Jewel Geyser Update 1990

Ralph C. and Brenda K. Taylor

ABSTRACT: This report describes the authors' observations of Jewel Geyser in August, 1990 and May, 1991. Ninety five closed intervals over a total of twelve hours in 1990 and one hour in May, 1991 are included in the data. A mathematical model relating the ob- served number of bursts in an eruption to the subsequent interval described in a previous paper is updated with 1990 observations. The interval to the next eruption is predicted within 2 minutes by adding 4m25s plus lm5s for each observed burst in an eruption.
