Observers: Rafael, PJ

S1S2E1E2W1W2 / POPs 551125

start with: beam 1 2 3 = S1 S2(REF) W1 / POPs 552

clear

UT 05:00 = 10pm local
lost time until now because S2 was lost and we had to find star manually on Vega...

OK seeing

05:50 target1 = hd142666
-5530 um / 2586um
only S1S2 fringe ... and even that one is low SNR ... like yesterday
S2 flux x1/2 low compared to other telescopes...

back at cal hd148211
cannot find the S2W2 fringe...
give up on this, should be doing mwc275 instead...

-5162um / 2050um
all fringes are there, but S1W1 and S2W1 are small...
hard to keep them tarcked...
