The total solar eclipse of 1994 November 3, was photographed from Putre, Chile, by a research team from the High Altitude Observatory of the National Center for Atmospheric Research, Boulder, Colorado. The expedition was sponsored by the National Science Foundation. The photograph of the solar corona was taken with a camera system developed by Gordon A. Newkirk, Jr. This specialized instrument photographs the corona in red light, 6500 A -- through a radially graded filter that suppresses the bright inner corona in order to show the much fainter streamers of the outer corona in the same photograph. As the photograph was taken late in the eclipse, prominences on the west limb are visible. Other features of note are the polar plumes, and the non-radial nature of the southwestern streamer. An additional highlight of the SW streamer was a coronal mass ejection observed in its vicinity by the Mauna Loa Solar Observatory approximately 10 hours after the eclipse.

Vertical (top) is geocentric north. Left, (9 o'clock) is east. To assist in orientation, the brightest prominences are on the WEST limb. There is one major streamer on the EAST limb, two on the WEST limb, with the brightest western streamer being the one to the SOUTH. Objective aperture 11.4 cm Focal length 178 cm Focal ratio f/15 Film Kodak Technical Pan / 2415 Development D19 - 5 minutes (Film was developed at Sacramento Peak Observatory by Todd Brown) Wavelength isolation filer - Schott OG-3 Effective wavelength - 6500 A Exposure 25 seconds Radial filter range - 10^4 in transmission. Note: There are round dark circular artifacts in the image. These are the result of out of focus dust within the telescope. ftp instructions follow: ftp 128.117.16.39 or ftp puu.hao.ucar.edu anonymous enter some identification, such as your email address cd mk3/pub/eclipse94 get data_descrip_WLCC94_exp4 binary get WLCC94_exp4.tif quit
