Uncannily, the weather remained clear throughout the run. A small amount of time was lost one night due to telescope closure for smoke from the forest fires happening elsewhere in Arizona. Some cirrus was present during the first three nights, but thereafter conditions were largely photometric. Warm weather resulted in a relatively bright K-band background.
Altogether, 22.9 hours of data were collected in the K-band, along with 11.0 hours at J and 11.3 hours at H. Net image quality in the combined images produced on-line at the telescope is 1.0 arcsec FWHM.
In addition, about half the flanking field area was covered with 24 minute K-band exposures. Fields to the east and north of the central HDF were observed.
Data reduction and calibration are currently underway.
