December 14 / Geminids

The Geminids are a highly active meteor shower that occurs from December 04-17. His best moment this year will be on the night of December 14-15. An estimated 120 meteors per hour are expected. This meteor shower is produced by debris from the asteroid 3200 Phaethon. It is worth mentioning that, to be able to observe this type of show, the ideal is to get away from the city and light pollution. Another very important factor to take into account is that the moon will be in a phase between 90% and 97%, which will add light, this will cause fewer stars to be seen than expected.


December 21 / Winter Solstice

When the southern point of the Earth's axis points more directly to the Sun, the northern hemisphere experiences the longest night and the shortest day of the year, which is known as the winter solstice and will happen at dawn on December 21 giving it start to the fourth season of the year.


December 22 / Ursidas

This meteor shower is visible from both hemispheres, although it is less intense in the southern hemisphere, between December 17 and 26. The maximum activity of the Ursids is expected for the night of December 22 to 23 and due to the proximity of the new moon a dark sky is guaranteed for much of the night. 10-15 meteors per hour are expected. To be able to observe this type of show, the ideal is to get away from the city and the light pollution.


December 26 / Annular Solar Eclipse

Annular eclipses occur when the moon is at its peak and its angular diameter is smaller than the solar one. In such a way that a luminous ring is visible around the lunar disk. This phenomenon occurs once every two years. This astronomical event will occur on December 26 at 05:18 UTC. It will not be visible in Mexico.
