-- JohnHill - 15 Oct 2007 Hi Matt Coleman and Dave Sand are at the LBT. Olga is helping and it is great.

0110 UT -- Opening Dome. Having some trouble retracting. After a couple minutes the problem was fixed.

~0125 -- Took one round of g flats. Already quite dark, so we're going to try to focus on a standard field.

~0130 -- going to SA110 to focus. clearing active optics

0135 Took initial Vfastxtra. No good pupils found +3000 z5

0139 z11 +1000 Now images are triangular with hole in the middle.

0149 z8 +1000 Getting better

0153 z7 -200 ; z5 +1000 Not really much better

0156 z5 +2000 Maybe getting rounder

0159 z5 +2000 Olga thinks it is getting better

0202 z11 -200 The mirror is colder than ambient

0206 z4 -2000

0215 z10 +500 and then +500 again. Hill says triangular images mean the seeing is good. Can't wait!

0218 z4 +2000 pupil too big

0223 z5 -500

0226 z10 +500

0229 z8 +1000

0233 z7 -1000

0235 z9 +500

0239 z5 +500

0242 z9 -1000

0244 +500 z9 +500 z10

0248 Found Pupils!!!!!!!! applying corrections

0249 z10 +500

Many more iterations....

0314 SA110_4p_Vgr -- We believe it is photometric. AM~1.5. seeing is 1.6, but there is residual poor focus. help!!

0334 With poor seeing (and tough focusing) we decided to go to the Muzerolle program.

0340 Begin sdt_muzerolle_3_1 --- Ugh, guider says 2.5 arcsec seeing. First image -- Stars are nice and round, but seeing is ~2 arcsec. We will complete this OB and then probably move. I guess if Muzerolle could check this to see if the data is good enough for his purposes, I can check it off.

0408 -- Running Vfas on Ryan 15 deg field. Had to move dome.

0422 -- Ran 2 VFastextra's

0429 -- First Ryan OB. Guider says seeing is now ~1.5" First Ryan exposure has seeing of 1.1 arcsec.

0444 -- Moving to rbs1774_b_05; Schwope

0451 -- Beginning rbs1774_b_05 -- seeing is bouncing around between 1.0 and 2.0 arcsec. If Schwope can check the OB before it being check off...

0524 -- Returning to Ryan 15 deg field; running Vfastextra's

0538 -- Beginning Oct_15_deg_epoch2 -- Possibly guiding on a galaxy on first exposure. How can this be fixed? Second exposure has 1.2 arcsecond seeing.

0552 -- Moving to M31_H1B_16 -- Ran Vfast's

0604 -- Beginning M31_H1B_16

0622 -- Moving to M31_H1B_18 -- running Vfast

0631 -- Beginning M31_H1B_18 guider seeing is ~1.2"

0656 -- Moving to M31_H1B_20 -- running Vfast

~0710 -- Beginning M31_H1B_20

0728 -- Moving to Oct_15_deg_epoch3

0739 -- Beginning Oct_15_deg_epoch3

0754 -- Moving to StanekM33 -- running Vfast

0804 -- Starting Stanek M33 -- Guider failure?? This is weird, seeing was 1" and then guiding stopped. Stopped this OB

0808 -- after inspection of tec chips, it seems we are way out of focus. running Vfast...running very sluggish.

0811 -- after running lbcpfia, we get this error -- Error on TCSWavefront()

0817 -- trying StanekM33 again. First image is crap. Looks like there was a telescope wobble or something. guider is reporting ~1.0" seeing. keeping an eye on it.

0832 -- This is bad. The center of the field seems to be in focus, roughly 1". But, you go to chip 4 (towards M33, it looks like) and the image looks terrible. Possible field dependent distortion (from Olga)? Finishing OB, but then moving on.

0849 -- running vfastextra on M31_H1B_22 field.

Finished the 22 field. Seeing is good at ~1".

0918 -- Going to M31_H1B_24

0923 -- Starting OB; seeing is ~1.1-1.2 arcsec.

0948 -- Going to And_IX_BL. Seeing is ~1.0 arcsec. By 5th exposure, seeing is ~1.3-1.4

1037 -- Went to M81extrafoc.ob in prep for KochanekM81V

1047 -- Switched to KochanekM81V OB. Seeing is good 0.7-1.0 in guider. First image is subarcsecond. Best of night.

1054 -- Going to UmaII_2_B. During 3rd exposure seeing went to crap. 2.5+ arcsec.

1131 -- Starting UmaII_3_B. seeing seems to be ~1.0" again. Was last exposure a fluke or guiding on galaxy?

1158 -- Moving to SA98_rotm45_UsUBVgr -- Want to make sure to get standards. Night was probably photometric.

1223 -- Peaked outside. Getting light out. Heading to FF spot.

1228 -- SkyFlatR_5

1248 -- SkyflatRrot180_5 at 7 sec -- last image near saturation

1253 -- SkyFlatRrot270_5 at 1 sec

1258 -- We need to take biases. But then, good night.
