[Geysers] Unusual Penta and Oblong and misc. July 31 - 3 August 2010

[Mary Beth Schwarz]

     On 31 July Barbara Lasseter called Penta at 1123ie.  That seemed odd
since Sawmill was 0931ie and ended between 1021 and 1030.  Spasmodic was in
early overflow and the Sawmill group was rising.  Sawmill's water level was
high but not overflowing and Tardy was high but not ie nor did it erupt
during the approximately 1 hour eruption of Penta.  Spasmodic dropped below
overflow and the group was on a drain.  At 1320 Sawmill started and erupted
about 30 seconds.

     On 2 August while waiting for Grand we saw Oblong start at 1025ns.  At
about 1030-1031 the bursts were not only above the dead tree as seen from
Grand but also to the top of the trees in the distance, something that we
had not observed before.  The next eruption of Oblong at 1836 seen by
Heinrich Koenig was small.

     Grand has had more Vent delays in the last few weeks.  Today 3 August
Grand erupted with the 3rd Turban after the Vent delay at 1437(V3/T2*C) with
an interval of 10h 2m but several have been with the 5th Turban after the
Vent delay (Vent overflows and Grand is high and has waves and it appears
that Grand will erupt and then Grand drops and there is a delay).
Everything seemed ready today with fine waves at 1339 but then Grand's pool
dropped.

     Beehive's Indicator on 2 August had a short lead time at 1311ns with
Beehive at 1318 (d=5m 16s).  Today 3 August Beehive's Indicator was at 1114
and Beehive at 1137.
