---- Observing Plan ----
BOSS all night
---- Observing Summary ----
An overcast and windy night. Never opened. We did dithered flats for cartridges
10, 11 and 13.
A flat-field lamp burned out. We replaced it with the only spare, and put the bad
lamp on Wendell's desk.
---- Observing Log ----
Afternoon:
---------
0039Z - No problems noted during afternoon checkout.
All actors checked and found alive.
Cartridge 10 mounted.
Spectrograph collimation checked on cartridge 10, and in spec.
0046Z - Started ventilation.
0052Z - Clouds getting too thick for useful science exposures. We continue to
ventilate, and wait for a break.
Night:
------
0212Z - Still cloudy. We start dithered flats on cartridge 10.
        Collimation adjusted - frames 127125 - 127128.
0229Z - Dithered flat sequence - frames 127129 - 127150
        Final Hartmann sequence - frames 127151, 127152
0334Z - Ventilation off.
0345Z - Cartridge 11 mounted for dithered flats
        Collimation checked - frames 127153 - 127154
        Regular flat and arc - frames 127155, 127156
        Dithered flat sequence - frames 127157 - 127178
        Final Hartmann sequence - frames 127179, 127180
0505Z - Cartridge 13 mounted for dithered flats
****N.B. A flat field lamp burned out during this sequence.*******
******************** Not useful data *****************************
        Collimation adjusted - frames 127181 - 127184
        Regular flat and arc - frames 127185, 127186
        Dithered flat sequence - frames 127187 - 127208
0616Z - Replaced ff lamp on lower north side. Repeat the dithered flat sequence
on Cartridge 13.
        Collimation checked - frames 127209 - 127210
        Regular flat and arc - frames 127211, 127212
        Dithered flat sequence - frames 127213 - 127234
        Final Hartmann sequence - frames 127235, 127236
1055Z - Re-started ventilation. Clouds thinning, but wind still over the limit.
1206Z - Despite a tempting sucker hole at the end of the night (which quickly
filled back in), we never had conditions where we could open. We gave up.
