  • The product contains probabilistic forecasts of X-ray solar flare activity expected to occur within a 24 hour period following the forecast issue time. The forecast probabilities pertain to the full visible solar disk and/or discrete active regions on the Sun. The probabilities relate to flaring at each of two magnitude levels: 1. M-class or greater flares (peak flux in 1-8Å band exceeding 10^-5 W/m^2) 2. X-class or greater flares (peak flux in 1-8Å band exceeding 10^-4 W/m^2). The forecasts are generated by the Australian Bureau of Meteorology every six hours at 0000UT, 0600UT, 1200UT, 1800UT, by combining statistical models of solar flare activity with forecaster input. The forecast product is in XML format.
