Huge Dark Spot Shows Up on the Sun Disc

The peak of the magnetic activity of the Sun has been reached a couple of years ago, so large sunspot were not expected to develop by now, however the ones that appeared on early January are really huge, actually the largest in years: the central group, labelled as AR1944, spans for over 200,000 km, while the main dark nucleus standing right in the centre of the sun disc is some 40,000 km accross, that is more than 3 times the size of Earth !...

With the proper filters or specialized eclipse glasses this particular dark spot was even easy to glimpse without any optical aid, making it the first naked eye feature visible on the surface of the Sun since the transit of Venus on June 2012...

New Moon for a New Year

By a mere coincidence the New Moon occurred in the night from December 31st to January 1st, so the year and the Moon cycle began together. Of course this is of no relevance, except by providing nice views of the thin crescent phase in the first sunset of 2014.

As seen from our observing room, the Moon missed by very little the setting behind the domes of the Cerro Tololo Observatory located in front of us, but maybe that would have been too much asking...
