According to the latest data from the NOAA Space Weather Prediction Center, geomagnetic conditions are expected to remain mostly quiet or moderately active through the end of this week. The greatest increase is expected on June 12, 2026, when the planetary Kp index may briefly rise to 4, but this is still below the threshold for a G1-level geomagnetic storm.
In its forecast for June 10–12, NOAA explicitly states that G1 storms or stronger events are not expected. On June 10 and 11, the geomagnetic field is rated as quiet to unsettled, and on June 12, a transition to unsettled to active is possible. This means that the background activity may become noticeably more intense, but without signs of a truly strong storm.
For the weekend, June 13–14, the operational 27-day forecast also shows no sharp deterioration: the highest expected Kp for both days is 2. At the same time, the latest NOAA forecast discussion mentions a possible lingering effect of a coronal mass ejection near Earth on June 14. This is more of a signal to keep an eye on updates than a reason to expect a strong storm right now.
So, as of June 10, the outlook for the rest of the week looks relatively calm: no major magnetic storms, but with a likely brief increase in geomagnetic activity on June 12. If you need the most cautious forecast, it’s worth checking NOAA updates closer to Sunday, June 14, when the assessment may be revised.
