Ready to observe the Wonders of the Sky in December?

Last appointment of the year, let’s discover together what the sky in December holds!

Also this month Venus, Jupiter and Saturn will be undisputed protagonists, with an alignment visible between 15 and 17 December. You can watch them from sunset, looking southwest.

If, however, you have unexpressed desires in your drawer, two meteoric swarms will give you the opportunity to express the last wishes of 2021. It’s about the Geminids and the Ursids.

Let’s start from these last ones, the #Ursids, observable looking towards the pole star, in the constellation of the Ursa Minor, obviously to the north. The Ursids, unfortunately, will be a little more difficult to observe since they will reach the peak between 20 and 22 December, shortly after the full moon. The Moon, high and full in the sky all night, will disturb the observation. 

Similar problem but bypassable with the #Geminids, which will peak in the nights between 12 and 14 December and will be visible looking towards the constellation of Gemini, to the north, northwest of Orion. To avoid the disturbance caused by the moonlight, try in the late evening, starting at midnight, when the Moon is about to set 

Finally, if you are looking forward to the days being extended again, know that you need to be patient a little longer. December 21, in fact, will be the shortest day of the year with just 9 hours and 6 minutes of light (at the latitude of Rome). It is the winter solstice, when the sun will reach its maximum negative declination, but from that moment on the days will continue to grow longer.
