Thursday afternoon we had a brief but strong wind event--See first plot: 2 day's minute trends.  I had moved the roaming STS2 a week or more ago and now resides at position Roam9.  At the corner station the wind average touched on 20mph for maybe 90 minutes with a stable direction of about 170^o or ~from EndX toward the corner.  No non-wind seismic evident.

The second attachment shows the usual STS ASD comparisons between the Roaming HAM5 and the Detector used ITMY STSs, see 38184 for the Roam8 comparison and you can follow back from there.  Great news: for the X dof here at Roam9, the HAM5 STS shows several factors less floor tilting than ITMY starting at 30ishmHz; and, the Y dof is maybe no worse--is that band between 10 & 100mHz too much?

So bottom line Roam9 shows promise!
