Is this the end of comet ISON?
Comet ISON has failed to survive its perihelion intact? Yes, but something is still there.
A few signs of unhealthy behaviour were observed in the days before it made its closest approach to the Sun. Being so close to the Sun must have been very “stressful” and what is left (see image) could disappear to our eyes very soon. For the time being, let’s keep watching.
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, iac.es.
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.

A very difficult, and in part unlucky expedition, is coming to its end. You’ll read a full report about it on this site soon. For the moment enjoy some of the pictures collected at our Flick website and watch the time-lapse video of the observing site landscape below. More to come.
Edited HD video is here.

The lions sleep… today. Yes it’s true. On the 3rd of November 2013 a total solar eclipse will cross Central Africa, and some adventurous GLORIA team members will take a walk on the wild East side of Turkana Lake in Kenya to record and broadcast the event live (see below for details). This UNESCO World Heritage Site is also known as the cradle of humanity. Our ancestors could not predict the occurrence of eclipses as we do. However, even armed with our scientific knowledge, the experience of an eclipse remains as spectacular to us as it must have been for them. The fact that this one is occurring during the year of maximum solar activity, holds the promise of a particularly lovely spectacle to the privileged watchers.

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 (http://www.euro-vo.org).
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.
Landscape view from Leif Eriksson Hostel in Quassiarsuk, South Greenland. In the distance, the Narsarsuaq airport and some icebergs coming from the Qoroq glacier. This is the site of the August 28th live webcast of the Aurora.
The team of 15 people of the Shelios 2013 expedition arrived to Narsarsuaq, Greenland, on August 22nd. After visiting the camp sites in the Qaleraliq glacier and the Tasiusaq village, today (Aug. 28th) we arrived to Leif Eriksson Hostel (Tasermiut - http://www.tierraspolares.es) located in Quassiarsuk. In front of us Narsarsuaq airport and some icebergs (see the picture).
With some difficulties due to the bad weather, on arrival at the observation sites we set up and tested the satellite connection and put in place all our cameras. On the 24th everything was ready … but the sky was almost always cloudy and the temperature around 3 degrees.
Sky only partly visible on the 22nd, day of arrival, and then, as you can see from our twits, we had to wait until the night of the 26th to get a clear night. A night good for the live transmission and fabulous to take spectacular pictures. Have a look for example to this Flickr set and to this YouTube video.
Some photos of the expedition are available at here
Today, August 28th the day is sunny and weather forecast for the night is good. In a few hours the “aurora dancing” will cover the skies.
