After locking the Xarm (we turned on the opLev damping, and slowed down the gain ramping in the guardian for the ALS COMM ). We aligned the IR to the X arm using IM4 and PR2.  Then we tweaked to BS alignment, and saw flashes of up to 350 counts on ASC_Y_TR_A_SUM.

We went out to the Y end to try to aling the beam onto the camera and LSC PD, but we didn't see the beam while the cavity was flashing and we notied that we still need power to the analog camera on the table. 

We came back to the corner and looked at the separation of the green beams on ISCT1; right before the prism they are separated by 9 mm. They were well placed on the prism as we found them. 

We currently have both the X and Y transmitted beams on the ISCT1 camera, and have marked both of their current positions on the monitor in the control room.  Tomorow we can use this as a reference for the BS alignment.
