The pioneering space experiences will be the ultimate voyage to encounter new planets around distant stars. Theirs will be the journey into the extraordinary. On distant planets are incandescent storms big enough to swallow the earth. Bolts of lightning thousands of miles long. Raging infernos of toxic gas. Inconceivable violence and terrifying extremes. These are the planets from hell.

April 28 2012 CHANCE OF SOLAR FLARES TODAY HD
Sunspot AR1465 has developed a 'beta-gamma-delta' magnetic field that harbors energy for strong flares. NOAA forecasters estimate a 20% chance of M-class eruptions during the next 24 hours. Because the active region is located on the Earthside of the sun, any flares from AR1465 will likely be geoeffective.
Even without a strong eruption from AR1465, ionization waves are already rippling through Earth's upper atmosphere. Dave Gradwell of Birr, Ireland, recorded a series of sudden ionospheric disturbances (SIDs) on April 27th:
Low-level flares from several sunspot groups (especially 1465, 1466 and 1467) are strobing the atmosphere with ionizing radiation. Using a VLF receiver, Gradwell detected their effect on the propagation of radio signals transmitted from France. So far the disturbances have been relatively weak, but this could change if AR1465 unleashes a more potent eruption over the weekend. Solar flare alerts
