After two weeks from its last sight, the Virtual Telescope spied again supernova SN 2013am, recently discovered in the bright galaxy Messier 65. The sky was very dark, so the vision was particularly good. Images were captured, as usual, remotely using the 17″ robotic unit part of the Virtual Telescope Project.
The supernova is still shining as bright as it was last 28 April.
The Virtual Telescope visited for the 4th time supernova SN 2013am, recently discovered in the bright galaxy Messier 65. The Moon was very bright and the sky was hazy, but the star was well visible in all the raw images captured by the 17″ robotic unit part of the Virtual Telescope Project.
Its brightness looks unchanged, but the Moon was strong, so new images will be taken as soon as the sky will be darker.
Last 14 April, the Virtual Telescope hosted an online star party, organized by the Northern Virginia Astronomy Club (NOVAC). It was also opened to all those willing to join it online. While the telescope and the “driver” (dr. Gianluca Masi, astrophysicist at Virtual Telescope Project) were in Italy, the NOVAC friends enjoyed online the real-time images taken by the PlaneWave 17 robotic unit and commented by dr. Masi.
The sky was just amazing, very clear and steady and images turned out to be unforgettable. The truly outstanding performance of the system made possible to capture great views of some of the most beautiful deep sky gems in the Spring, northern skies.
Participants reached a distance of 40 millions or so of light years, spying the wonderful galaxy Messier 65, these days hosting a bonus: a supernova (SN 2013am), discovered a few weeks earlier.
Then, it was time to visit Messier 51, the “Whirlpool”: always a breathtaking view, with the perfection of the spiral design and the presence of its companion. M 51 is one of the most beautiful galaxies out there.
Then, a quick leap into Ursa Major, to see the irregular galaxy Messier 82, the “cigar”. Plenty of details in its intrigued profile, with a lot of dust and fine structures, exalting the image resolution and quality of the vision.
Back and forth into deep space, we slewed the scope to a true gem: the bright, astonishing globular cluster in Hercules, Messier 13. Just a couple of seconds of exposure gave a clear evidence of its richness. A deeper view showed literally countless stars, one of the greatest hits of the season.
Heading east, we entered the Summer skies with a look at Messier 57, wondering about the destiny of our own Sun. That dying star showed very easily, as well as the far galaxy apparently sharing the same area of the sky, but incredibly farthest.
The final destination was the NGC 4565, a venerable edge-on spiral, like a blade of light with its prominent bulge.
A great adventure, as always when the sky is involved. We wish to thank all the friends of the Northern Virginia Astronomy Club (NOVAC), in particular David Werth and Phil Wherry, for considering the Virtual Telescope for their great and very successful event!
A supernova was recently discovered in the bright galaxy Messier 65; the Virtual Telescope helped confirming it while it was still waiting for an official designation. It is named SN 2013am and resulted to be a type II supernova, found when it was very young.
The unusually cloudy season offered a clear night on 3 Apr. 2013, when the 17″ robotic unit part of the Virtual Telescope Project was slewed to image M65, under dark sky conditions.
The exploding star was clearly visible on each raw image and an average of several of them makes it very evident. Its brightness is similar to Mar 28.
As you know, a supernova was recently discovered in the bright galaxy Messier 65; the Virtual Telescope helped confirming it while it was still waiting for an official designation. Now, it is named SN 2013am and resulted to be a type II supernova, found when it was very young.
Unusually cloudy weather made almost impossible for us to provide further follow-up, but the sky finally cooperated on 27 Mar. 2013, when it was clear for about 30 minutes (thanks, clouds!). Promptly, the 17″ robotic unit part of the Virtual Telescope Project was slewed to image M65, while the full Moon was about 30 deg far, making a very bright sky.
The exploding star was clearly visible on each raw image and an average of several of them makes it very evident. Its brightness increased just a bit since the discovery, very likely suggesting this supernova is highly obscured (otherwise, it should much brighter).
On 21.637 Mar. 2013, M. Sugano, Kakogawa, Hyogo-ken, Japan reported the discovery of an apparent supernova in Messier M65. The candidate was published on the Transient Object Confirmation Page of the Central Bureau for Astronomical Telegrams.
The Virtual Telescope Project contributed to its confirmation, providing photometry and astrometry for the SN suspect. Later, the object received its official designation, SN 2013am (CBET 3440). The Moon was bright and close at the imaging time. Here it is another image of Messier 65, without the supernova.
Below is the supernova in real timer, while it was observed for confirmation.
Messier 65 (NGC 3623) is a spiral galaxy in Leo, located at about 35 millions of light years, part of the so-called “Leo’s Triplet” (with M66 and NGC 3628 ). It was by C. Messier on March 1, 1780. Here, it was imaged with the Planewave 17, part of the Virtual Telescope Project. A total of 14 exposures, with 5 minutes of integration each, were averaged. Images were unguided, completely trusting the Paramount ME mount. The CCD camera is a SBIG STL-6303E. The image scale is of 0.78 “/pixel. Image by Gianluca Masi.
