Weekly Highlights and 27-Day Forecast

This document provides a look at the highlights of space weather events and the 27-day outlook, summarized from The Weekly. The Weekly contains all the information SWPC considers pertinent to it's forecast of solar activity. Users can use the data to assess their own needs and requirements, given the likely solar activity the space environment has experienced.

The contents of the Weekly have no copyright or other restrictions. Comments concerning the content or improvements to the Weekly are invited.

The Preliminary Report and Forecast of Solar Geophysical Data (referred to hereafter as the Weekly) is compiled and issued every Monday. This publication is produced in Boulder, Colorado, jointly by the National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center, formerly the Space Environment Center, and the Air Force Weather Agency (AFWA). It is a continuation of the weekly reports that began in 1951 and were issued by the High Altitude Observatory and NOAA and/or its predecessors. The current series began with serial number PRF 001 on 09 September 1975.

Additional information about the weekly and how to make use of it can be found in the User Guide.
