Solar Activity Plot Page. CHARTS UPDATE DAILY  X-ray
FluxA daily average background X-ray flux in the 1 to 8 angstrom range. It is a midday minimum designed to reduce the effects of FLARES. Rank of a FLARE based on its X-ray energy output. Flares are classified by the order of magnitude of the peak burst intensity (I) measured at the earth in the 1 to 8 angstrom band as follows: (watts/sq. meter) Class B - I < 1.0E-06 Class C - 1.0E-06 <= I <= 1.0E-05 Class M - 1.0E-05 <= I <= 1.0E-04 Class X - I >= 1.0E-04 SEE FLARE INFORMATION IN THE NEXT CELL ----------------------------------------------------------------------------------------------  Satellite
Environment (combined)This is the combined image from all three of these charts. The SPOTS on the Sun are important, but for HAM RADIO operators, it is the spots in the Southern Hemosphere that mean the most to us. The FLARE is a weather indicator as it charges and propels the sun's particles and gasses out into space. With lack of FLARE activity the Earth will be cooler therefore ice caps will increase in size. FLARES often can increase changes in the JET STREAM which relates to CLIMATE CHAOS... FLARES can often wipe out the ham radio and shortwave bands almost immediately and it can take minutes to hours for the bands to recover. If the ham radio bands seem to go dead all of a sudden, it is always a good idea to check this chart to see if a large flare has occurred recently. ----------------------------------------------------------------------------------------------  MagnetometerChanges in the Magnetic pole activity based upon the sun's magnetic wind storms. These storms are present in the SPOTS and can be very severe in high FLARE active zones. ----------------------------------------------------------------------------------------------  Estimated
Kp IndexA 3-hourly planetary geomagnetic index of activity generated in Gottingen, Germany. The graph is based on the K INDEX monitored by 12 or 13 stations and the results distributed freely around the world. Within a GREEN bar, you can expect a soft HF condition with fair to good DX on 160-75-40 mtr. When the bar reaches YELLOW, you can expect better conditions for 30, 20 17 and 15 mtr bands. When the RED bar graph is included, most all HF bands will see a dramatic increase in activity. The bands above 20 thru 6 meters will be very active. However 160 and 75 will degrade with noise. ---------------------------------------------------------------------------------------------- CREDIT: This information provided by NRO - Nobeyama Radio Observatory |
