Two anomalously large, for a minimum of solar activity, a group of sunspots on the solar disk AR 2673-74. The area of the group of spots AR 2673 is equal to 0130 millionth of the area of the solar hemisphere or 0.754 S of the Earth (~ 384 million km2), the area of the group of spots AR 2674 is equal to 0930 millionth of the area of the solar hemisphere or 5,394 S of the Earth (~2 billion 750 million km2) .
The last group of spots has a beta-gamma magnetic field capable of generating X-ray flares of class M. The spots can be seen with a camera if there are thin layered clouds in the sky or with a telescope with a filter. At this point in time, the spots remain in a calm state.
S spots = 0.0058 * millionth part S of the solar hemisphere.
For the Earth: S = S spots * 510 million km2.
