Huge solar flare – Alert for possible mid-latitude auroras in the next days

On 15 Feb 2011, active region 1158 let loose the largest flare since Dec. 2006 and the biggest flare so far in Solar Cycle 24.  Since the active region was facing Earth, there is a good chance that Earth will receive some effects from these events, with some possibility of mid-latitude aurora Feb. 16 – 18.

Kepler discovers its first rocky planet

NASA’s Kepler spacecraft has discovered Kepler-10b, its first confirmed rocky planet and the smallest transiting exoplanet discovered to date. Kepler-10b is only 1.4 times the size of Earth and has an average density of 8.8 grams per cubic centimeter, similar to that of an iron dumbbell.

The planet orbits its star in only 0.84 days and is not in the habitable zone, where liquid water could exist.

With still in the eyes the incredible show put on by the Sun and the Moon during the 4 Jan partial eclipse, I wanted to summarise (in chronological order) next eclipses (Solar and Lunar) that will be visible during this decade in Europe. 

And if you don’t want to miss totalities, mark these days on your agenda:  Continue reading

Partial solar eclipse – the “Crescent Sun”!

This morning Marco and I moved to a site close to Turin where the meteo forecast were not so bad (as in our city) to try to observe and photograph the partial solar eclipse. Unfortunately, when we arrived it was cloudy and foggy and so decided to go back home. Suddenly, as I was sadly driving on the motorway, close to the city of Alessandria, noticed a little break on the clouds from my rearview mirror: I stopped the car and, after a quick set up, we managed to capture the crescent Sun!
