Abstract:
Simultaneous observations of the solar corona and the photometric standard
stars make possible to calibrate the corona radiation in the BVR system. A
possibility for such observations during the 1999 solar eclipse is proposed.
For the observations we suppose to use a system consisting of a simple camera
obscura and a CCD video camera ICD-42 B (699x576 pixels) with an enhanced
sensitivity. It enables to detect 0.06 lux as a minimal registrated light flux.
We plan to observe a 10 arc degrees field of view that provides us a sufficient
amount of etalon stars for the calibration. Images of the solar corona and
etalon stars obtained with use of B, V, R filters will be recorded on the VCR.
The CCD photometer and the suggested method of data reduction and analysis are
described.
