AB: Previous studies have suggested that large solar proton events are followed several weeks later by nitrate spikes in ice samples. In an attempt to validate these initial results we have examined ice cores obtained from Summit, Greenland. To facilitate analysis of large sections of ice cores we have established a continuous flow analysis (CFA) system which allows for sub-yearly resultion of the nitrates. We present here our first results and compare with known solar events. Ultimately, such detailed analysis will allow us to probe historical solar events.
