We noticed today that the horizontally pointing halo lidar (the Metek one, on top of MISS) is intermittently seeing a hard target at about 1500m out, like in this plot:
We talked some with Shane about it, and with the range, it seems like it's most likely hitting the trailer tower.
Looking back through previous screenshots, we've seen this happen at least as far back as 8/25. The bright line doesn't show up very well on the thumbnailed images, so it's possible it's been going on longer, we just haven't found an example of it yet.
Since the trailer tower is offset to the north of the array, does this mean the lidar isn't lined up with the array? Or is the beam wide enough we could be seeing it even if it's pointed at the array?
