2/10/97: Airglow and 2MASS Observing Schedule Recommendations

IMAGES AND ANIMATIONS

The field in each frame is approximately 10 x 10 degrees. The intensity in each frame is scaled to +/- 5% to 8% the average intensity.

MOVIES

(Airglow movies have 15 seconds of time resolution per frame)

Here is a movie (243 kB) of Mike Skrutskie (left) and Joe Adams testing the 2MASS protoype camera on Kitt Peak before a long night of hard work.

Zenith 6/7/96: (Many contain the transit of the Galactic Plane)
h1.mpg (360 frames / 1.5 hrs.)
j1.mpg (180 frames / 45 min.)
h2.mpg (120 frames / 30 min.)
j2.mpg (180 frames)
h3.mpg (60 frames / 15 min.)
j3.mpg (60 frames) Contains moon ghost
h4.mpg (120 frames) "
j4.mpg (60 frames) "
h5.mpg (180 frames) "
j5.mpg (60 frames) "
jh.mpg (63 frames) Near simultaneous J-band (left) and H-band observations. The time lag between each side-by-side image is about one minute, while the frame-to-frame time is still 15 sec.

Zenith 6/8/96:
hzen1.mpg (420 frames / 1.75 hrs. This file is more than 9 MB!!!)
jzen1.mpg (120 frames) Frames 98 - 102 were taken in H-band. Despite any resemblance to reports of UFO activity in the area, the rapid bright objects were probably passing clouds (or possibly atmospheric effects from a thunderstorm along the SE horizon?).
hzen2.mpg (240 frames) Waves galore!
kszen.mpg (13 frames, 30 sec per frame) There is a 15 minute discontinuity in the middle here.
hzen3.mpg (60 frames)
hzen4.mpg (60 frames)

Horizon 6/8/96
hhor2.mpg (60 frames) Some wave activity captured along the right; towards the horizon (left) the observations are saturated.
