813 FXXX12 KWNP 290031 DAYDIS :Product: Forecast Discussion :Issued: 2024 Jun 29 0030 UTC # Prepared by the US Dept. of Commerce, NOAA, Space Weather Prediction Center # Product description and SWPC contact on the Web # http://www.swpc.noaa.gov/wwire.html # # Forecast Discussion # Solar Activity .24 hr Summary... Solar activity was low with C-class flare activity observed from several regions. Slight growth was observed in Regions 3728 (S27E17, Dso/beta) and 3729 (S04E42, Eao/beta), while the remaining regions were stable or in decay. A new, unnumbered spot rotated into view near N08 on the E limb and produced multiple C-flares. A faint partial-halo CME, first seen in LASCO C2 imagery at 28/0024 UTC and thought to have originated from the active region cluster in the SE, is expected to be Earth-directed with a likely arrival on 03-04 Jun. .Forecast... Solar activity is expected to be low with a chance for M-class flares (R1-R2/Minor-Moderate) over 29 Jun - 01 Jul. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux was at normal to moderate levels and the greater than 10 MeV proton flux was at background levels. .Forecast... The greater than 2 MeV electron flux is expected to be at normal to moderate levels over 29 Jun - 01 Jul. The greater than 10 MeV proton flux is expected to be at background levels through 01 Jul. Solar Wind .24 hr Summary... Solar wind parameters became further enhanced due to the passage of a CME. An IP shock was observed in solar wind data at 28/0912 UTC, after which total field reached a peak of 30 nT, Bz briefly reached -24 nT, and solar wind speeds increased from 300 km/s to a peak of 493 km/s. .Forecast... CME-enhanced solar wind conditions are expected to continue into 29 Jun, with nominal levels likely to return on 30 Jun. An additional solar wind enhancement is likely on 01 Jul due to the anticipated arrival of CMEs from 26-27 Jun. Geospace .24 hr Summary... Geomagnetic field activity reached G4 (Severe) storm levels following the arrival of the 24 Jun CME. .Forecast... Periods of G1 (Minor) storming are likely to continue into 29 Jun due to residual enhancements following the passage of the 24 Jun CME. Quiet and unsettled conditions are expected on 30 Jun. Periods of active conditions are expected on 01 Jul due to the anticipated arrival of CMEs from 26-27 Jun.
