  The Met Office Space Weather Operations Centre produces 24/7/365 space
weather guidance, alerts, and forecasts to a wide range of government and
commercial end users across the United Kingdom. Solar flare forecasts are one
of its products, which are issued multiple times a day in two forms; forecasts
for each active region on the solar disk over the next 24 hours, and full-disk
forecasts for the next four days. Here the forecasting process is described in
detail, as well as first verification of archived forecasts using methods
commonly used in operational weather prediction. Real-time verification
available for operational flare forecasting use is also described. The
influence of human forecasters is highlighted, with human-edited forecasts
outperforming original model results, and forecasting skill decreasing over
longer forecast lead times.
