Photospheric Continuum Photoheliograms
Observations and Ancillary Data Request Form

Kanzelhöhe Full-Disk Continuum Photoheliograms show the solar photosphere at 546 nm/10 nm FWHM. They were taken from 1989 to mid 2007 on BW-film plates 13x18 cm with a refractor d/f = 13/195 cm. The disk diameter on the film slide is enlarged to about 87 mm, a synoptic set of 3 exposures is taken daily if weather permits. The angles eta which are given in the query result are used for proper orientation of the film slides.

The film plates are not scanned and digitized as a standard procedure, therefore this catalogue denotes only the availability of observations.
