Observers: Jack Neustadt, Suk Sien Tie
TO: Steve Allanson
SA: Olga Kuhn

Moon phase: 

Summary: Mostly cloudy for the first half of the night, hopefully some usable data were taken. 
	 Thin clouds/clear for the rest of the night. 
	 A handful of connection cutoff issues throughout the night. 
	 Some other minor technical issues that are quickly resolved. 		 

Completed Programs: OSU_ASASSN/18jd/MODS (some period of clouds, took one extra exp)
		    OSU_ASASSN/18mx/MODS
		    ND_carbon/jyhe0017/MODS
		    ND_tau4/MODS (interchanging periods of thin vs thick clouds, took extra exp)
	            OSU_monitor/I2574
		    OSU_monitor/N3077/LBC-r
		    OSU_monitor/N2403/LBC-r
	            OSU_monitor/N925/LBC-r
	            OSU_monitor/N2903/LBC-r
	            OSU_monitor/M81/LBC-r
	            OSU_monitor/M82/LBC-r
         
Calibrations: finishing up the rest of MODS cals, morning twilights for LBC
		
Standard Stars: BD284201, Feige110

Details (All times UT):
-----------------------------------------------
23:47 - Began MODS1 calibrations
	Bias,grpixflats
	Two bias files (181029M8.074.fits,180930M8.0g8.fits) were named incorrectly, 
		but should still be good

	slitflats in 1x2 binning mode for 0.8" slit for ND_tau4 program
	(forgot to comment out the red-only and blue-only mode, so those are taken too)

00:30 - Opening up dome 

01:11 - Began standard star BD284201 
	still during twilight, may have a little blue contamination 
	Seeing was poor, around 2~3.  

01:21 - Began acquiring for OSU_ASASSN/18jd (UT 2)

01:44 - Began observing for 18jd 
	Seeing around 2
	Extinction and seeing fluctuated frequently. 

02:42 - Seeing around 2.5.  1-2 mags of extinction :'( 

02:53 - Took additional 1200s exposure for 18jd
	Seeing around 2-2.5, 2 magnitudes of extinction

03:15 - Began acquiring for ND_carbon/jyhe0017 

03:29 - Began exposures for jyhe0017 
	Extinction fluctuated, jumped up to 3-4 magnitudes

03:43 - Began acquiring for OSU_ASASSN/18mx (UT 3)
	Had to change to a brighter guide star due to cloud extinction 
	New guide star is NOMAD1 1101-0677051
	Checked to make sure the guide probe is not vignetting the slit

04:27 - Began exposures for 18mx
	Because of change to guide star, moved object 11" *below* chip boundaries 
		(rather than 11 arcsec above)
	Seeing around 2, extinction around 1-2 mags

05:25 - Seeing around 2, extinction jumped to 5 mags

05:34 - Began standard Feige110
	Seeing around 2, extinction around 1-2 mags

05:49 - Extinction jumped up 3 mags

06:05 - Began acquiring ND_tau4

06:21 - Began exposures for ND_tau4
	Seeing around 1.7, extinction around 0.5-1 mag

06:33 - Heavy clouds passed through for the first 2 images, also lost guide stars intermittently
	Can't see any trace in the spectra

06:50 - cleared a little, then clouds returned, 2-5 mags of extinction

07:41 - cleared a bit, 1-2 mags of extinction

08:27 - lost connection again

08:35 - done with ND_tau4
	taking extra 8 more exposures (~30 min) for the earlier bad weather

09:15 - switching to LBC-red
	taking test bias
	sky is clearing up

09:18 - began acquiring for OSU_monitor/I2574

09:28 - began exposures for I2574
	1 mag of extinction, seeing 1.5-1.7

09:42 - N3077 focus
09:44 - N3077 obs
	seeing 1.5-1.6

10:00 - N2403 focus
10:22 - N2403 obs
	seeing 1.3

10:09 - N925 focus
10:16 - N925 obs
	seeing 1.4

10:30 - seeing 1.6, clear
      
10:36 - RPC client - host comm failure
	lost the 3rd exposure 
	rerunning the obs and then stopping obs after the 3rd exposure, checked that the 2 re-do exposures read out in newdata

10:54 - N2903 focus
	seeing 1.5

11:04 - N2903 obs
	seeing 1.1, some thin clouds

11:45 - M81 focus
	seeing's been varying between 1.1-1.3

11:49 - M81 obs

12:02 - M82 focus
	
12:06 - M82 obs
	seeing 1.3

12:16 - done with M82 obs
	
01:09 - morning flats V+R, PA 0 and 180
01:17 - parking telescope to zenith
	taking biases
	finishing up the rest of mods cals
