The Sun experienced its first major flare in two months.
Data is coming in about a major solar event. At 3:19 UT, a flare of level X1.4 (the highest intensity) occurred—the first since February 4, 2026, or nearly two months. This is the second significant solar event in the last two days, following the plasma ejection that missed Earth, recorded on Saturday, March 28. Both cases involved the same active region.
The newly ejected plasma cloud is already visible in images coming from space. These images indicate that the bulk of the material is moving sideways. However, the offset—the deviation of the cloud's direction from Earth—is approximately 40°—an angle not entirely "safe," and the outer portions of the gas cloud could strike Earth.
As before (and now even more so), the event is inevitably correlated with the launch of NASA's lunar lander scheduled for April 1 (1:24 Moscow time, April 2, 2026). We'll soon find out how serious the agency considers the risks associated with this event and whether it will take them into account. If the edge of the cloud approaches Earth, it will do so between April 1 and 2. NOAA previously reported that it has been tasked with informing NASA about the possibility of solar radiation storms around the dates of the Artemis 2 mission to assess the risks to life and technology. The final decision, however, will ultimately be made by the agency, taking all factors into account.
