Entries in Rolando Ligustri (10)


Comet Siding Spring - Tours the Southern Skies

As Comet C/2013 A1 Siding Spring glides towards its encounter with Mars in October, it’s passing by some major deep sky objects in the glorious south celestial sky. iTelescope members weren’t going to let the comet’s picturesque alignments pass without action. 

C/2013 was discovered on 3 January 2013 by Robert H. McNaught at Siding Spring Observatory using the 0.5-meter (20 in) Uppsala Southern Schmidt Telescope.

iTelescope veteran Rolando Ligustri captured this unique portrait using the T12 iTelescope at SSO observatory during the night of August 29th. It shows the rich assemblage of stars and star clusters that comprise the Small Magellanic Cloud, one of the Milky Way’s satellite galaxies located 200,000 light years away.

Looking like a fuzzy caterpillar, Siding Spring seems to crawl between the rich swarm called  47 Tucanae, one of the few globular clusters bright enough to see with the naked eye and the SMC. C/2013 A1 is currently circumpolar from many locations south of the equator and visible all night long from our own Siding Spring based iTelescope observatory.

Comet Siding Spring's encounters and path is also further detailed in Ian Musgrave's "SkyAlerts" blog


The Year of the Comet - Nicole's Universe

If there were such thing as an Astronomical Calendar, last year would have been the “Year of the Sun” following the total solar eclipse, the annular eclipse and the Transit of Venus. And this year it would be the “Year of the Comet.”

Comet C/2011 L4 (or just Comet Pan-STARRS), was discovered by the Pan-STARRS 1 telescope in Haleakala, Hawaii, and first made an appearance in the southern hemisphere in 2012. People were treated to a spectacular show as the comet neared an estimated brightness of around +1. People in the northern hemisphere enjoyed Pan-STARRS in March 2013...



iTelescope SSO - Images of NEO 2012 DA14

During the clear pre-dawn hours of February 15th UTC 2013, the huge steel roof above the iTelescopes at Siding Spring Observatory (SSO) Australia, was remotely opened by its site manager (the roof was closed due to very high humiidty during much of the night) to allow a difficult mission for some of its more experienced members to begin. Capturing the closest ever flyby of a large NEO or Near Earth Object. A very large asteroid the size of the Space Shuttle was about to zip past us all, approaching Earth from the far southern skies during the next few hours. 

JPL/NASABeginning at around 0430hrs SSO local time all of the telescopes had astronomers quickly running their preset observing plans and begin slews to locations in the far southern skies. Starting the nervous wait for the bright and quickly moving NEO to pass into the fields of CCD cameras, sitting cooled and ready for action.

One of the first was Rolando Ligustri based in Italy. He took control of T30, a half meter reflector, and skillfully captured the NEO in a series of short sub-exposures which he combined to create the image below of the tumbling asteroid's path among the stars over Australia.

R.Ligustri - T30 SSO iTelescope Facebook site became a central channel of exchange with many of its members swapping sightings, images and information as hundreds of megabytes of data from the iTelescope SSO systems became available shortly after closest approach. Among them were astronomers Nick Howes (England) and Ernesto Guido (Italy) , members of the Remanzacco Observatory Team also based in Italy, which excels in the dark art of asteroid and comet chasing.

This early animated image (left) was posted by Nick & Ernesto to Facebook and immediately drew the attention of NASA. Both of them very excited and eager to spread word of the Remanzacco team's success in imaging the rocky visitor.

"2012 DA14 at closest approach earlier was steaming along at almost 6.6km/s. Want to get an idea just how fast that is? These are 5 second exposures!"

Then soon afterwards..

"Oh my GOD we made NASA homepage AGAIN! This time with OUR images and animation from iTelescope's superb network of scopes. Ernesto and I are thrilled beyond belief!"

The Remanzacco team's images were widely used by the press and NASA allowing the very curious general public and amateur astronomy community around the world see the closest shave the Earth has had with a large asteroid in recent history.

"Our images taken with the iTelescope network scopes last night of asteroid 2012 DA14 were just on the BBC main headline news, on BBC News 24 and Dutch TV."

Nick and Ernesto were happy to give us an insight into the Remanzacco Observatories team goals and aspirations.  "We try our best always as a team to provide not only solid science with astrometry and photometry with data fed in to the CARA program on comets, but also, we try our best to say thank you to the itelescope team by promoting their great facilities so that it encourages others, in particular young people/students to try them."

"NOTHING makes me happier than hearing just one student say "you know... I think I'd like to try that" and maybe we've encourage the spark in them to become a future astronomer. After the loss of our friend and team member Giovanni last year, we've redoubled our efforts on this cause too." another amazing image was captured by Aaron Kingery for NASA/MSFC. The image below shows asteroid 2012 DA14 and the southern Eta Carinae Nebula. The white box highlights the asteroid's path. The image was taken using the one shot color CCD on iTelescope T13 also located at the Siding Spring Observatory in Australia. This image was also featured on the NASA Homepage.

On the 17th and 18th Feb, Peter Lake ran several sessions on 2012 DA14 reporting 54 positions to the Minor Planet Center and photometry to the OSIRIS-Rex Project. 

It was a great night for remote amateur astronomy and we would like to thank all those involved in helping the world see the wonders of the universe both near and far.
