We report on our eclipse expedition to Kastellorizo, Greece, in the Dodecanese off the Turkish coast. We observed 3 min 00 sec of totality on 29 March 2006. All our observations worked very well. One of them was high-time-resolution (10 Hz) observations in the coronal green line looking at coronal loops; another was similar observations in the coronal red line; both are to determine among theories of coronal heating and continue earlier reports of excess Fourier power in the 1 Hz range. As we knew from SOHO observations from the day before the eclipse, an active region was stationed right on the east limb and it gave us very suitable loops to study, with pointing in agreement with TRACE. A third set of observations used a very narrow-band filter (Fabry-Perot), with 1/6 angstrom resolution, to make velocity (Doppler) images of the same coronal loops. A fourth set of observations used a telescope we had built to match the size of the now defunct innermost coronagraph on the NASA/ESA SOHO, and it indeed was used to merge with SOHO EIT disk coronal images and SOHO LASCO outer coronal coronagraph images. Further, radial-filter "Newkirk camera" images captured the role of magnetic fields in shaping coronal streamers, which we also display in mergers of images with sequential exposure times.
The expedition was supported by NSF (ATM-0552116), the Committee for Research and Exploration of the National Geographic Society, NASA's Planetary Astronomy Division for the CCD cameras (NNG04GE48G), Sigma Xi, and the Rob Spring Fund and the Ryan Patrick Gaishin Fund at Williams College.
