STATE of H1: Observing at 122Mpc
OUTGOING OPERATOR: Niko
CURRENT ENVIRONMENT:
SEI_CONF state: WINDY
Wind: 13mph Gusts, 10mph 5min avg
Primary useism: 0.04 μm/s
Secondary useism: 0.45 μm/s
Winds have died down over the last hour. Microseism is around/just below the 90th percentile.
QUICK SUMMARY:
H1's been locked 22.5+hrs.
There's no road access to MX on X1. And X2 to EX probably looks worse! Sorry, Chris & Tyler (seems like the #Tumlbegeddon tumbleweeds have finally been freed up from SR 240 and taken residence on our X-arm road! (see Jeff B's photos).
And now that we are 24hrs into our better sensitivity-H1, it's looking like whenever we get sustained winds around the 20mph range, we'll see that in our range. (but should also note we have the fairly high microseism, too). So just hope for less wind!
Sorry to ignore Y-arm, but it appears to be much better with no real change from Wed. It's dark now, but from what I can see, you can drive down most of Y1 to MY. Then immediately after MY there's a multi-car length tumbleweed pile blocking the road (this pile looks a like it's grown a little since Wed). Then looking from EY's camera in the dark, I see fairly clear road access on Y2 (on Wed there were two more multi-length tumbleweed piles).
Attached is a sunset photo I took from the roof. If one zooms in, one might see a few tumbleweed piles on Y1, but otherwise it's fairly clear.
Summary: Y-arm has a couple of blockages, which would require a little bit of time, but X-arm is almost entirely blocked the length of the 4km & is worse than it looked on Wed!
