[Geysers] Fan and Mortar 13 and 19 September 2011

[Graham Meech]

You already heard that Fan and Mortar erupted on the 13th and I have details
below.  Jake Young also reported another eruption seen by Dave Leeking at
1921ie on the 19th.

 

Having erupted at 0039 on the 9th, 24 hour a day F&M watch started on the
11th.  There were events as follows:

9/11  1044, 1618, 1734

9/12 0031, 0436, 1345, 2150

9/13 1300 then observations were limited once Giantess started at 1332.  I
went down later after dark and events proceeded as follows:

 

2250 Main Vent splashing in progress

2300 River on with Main still splashing

River may have paused but it was hard to tell with the steam and wind
direction in the dark

2316 River on strong

2318 Gold on

2327 Angle ie and water levels looked good

2335 LOCK

Like in the previous two eruptions Upper Mortar splashed up and died down
during the lock

2339 FAN AND MORTAR - Upper Mortar started the eruption followed by Main and
East together, duration 35 minutes.

Upper Mortar was strong, erupting continuously water and steam for 7 minutes
before going into the cyclic steam bursts.

 

F&M watch started up again on the 16th with an event at 1641 but no
overnight observations that night due to rain.  On 9/17 the first events
seen went like this:



0614 Main Vent splashing in progress

0618 River on with Main vent still splashing

0625 River off - a pause and Main still splashing

0633 River on and Main still splashing

0643 Gold on

0644 Angle on

0655 LOCK - Yeah

No splashes from Upper Mortar this time and no F&M

0705 UNLOCK - Booo

0719 River off

 

The next event was not until 1849 with Main vent splashing and 3 River
pauses.  No overnight watch again on the 17th and the next event observed
was at 0850 on the 18th just before I departed.

 

Here is the list of the last 21 reported eruptions and intervals from
www.geysertimes.org .  The ones with a question mark are where we are not
certain of the actual eruption times.
