Space weather is stabilizing

The rather strong solar activity observed on April 4-5 (more than 30 flares occurred over two days, including four M-level events) has concluded without significant consequences. Despite the source of the explosions being located directly at the center of the Sun, none of the flares was accompanied by an ejection of matter, which would have flown directly toward Earth, and all the energy was therefore wasted. Currently, the period of activity is clearly over—the flare graph is drawing something close to a straight line. Furthermore, the active centers have largely collapsed and have also moved away from the Sun-Earth axis. If this situation is applied to a lunar mission (to which everything is now inevitably applied), then there are no visible risks for the remaining four days of the mission. If this is the case, then it must be acknowledged that the timing of the mission was exceptionally fortunate. Not a single plasma ejection toward Earth occurred during this period.

Geomagnetic activity is slightly elevated, due to slightly higher-than-normal solar wind speeds (around 500 km/s versus the usual 300-400 km/s), but it still remains in the green zone. Wind speeds have been declining in recent hours, and geomagnetic indices are also falling. Forecasts are also green.

Visually, it looks like another lull after another surge. A typical pattern for the first half of this year.
