Note:09/23/1979 Caught the Whirligigs in dual eruptions this morning. First time I’ve seen this occur. Big Whirligig started with a five minute lead, the Little Whirligig joined in at 1057. Little Whirligig was weak in the beginning and continuous. Then became more powerful as Big Whirligig grew to the strongest activity I have seen. Big quit and Little quickly followed suit, the whole show ending at 1102.
