R Aquarii and Gamma Ray Astronomy

In the Antarctic Ice corethere exist many nitrate ionconcentration spikes due to gamma ray. A part of the ice coreextracted from the Japanese Antarctic station named Dome Fuji,corresponding with 11th century, shows three set of spikes.The first two possibly coincide with SN1006 and SN1054.The third one is probably due to the symbiotic binary R Auarii's outbursts (1073 and 1074AD)that were recorded in the ancient Korean documents as a " guest star". Moreover,there exist several nitrate ionspikes corresponding with other centuries. Some of the spikes without any historical records are possibly due to the gamma-ray from invisible or missing SNe or other (classical novae or symbiotic star)outbursts.
