6 March 1996 - 12:40PM Hawaii
Last night, the winds continued to get higher and higher. The telescope operator waited until the last possible moment, and then opened the dome for us. We went immediately to Jupiter, which was just rising. Our plan was to take a picture, then center our camera on the part of the planet where the star was supposed to pop out from behind the planet. When we took our picture, all of us groaned in disappointment. Instead of a nice clear picture of Jupiter, all we saw was a big fat fuzzy blur. The general atmospheric conditions were just poor, probably due to turbulence created by the the very high winds.
We set up on the planet anyway, and started our instrument running. It was supposed to focus on a small part of the planet where the star would be, and read out data very very fast. We were supposed to use the edge of Jupiter to guide the telescope, but because of the bad seeing, all we could see was blurry fuzziness. We took data anyway, because you have to take data. When the scheduled time of the event had passed (and we saw nothing more than blurry patches of light), we stopped the experiment and took a regular picture. We could see the star - it had popped out right on time. But because we could see the limb of Jupiter, the telescope had drifted, and we probably did not get useful data. We were all pretty depressed. But we went ahead and took all our calibration data anyway, since we may be able to salvage something when we get back to MIT and can take a closer look.
We finally shut down at 4:45 am, and then spent an hour and half taking our camera off the telescope and packing it back into the crates. Lots of sighs. We loaded up the truck and drove down the mountain, talking about how we might have done things differently, and trying to learn from this unsuccessful experience what we need to do for future events. We all went to sleep for a few hours, and now we are about to head down the mountain, to the airport, to begin the long trip back to MIT.
In astronomy, you do everything you can to prepare for your observations, but you can't do anything about the weather except hope for the best. Sometimes you win, and the mysteries of the heavens are yours to savor. Other times, the skies hold their secrets close, and all you can do is imagine what might have been.
