News from comet ISON

Comet C2012/S1 ISON: the brightest comet in the XXI century (so far) followed by GLORIA.

Comet ISON at dawn on November 21st (6:20 UT). The image was taken from the Teide Observatory (Instituto de Astrofísica de Canarias) with a digital camera (Canon 5D-MII, 85mm lens) and an exposure time of about 6 seconds. The brightest object in the image is the planet Mercury, while at the bottom center, just above the sea of ​​clouds, the peaks of the Gran Canaria island are visible. Credits: J.C. Casado,

On its way to the Sun, comet C2012/S1 ISON will continue to brighten, but it will also get harder and harder to see since it will be close to the Sun in the sky. Right now the comet is close to the eastern horizon before dawn. See the 3-D model.

On 25 March 2013 at 17:00 UTC, the first of 17 telescopes of the GLORIA (GLObal Robotic telescope Intelligent Array for e-Science) network was opened for free public access. This telescope, TAD (Telescopio Abierto Divulgación solar – “Open Solar Popularisation Telescope” is situated at Teide Observatory (Canaries Astrophysics Institute) in Tenerife and on the Web. Very soon, the second telescope, TELMA (TELescopio MAlaga – “Málaga Telescope”) will scrutinize the night sky at the BOOTES-2 station (EELM-CSIC) in Algarrobo Costa (Málaga) (

GLORIA Project

What is GLORIA?

GLORIA stands for “GLObal Robotic-telescopes Intelligent Array”. GLORIA will be the first free and open- access network of robotic telescopes in the world. It will be a Web 2.0 environment where users can do research in astronomy by observing with robotic telescopes, and/or by analysing data that other users have acquired with GLORIA, or from other free access databases, like the European Virtual Observatory (

Who and how can you access GLORIA?

The community is the most important part of GLORIA. If you are here it means you have an Internet connection and a web browser. Excellent! This means you can become a GLORIA user and be able to observe, and to perform experiments. In fact GLORIA is open to everybody with an interest in astronomy, not only to professional astronomers.
