Grand Observations


Mary Beth Schwarz reports that since I've left, the mode shift at Grand continues. There have been several more false Vent overflow delays, and then yesterday (04 July) Grand had it's first known "boop" delay in several years. (A "boop" is when, during a Turban heavy overflow delay, Grand has boiling to up to several feet over its vent which does not result in an eruption. )Like the false Vent overflows, this usually results in several Turban interval delays.In this case, six. Fortunately, the delay took place early in the Grand interval, which kept that interval from being excessively long.
