Looking at the trends posted in LHO alog 36024, the problem with the ITMy oplev appears to be a failing laser diode.  Since LLO was down, it was decided to perform a swap of this laser with one I recently stabilized in the lab.  The motivation is so we have a before/after record of the ITMy pointing for the vent beginning next week; it was thought to be better to perform the swap now, versus during the vent (either due to preventive maintenance or laser failure) and this effecting the alignment reading of the oplev (in theory it shouldn't, but we all know that old saying about theory and practice...).  New laser SN is 120-2, old laser SN is 189-1.  As is usual, the laser will need a couple hours to come to thermal equilibrium with its new home, then I can assess it for glitchiness.  I will leave WP 6616 open until the laser is operating glitch-free.
