469 FXXX02 KWNP 070256 WEKFOR :Product: 27-day Space Weather Forecast :Issued: 2025 Jul 07 0230 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 07 July - 02 August 2025 Solar activity is expected to be at low levels from 07-11 July, with several regions expected to rotate off the disk and no major groups expected to return. After 12 July, several returning regions could prompt conditions to increase to moderate levels through 25 Jul, then be hit or miss for the remainder of the period as several regions rotate off the disk and others rotate on. No proton events are expected at geosynchronous orbit. The greater than 2 MeV electron flux at geosynchronous orbit is expected to be high levels from 20-29 Jul under recurrent CH HSS influence. Moderate levels are expected from 07-19 Jul and again from 30 Jul-02 Aug. Geomagnetic field activity is expected to be at G1-G2 (Minor-Moderate) storm levels early on 07 Jul as possible transient effects co-mingle with lingering CH HSS influence. Quiet to unsettled conditions are then expected to return from 08-21 Jul, with isolated active periods possible on 15-16 Jul, under positive polarity CH HSS influence. From 22-27 Jul, a shift to negative polarity CH HSS inluence is likely to bring unsettled to active conditions, with isolated periods of G1 (Minor) storm conditions on 23 Jul. Mostly quiet levels are then expected from 28-31 Jul before another negative polarity CH moves into a geoeffective position on 01 Aug, bringing in unsettled to active levels through 02 Aug.
