In the Photos of the Readers of La Vanguardia we can see the moon at 8% visible this morning with temperatures of 5 degrees below zero in Campdevànol, in the Ripollès region.
The effect of frost is noticeable, for example, on the windshields and bodywork of cars parked outdoors. It is a meteorological phenomenon that consists of a drop in ambient temperature to levels below the freezing point of water and causes the water or vapor in the air to freeze, depositing it in the form of ice on surfaces, such as on vehicle windows.
The extreme case of frost is the black frost, which is when a frost occurs with greater pressure and even causes the plants to be completely destroyed.
Since last January 4, starting at 4:30 a.m., we entered the waning lunar phase that is now approaching the new moon, which will occur on January 11, starting at 12:57 p.m., according to the calendar. .
In fact, the old moon is the last appearance of the moon in the sky two days before the new moon occurs. It rises in the east, shortly before dawn, just above the twilight of the aurora or dawn, has its zenith three hours before noon and sets in mid-afternoon.
In the northern hemisphere, the left side appears illuminated, as seen in the photographs, while in the southern hemisphere it is the right side that appears illuminated. It has the appearance of a scythe. It is one of the most famous images of the moon.
