Description: A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications.

  1. The dolphins seen at San Diego Coast: It is a sign of drastic and abrupt change of earth plate tectonic place, which it will trigger fenomenals and fatals changes in earth ecosystem-weather. The Dolhins, among many animals, are the best Natural-Radar-Detectors sensor. All this,input,and written in a definite(from zero to a stablished infinite) integral mathematical equation, has already been solved by me.
