The sun was empty (without spots) for 15 consecutive days. In order to find a similar section of the pure Sun in the history of observations, we must return by April 2010, when the Sun came out of a deep minimum.
Currently, the absence of spots foreshadows a new solar minimum, which is expected in 2019-2020. Until then, sunspots that can produce strong flashes should not appear. But the cosmic weather continues and becomes interesting. The solar minimum brings additional cosmic rays, pink auroras and much more. During March 22-23, a new stream of solar wind coming from the coronal hole will arrive to Earth. Auroras are expected.
