Keeping an Eye on Volcanic Ash
ESA and EUMETSAT recently organised a workshop in Frascati, Italy (May 2010) for more than 50 experts on volcanic ash from around the world to take stock of what has been learned about ash cloud detection, monitoring and prediction, and identify future opportunities. The workshop was convened following the recent ash clouds from Iceland’s Eyjafjälla volcano that grounded hundreds of flights across Europe causing travel chaos and costing the European airline industry billions of Euros.

Easy Access to Satellite Weather Data
Whatever the weather in Europe, EUMETSAT’s meteorological satellites will be observing it. The good news for researchers, climate modellers, and amateur meteorologists is that the data they produce are freely available for non-commercial or research purposes. You can even set up your own reception station.

Large X-class Flare Erupts on the Sun
On Jan. 27, 2012, a large X-class flare erupted from an active region near the solar west limb. X-class flares are the most powerful of all solar events. Seen here is an image of the flare captured by the X-ray telescope on Hinode. This image shows an emission from plasma heated to greater than eight million degrees during the energy release process of the flare. Image Credit: JAXA/Hinode
