Jänis attacks!

Last week we made a service visit to KAIRA. There were four LBA aerials still down from the blizzard of 2014 and these needed fixing. However, on arrival at the site, we noted that there were some other LBA aerials down.


We hadn't noticed this in the data, so it must have been recent. And inspection of the field indicated that the nylon lines had been cut on multiple LBA aerials, which is what had caused them to fall.

We believe that the cause of this is a jänis (Wikipedia). These creatures like to gnaw on things and it looks like the LBA array was the target. Knowing our luck, it was probably the cute jänis we saw a while back.

What's worse, on the second day, we found yet more LBA aerials down. The jänis had struck again! (This led to much silliness on twitter.)

In total, some 10 LBAs were downed over two days (26-27 Aug 2014). More repair work for us then.
