ACTIVITY LOG:

16:20  Robert out to LVEA to install a shaker.

17:30  Spent some time on the phone with Kiwamu getting this M2 to M1 SR3 offloading issue handled. Then another 3.9µcron from a 6.4mag in Indonesia. It’s going to be a bumpy day.

19:21  Looks like a good time to try and make something happen. EQ bands are back down in the .1µ region

20:15 after much struggling with alignment, Kiwamu is on site and showed me how close I was and how to overcome my impasse. Alignment commences. EQ bands now below .1µ. Sudarshan is also on site.
