Pressure Pool cycling every 10 minutes, often overtopping it's rim and beautiful blue. Central vents weakly erupting most cycles, heavy steam or splashing in Grotto increasing with each cycle. Between 1500 and the eruption GF overflowed during high pressure pools, but never boiled in this time period. |

I believe Grotto is still i.e. from yesterday’s eruption
Marathon Pool down
Bijou off
Still i.e. when I left area at 12:30
The John’s formula for next eruption is:
I=1.7D+190 minutes
Last year I had a 24hr eruption, the next eruption began 2 hrs before the formula predicted |
