Alessandro Dimai, Italian Amateur astronomer discovered his second supernova using the GRAS G15 remote telescope based in Australia.
GRAS (Global-Rent-a-scope) is proud to announce the discovery of a supernova SN2009bu close to NGC 7408
Alessandro Dimai, Cortina d'Ampezzo, Italy, on behalf of the CROSS program (cf. IAUC 7373), reports his discovery of an apparent supernova (mag about 16.4) on two unfiltered CCD images (limiting magnitude about 19.0) taken on Mar. 25.75 UT with the remote-controlled 0.28-m "GRAS15 telescope" at Moorook, Australia.
The new object is located at R.A. = 22h56m01s.40, Decl. = -63o41'39".6 (equinox 2000.0), which is about 18" east and 3" north of the nucleus of the galaxy NGC 7408. A CROSS image of the same field taken on 2008 Dec. 27.0 showed nothing at this position (limiting mag about 18.5), and it does not appear on Palomar Sky Survey infrared, red, and blue plates. The discovery image has been posted at http://www.cortinastelle.it/cross/NGC7408_20090325.jpg. SN 2007bn also appeared in NGC 7408 (cf. CBET 940).
To gain a greater insight as to how the GRAS remote astronomy network functions please click on the following link: GRAS Global Network Gateway. The GRAS information Center, is the gateway to the entire network and also provides access to many other functions of the global network (no obligation registration is required for access).
GRAS is the world's premiere Global Telescope Network. The GRAS Network provides access to some of the highest-quality, professional-grade scientific and imaging systems available today.
Over the last 5 years, GRAS subscribers have been deeply engaged in deep-space imaging, narrow-band deep-space imaging, research in areas like, asteroids, double-stars, variable stars, exoplanet, nova search, cannibalistic galaxies, gamma ray busters and comets. Many subscribers have published their own papers on their respective research.
Guided by our own research based support teams, GRAS members have collectively contributed thousands of observations to the many science information repositories around the globe.
Of special interest, GRAS Australia has just added the G11 AART to the rest of the arsenal of southern based observation stations. G11 has special CCD camera with a 12 position filter wheel. Available filters are LRGB - Imaging Filters, UBVRI - Photometric Filters and Ha, SII and OIII - Narrow Band Filters.
Many members of GRAS and the RAS Observatory routinely perform the following research activities: Astrometry, Photometry, CCD Imaging, Remote Astronomy, Robotic Astronomy, Supernova, Variable stars, doubles star research, binary star research, eclipsing variables, comet research, asteroid hunting, Astrophotography, Galaxies, Nebula, Planet, Space, Minor planets, deep space, Gamma Ray Bursters, Astroimaging, astroimager, photography
GRAS...for drivers, not passengers.
