Sunday: The full moon occurs today at 9:46 a.m. The moon will have set for this hour, but it will be full tonight. The full moon of December is known as the cold moon, of the cold nights that arrive during December. This is also a Super Moon, since it occurs at approximately the same time as when the moon is closest to Earth. Tonight, the moon will appear approximately 5 percent larger than normal.
Monday: This morning there is a bright flare of Iridium in the north. Iridium eruptions occur when Iridium communication satellites reflect sunlight from their solar panels to observers on Earth. The flare this morning occurs at 6:01 a.m., at 51 degrees above the northern horizon in an area without bright stars.
Tuesday: Over the next few days, Mercury and Saturn are close to each other low in the west-southwest. At 5:45 p.m., the pair is only a few degrees above the horizon and are separated by approximately 2 degrees. Tomorrow night they are a little closer and Saturn is the taller of the two. The binoculars will facilitate the detection of both planets through the brightness of the sunset.
Wednesday: It is easy to detect Jupiter and Mars this morning. Jupiter is the brightest of the two planets and is the brightest object in the southeast. Mars is located in the upper left of Jupiter and has its characteristic red color.
Thursday: Another Iridium flare occurs at 7:07 p.m. This time the flare can be seen at 27 degrees above the southern horizon and below the weak constellation Cetus, the sea monster.
Friday: This morning the gibbous moon is in the same area of the sky as the Regulus star. At 6 a.m., the pair is separated by about 12 degrees, with Regulus slightly towards the upper left part of the moon. Regulus marks the heart of the Lion, and for the ancient Persians was one of the four royal stars who ruled over the stars in the sky.
Saturday: At 7:30 pm, the Andromeda constellation is high in the west. Andromeda looks like the letter "V" that opens to the north. The apex of the "V" is the head of the princess and the other stars trace its outline. The second star on the left side is one of the stars on his waist. With the binoculars, look 4 degrees to the left of the star to find the Andromeda galaxy. The galaxy will appear as a faint patch of light.
