Sand and Coleman here. Beautiful sunset. Candidate Photometric night. Good way to start the last night of SDT EVER.

0110 -- Taking 5 bias frames as dome opens to prepare for sky flats.

0123 -- Taking a SkyFlatG_5

0127 -- SkyFlatG_5 scaled by 15.

0133 -- SkyFlatGrot90_5 -- scaled by 30

0140 -- Moving to SA110_4p_Vgr

0142 -- Running Vfastextra

0228 -- After many Vfastextra's, we're going to run the SA110_4p_Vgr OB.

0241 -- Moving to rbs1774_b_10. Talked to Hill in the mean time. He gave the TO Erin some kung fu knowledge about possibly helping out with the focus.

0309 -- On generator power.

Everyone is scurrying around to fix stuff. I"m going to make dinner.

This last is looking good. Lets get started!

0337 -- Starting Schwope OB rbs1774_b_10

Seeing is 3 arcsec. Forget this!!!!!

Stopping OB and going to Ryan fields..

0349 -- Moved to Oct_0_deg_epoch_1 -- AM is 1.77, but we ain't got nothing else to do.

0350 -- Running Vfastextra

0354 -- Oct_0_deg_epoch_1 -- Lost guiding after a minute or so, (at which point it was saying the seeing was ~6 arcsec) even with 32 sec exposures. Went outside. No clouds. Can the seeing really be that bad?

First image has 4 arcsec seeing. Not even Ryan can use this!!!!

0414 -- after more Vfastextra, we are repeating Oct_0_deg_epoch_1 and will continue to do so until seeing gets to be ~3 arcsec.

0426 -- seeing is still 3.5"

0432 -- Another Oct_0_deg_epoch_1

0501 -- Seeing still 3.5 arcseconds. New plan. Cycle through the Ryan fields, giving them a 1.5 times the exposure time. Hopefully they will be useful.

0502 -- Moving to Oct_10_deg_epoch_1

0502 -- Vfastextra

0522 -- Moving to Oct_15_deg_epoch_1

Vfastextra 0534 -- Beginning Oct_15_deg_epoch_1 seeing is 4+ arcsec.

0552 -- Moving to Oct_0_deg_epoch_2

Vfastextra

0559 -- Beginning OB

0611 -- Moving to Oct_10_deg_epoch_2

Vfastextra

0615 -- Beginning OB

0626 -- Watch out people. Seeing is now 2 arcsec.

0633 -- Doing Oct_15_deg_epoch_2

First image still has 2 arcsec seeing.

0646 -- Second image looks double, like the telescope stopped tracking. I'm going to retake the OB. not much else to do..

Seeing still 2.5 arcsec. 0658 -- Moving to Oct_0_deg_epoch_3

0702 -- Vfastextra

0705 -- Beginning OB

First image has ~1.8" seeing. we're getting there...

Seeing 2" in second image.

0721 -- Beginning Oct_10_deg_epoch3 OB.

First image is 1.6"! Ok, if this holds for second image, we're moving to new targets.

0736 -- Alright, we figure we are close enough to ~1.5 arcsec and it is the last night of SDT. We are moving to Clementini fields.

0743 Starting M31_S2B_27

The first image had 1.8" seeing. Crap. What we'll do is repeat the OB, doubling the exposure time. Hopefully this will be usable then.

image 2 -- 1.9"

0803 -- repeating the OB.

Seeing is now firmly 2+ arcseconds.

Moving back to Ryan. Wishful thinking that things were getting better

0822 -- Moving to Oct_5_deg_epoch1

0836 -- First image has 2" seeing

0842 -- Moving to Oct_20_deg_epoch_1

0848 -- Beginning Oct_20_deg_epoch_1 OB.

0903 -- Moving to Oct_15_deg_epoch_3

0904 -- Vfastextra

0915 -- Seeing still 2+ arcsec

0923 -- Oct_5_deg_epoch_2

0925 -- Vfastextra

0929 -- Beginning OB Second image had seeing of 1.5. Moving to Clementini field. Hopefully it holds.

0945 -- Moving to M31_S2B_29

0947 -- Vfastextra

0950 -- Beginning M31_S2B_29 First image is 1.8" seeing. Blech. wrong move. I will run the OB twice and hopefully it will be useful.

1008 -- Vfastextra

1011 -- Second round of M31_S2B_29 First image is 1.7" Seeing is still bad.

1032 -- Moving to And_IX_VL

1033 -- Vfastextra

Since seeing is bad, I will scale the images by 2.0 1039 -- We are having trouble with the repository.

restarted the lbc archive machines

1048 -- rerunning Vfastextra

1051 -- And_IX_VL running. seeing sucks. we don't have a ton else to do.

1131 -- Going to KochanekM81BV -- Hopefully 2"+ can be useful...

1133 -- running M81 focus

1140 -- Running OB. Seeing has improved a bit. between 1.5 and 2.0 arcsec.

1151 -- Seeing is getting worse for the B images -- 2-3 arcsec. sorry, not even this is working...

1157 -- Moving to SA98_rotm45_UsUBVGR

1201 -- Vfastextra

1205 -- Beginning SA98_rotm45_UsUBVGR

1222 -- Moving to FF spot.

1223 -- SkyFlatTestR

30 sec.

1234 -- SkyFlatR_5 30sec

1242 -- SkyFlatRrot270_5

1249 -- SkyFlatRrot90_5

1254 -- SkyFlatRrot180_5

Good bye SDT!
