Yes, we can clearly see it on two verticals located south of LA. Looks
like the LR arrives there around 10:21+ UTC which matches with the Honshu
5.0. When filtered 0,002 - 0.08 the peak energy is at around 22sec and
peak amplitude is around 50nm/s, which is only a little over 5 counts for
us. The background peaks are around 2-3 counts. This is one of the
smallest we have seen, too, though I think that in the past we may have
seen a couple at about 90 degrees in the high 4's.
