403 FXXX02 KWNP 131026 WEKFOR :Product: 27-day Space Weather Forecast :Issued: 2024 May 13 1017 UTC # Prepared by the US Dept. of Commerce, NOAA, Space Weather Prediction Center # Product description and SWPC contact on the Web # https://www.swpc.noaa.gov/content/subscription-services # # 27-day Space Weather Forecast # Forecast of Solar and Geomagnetic Activity 13 May - 08 June 2024 Solar activity is expected to remain at moderate to high levels through the forecast period. Region 3664 will rotate off the visible disk by 14-15 May, and another 10 regions will depart the visible disk between 16 and 23 May. This will lead to a relative lull in activity compared to the past week. However, a couple of regions rotating on will maintain the potential for at least moderate activity. Region 3663 is expected to return on the 23rd and Region 3664 on the 28th of May, with a significant increase in the threat of high activity. There is a chance for proton events at geosynchronous orbit, particularly with the return of Region 3664. This doesn't preclude the possiblity of an event in the days leading up to the 23rd, but the risk will increase with each day Region 3664 moves across the visible disk. The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at moderate levels throughout the period. Geomagnetic field activity is expected to be at minor storm levels to being the period, with a lingering chance of moderate to strong levels through the 14th. A relatively quiet period follows, interupted by coronal hole high speed stream activity between 23 May and 3 June.
