Coronal Observations at the Siberian 2008 Total Solar Eclipse
Abstract
We successfully observed the 1 August 2008 total solar eclipse from the rooftop observatory of the State University of Novosibirsk in Akademgorodok, Siberia, latitude 55° N at 10:45 UT in clear skies and also from an airplane at 83° N latitude north of Svalbard at 9:43 UT. Our prime experiment in Akademgorodok was a set of high-cadence, 10 Hz, observations in the coronal green line at 530.3 nm from [Fe XIV] to verify and extend our previous findings of excess power in the 0.5 Hz to 1 Hz region as predicted by a subset of coronal-heating theories. We used twin 0.2-m telescopes with narrow-band interference filters and our POETS frame-transfer CCD's on the university's Paramount ME. Additional photography included graded-exposure sets of images meant for post-processing to compare with images taken earlier from the airplane and later from the ground in Mongolia and China to provide time differences of over 90 minutes. We also obtained HD video. Our comparison of the images from the airplane and from Siberia will be used to search for coronal motions.
