Data for solar data and conditions from NOAA SWPC, solar flux fromĪnd world map/globes/solar system from Fourmilab (credit given).Data for Solar Flare Probability is from University of Bradford (used with permission).

Data for VHF Conditions is from DXrobot - Gouda, Make More Miles on VHF, and Andy (G7IZU) (all used with permission).The only sure-fire way to determine if the bands are open is to fire up that HF rig and get on the air! Of course, actual conditions at your location depend on a lot ofĪdditional items. HF Propagation predictions are just that, predictions calculated using the available data.World sunlight maps and globes, moon view globe, graphs and plots, and selectable current solar system planet locations. HF Conditions, VHF Conditions, EME degradation, selectable and fixed MUF, selectable K index (impacts conditions), signal noise and geomagnetic conditions, current secletable solar images, Solar banners are available in 19 different configurations (see below), with variations of solar indicies and measurements,.

Solar Radiation Outside the Earth's Atmosphere.

Therefore, the solar radiation intensity, H 0 in (W/m 2), incident on an object is: Where D is the distance of the object from the sun. The surface area over which the power from the sun falls will be 4πD 2. The total solar radiation emitted by the sun is given by σT 4 multiplied by the surface area of the sun (4πR 2 sun) where R sun is the radius of the sun. The solar irradiance on an object some distance D from the sun is found by dividing the total power emitted from the sun by the surface area over which the sunlight falls. However, at some distance from the sun, the total power from the sun is now spread out over a much larger surface area and therefore the solar irradiance on an object in space decreases as the object moves further away from the sun. At the sun's surface, the power density is that of a blackbody at about 6000K and the total power from the sun is this value multiplied by the sun's surface area. The solar irradiance (H 0 in W/m 2) is the power density incident on an object due to illumination from the sun. Only a fraction of the total power emitted by the sun impinges on an object in space which is some distance from the sun.
