Effective February 18, 2022, the NWS will discontinue the Legacy Wang Sheeley Arge Website

issued by the Space Weather Prediction Center. This webpage provided graphics of the predicted solar wind speed and interplanetary magnetic field polarity at Earth. There were six comments received, four of which advocated to continue the website for research purposes. Two comments acknowledged the retirement of the website with one request for the website to be archived for historical purposes. A version of these products is expected to run on the NWS Weather and Climate Operational Supercomputer System (WCOSS) as a part of the WSAEnlil model system. SWPC has no set time frame for when these products will be available from the WCOSS version of WSA but it is not expected before the end of 2023. Users can access products from the WCOSS version of WSA at this website: https://www.swpc.noaa.gov/products/wsa-enlil-solar-wind-prediction If there are any questions, please contact:
