1. In the mid-high latitudes of the Northern Hemisphere, there are three constellations all year round: the Great Bear Constellation, the Little Bear Constellation, and the Empress Constellation. At mid-latitudes in the northern hemisphere, around 2100 in early September, there are 3 constellations near the zenith: Lyra (which includes Vega), Cygnus, and Aquila (of which there are Altair). 2. The outer structure of the sun is divided into three layers from the inside to the outside: the photosphere (which has the “sunspot” phenomenon); the chromosphere (which has solar corona and flare); the solar corona (the solar activity is the “solar wind”) ). 3. The impact of solar activity on the earth is 3:1. When blackspots and flares increase, they emit strong shots.
