Space Weather Prediction Center (SWPC)
27-day Space Weather Forecasts
Solar-Cycle Progression and Predictions
This directory contains solar activity summaries and predictions for
both 27-day and Solar Cycle time ranges.
Via Anonymous FTP: ftp.swpc.noaa.gov cd to /pub/weekly/
Via the Web: http://www.swpc.noaa.gov/ftpmenu/weekly.html
This is the same information published in the Space Weather Prediction
Center "Weekly" publication - Preliminary Report of Solar and
Geophysical Data, however, it is formatted for direct access and use.
The ascii text files have a fixed format for machine readability and
the images are in GIF format.
The actual "Weekly" publications and the User Guide, in adobe PDF
format, are on-line at http://www.swpc.noaa.gov/weekly/
Older publications, since 1997, are in the SWPC Warehouse.
http://www.swpc.noaa.gov/ftpmenu/warehouse.html
Descriptions of both the 27-day products and the Solar Cycle
products are available in the directory.
UPDATE SCHEDULE
The "Highlights and Forecast" and "27-Day Outlook" are issued
every Tuesday, usually by 2230UT.
The Solar Cycle products are updated once a month and are put
on-line the first Tuesday after the new data arrives. The latest
values are usually available on the 3rd of every month.
An email notification when the Weekly is issued is available
through the Product Subscription Service https://pss.swpc.noaa.gov/

================ Solar Cycle 24 Predictions =================
November 6, 2007
The initial ISES Solar Cycle 24 Prediction was released in April,
2007. The panel charged with determining the prediction was unable
to agree on a single solution and have so far provided two
predictions. Those two predictions are available here, along with
an average of the two predictions. The average is currently being
used as the official prediction. The ISES panel does not consider
this to be an adequate solution. To mitigate this, the lower and
upper bounds used with the average cover the range of the two
predictions issued by the panel. When the panel converges on a
single prediction, the files here will be updated to reflect the
new prediction. The two predictions issued by the panel can be
accessed in the files named Predict_low.txt and Predict_high.txt.
