if you are interesting in the DX conditions or bands propagations seriously then it is really important to know what's up in space in general...
GEOMAGNETIC STORM WARNING: NOAA forecasters estimate a 65% chance of geomagnetic storms on Aug 2nd when a CME is expected to strike Earth's magnetic field. A solar wind stream following close on the heels of the CME could boost storm levels to G2 (moderately strong). High latitude sky watchers should be alert for auroras.
Scientists classify solar flares according to their x-ray brightness in the wavelength range 1 to 8 Angstroms. There are 3 categories: X-class flares are big; they are major events that can trigger planet-wide radio blackouts and long-lasting radiation storms. M-class flares are medium-sized; they can cause brief radio blackouts that affect Earth's polar regions. Minor radiation storms sometimes follow an M-class flare. Compared to X- and M-class events, C-class flares are small with few noticeable consequences here on Earth.
