The background level Is 460 to 470 mv. Significant deviations are + or - 10% or less than 410 mv and greater than 510 mv. A sharp Itncrease that lasts for a few tens of minutes to hours is a Ground Leve! Event that Is caused by relativistic particles associated with solar flares. A sig- nificant decrease that lasts for several hours to several days Is a Forbush Decrease. This decrease is the scattering of background cosmic rays due to plasma density enhancements and associated magnetic field enhancements In the near earth solar wind. These enhancements may or may not be solar flare related. 40 Approved For Release 2000 PAC LA/SSIFIED 788R001800160001-6
