next we will move 503 Hz to 553 Hz because 503 Hz falls right in the hrec big peak (WI magnet)
reason is that we have increased distance from SDB2 ...

coil in the SDB1 N-W corner (close to EQB1) axis EW
07:14:52 UTC to 07:46:08
sweep 1800s 5V from 10 to 1000 Hz
lines 
from 07:46:08 to 07:58:00

coil axis NS
sweep 1800s 5V from 10 to 1000 Hz
from 08:01:48 to 08:32:55

coil axis VERT
sweep 1800s 5V from 10 to 1000 Hz
from 8:35:52 to 9:06:27

moved to TCS room
ENV_TCS_MAG_COIL_CURR_MON

-----IMPORTANT NOTE: we inserted the wron calibration: 10000 instead of 10, (!!!) 
remember to scale by 1000 during analisys


NI tower
small coil at NI MAG position, 

we unlocked while positioning the coil !!!

r10:19 UTC - ITF locked
quiet, good sensitivity
10:28:00 to 10:34

coil axis EW
sweep 1800s 5V from 10 to 1000 Hz
10:34:08 to  11:09:28

coil axis NS
11:16:37 to 11:54:07
sweep 1800s 5V from 10 to 1000 Hz

coil axis VERT
sweep 600s 5V from 8 to 330 Hz
11:59:15 to 12:20:27
unlock at 12:06:30 (earthquake?) when the sweep was around 150Hz (that is enough for us, so we move to WI)

WI tower

note: severat glitches in DARM maily around 15Hz.... seems not related to us
coil axis EW
sweep 1800s 5V from 10 to 1000 Hz
13:23:08
13:48:41 (we stop the sweep at about 850Hz to gain time, because after 150Hz we see nothing in Hrec)

coil axis NS
sweep 8 Hz, 330 Hz, 5V, 600s
13:57:36 to 14:07:57

coil axis VERT
sweep 8 Hz, 330 Hz, 5V, 600s
14:09:22 to 14:20:30

BS tower
coli axis EW
unlock because of Earthquake

The shift ends here. we leave the equipment in TCS room and small coil at BS.
