Looking at the diagram for this formation, we see a period of eight circles around the centre. However, the centres of the eight are reversed, suggesting day and night proceeding for four complete 24-hour days. The black lense-like figures on each side of the eight circles represent darkness at the beginning and ending of each of the circles. In other words, for four days, there will be less light from the sun reaching earth due to the dust and gas obscuring the sun’s rays, particularly enough to affect the actual times of dawn and dusk. It isn’t quite clear whether this applies to countries in addition to Germany, or if the comet is only B or also others.
