Because of high seismic noise due to several big earthquakes, a swarm of earthquakes, and a typhoon (Fig.4), the IFO lock was almost not realized last night. Therefore, the IM temps of ITMY and ETMX decreased significantly. I kept adjusting the current of the heaters for them. The attached values are the original settings before the adjustments. 

Fig.1 and 2 show the original settings for ITMY and ETMX. I increased by 2 Volts for each for several hours. After that, I reduced by 1 volt for each. So the present voltages are larger than 1 volt for each. 

I will recover the original setting values after confirming the stable, continuous lock.
