I thank Inez for her observations of Morning Mist -- which fit my own and other historic observations -- but none of this answers the question just posed: does Dick Powell's data show a series of distinct, individual eruptions or just episodes within one (ordinary, per history) hours-long eruption? I can add either way, how long did the eruptive activity last? Thanks Scott Bryan -------------- next part -------------- An HTML attachment was scrubbed...
