WIYN 3.5m WHIRC Observing Report for 2013/09/25

Summary:

We observed 5 supernovae 2 standard stars and 1 host galaxy from 2011B. Here is a summary of observations:

P525-E in JHKs at 1.7 airmass and P161-D at 1.57, 1.22, and 1.13 airmasses.

Observer: Anja Weyant with Kara, Michael D., and Nabila until midnight
Telescope Operator: Krissy
Conditions:
wind: 30 mph
Humidity: 25.9
Temperature: 19.7 C
Gusts of wind near dome-closing speeds.  Had to stay pointed to the North
Seeing: .6-2.5" Seeing was greater than 2" from 22:00-01.00
Moon: 58%

Notes:

Up in focus is still tilted, top left to bottom right.  Down in focus is now
just left to right.  Unfortunately this looks like wind shake.

"the images are astigmatic, pronounced, when defocused.  This is good for determining focus direction but bad for ultimate image quality.  We seemed to note that the orientation of the astigmatism has changed.  When the focus value is too high, the astigmatism is left right, elliptical left/right, not at a 45.  "

Winds were 30+ mph coming in from the South.  Therefore, we could not physically look at any targets in the South
as the winds were beyond the allowable limit.  So we had to stay pointed in the North.  This basically
meant that we could only look at iPTF13ddg, iPTF13dad, and SNhunt206.  

The seeing was particularly bad (2.5"+) from 23:00-01:00, so I spend a long time on iPTF13ddg.  I hope there are
some useful images in here.

The seeing improved around 01:00 to about 0.7" so I was able to continue with SNHunt206 and iPTF13dad.

When I moved to P161-D the seeing started to get worse and it was pretty bad by the time I got to PTF11qzq (back to 1.5") so I am not that we can use these images to make a host galaxy template but we had nothing else to observe at this point.

Took 605 images.
