62). In addition, the difference of 10 time zones between Italy and Australia allows us to use the telescope during school time." 

"To better simulate the observations of the beginning of the 20th century, we chose to use the T32 telescope (a 17-inch astrograph Planewawe f.6.8, equipped with a CCD FLI Proline 16803, giving a FOV of 43' * 43 '): the optical properties of this instrument and the clean sky of Siding Spring are comparable with those of the Bruce Telescope under the Peruvian sky originally employed, although exposure times of modern CCDs are shorter  than those needed for the historical glass plates of Harvard (minutes or tens of minutes vs. hours).

The data-taking sessions required took place between May and September 2015. The large FOV of T32 allowed  to include the images of all  the 16 Leavitt Chepeids within three fields. Each photographic field was recorded both with Vj and Ic photometric filters, in order  to obtain colour balanced light-curves.

Exposures were calibrated for the expected magnitude of the objects, from 120 seconds to 900 seconds in Ic and the same in Vj.
We chose the comparison stars for photometric calibration in the Apass catalog, converting the Sloan’s  gand  i' magnitudes into Ic  magnitude by means of the relation given in the article "Classical and Recurrent Novae"  (Munari, JAAVSO Volume 40, 2012582). Our s
tudents attended to the process all along its parts, from scheduling run to data analysis: they obtained  the light-curve, calculated the medium magnitude and plotted the Period / Magnitude graphic.

Even with the aid of modern technologies, it is still difficult to obtain good photometrical images of stars 200,000 light years faraway. For two of the observed Cepheids (those with the shorter period) we were not able to calculate the magnitude at the minimum, as they were confused in the sky background and nearby stars.

Apart from this difficulty, the overall result was very good; the equation period-luminosity obtained (not considering the extinction factor), was:

M = -2.781log(P)+17.76

As the equation presently accepted in literature is the following:

mv = -2.78log(P)-1.35

it can be easily checked that the slope has the same value, while the difference in intercepts depends on the distance and can be used with the distance module relation to calculate the distance for SMC. The result is then d = 66.5±5 kpc, in good agreement with the value of 61 kpc presently accepted." congratulates Erika, Federica, Ahmad, Davide, Diego, Eduardo, Gioele, Marco, Paolo, and their tutors: F. Castellani, F. de Sabata Ph.D. , R. Belligoli ; M. Sergio.

Your passion for the project, respect for the early female pioneers, the history, traditions and the science method is a fine example to all STEM Educators.

We look forward to your grant application for 2016.
