We replaced the laser for the ETMy optical lever laser that had overheated last week (see alog 17986). Realignment was not necessary as the optical lever had maintained alignment. New laser SN is 193.

Actually, that Oplev stopped working 2 plus weeks ago around the 10th. Attached is a 20 day trend showing it gasping on the 10th.
