John, First I assume you are referring to the Heavens-Above site? If so, for me, it's a good question. Several months ago I gad a similar experience. I assumed it to be caused by too much tequila on my part. I will try too reload flare predictions as the predicted time approaches and see when the "disappearance" occurs. This may take a few days. Surely such a sophisticated site should allow a simple person to come home from work, check for flare passes, and run outside, just barely catching the view.
