Date | 22. 07. 2009 |
Time | 2nd contact 03:28:39 UT, 3rd contact 03:34:20 UT Total eclipse duration 5 m 41 s |
Place | Enewetak Atoll, Marshall Islands |
Coordinate | 11° 21.546' N, 162° 20.827' E, 3 m altitude |
Conditions | Partially clear, partially small cumulus cloud, altitude of the Sun above the horizon 56-57° |
Optics | Canon 200mm 1:2.8 L II Maksutov-Cassegrain 3M-6A, 6.3/500 mm |
Camera | Canon EOS 5D Hutech Ia modification (Canon 200mm lens) Canon EOS 5D (Maksutov-Cassegrain) |
Exposure | 1/500 s - 1 s (Canon 200mm lens) 1/250 s - 8 s (Maksutov-Cassegrain) |
Processing | Composition of 9 images (Canon 200mm lens) and 38 (Maksutov-Cassegrain) eclipse images. Eclipse images calibrated by means of dark frames and flat-fields, aligned by means of phase correlation, composed by means of LDIC 5.0 software, processed using Corona 4.1 in order to visualize coronal structures. Final processing was done using ACC 6.1 software. Image processing by Miloslav Druckmüller |
Software | Astro D3F 2.0, PhaseCorr 6.0, MPA 1.0, LDIC 5.0, Corona 4.1, Sofo ACC 6.1 |
Note | The graph above the table shows the average values of the relative number of sunspots in which the red line indicates the time of 2009 eclipse. The data from the World Data Center for the sunspot index, (Solar Influences Data Analysis Center, the Royal Observatory of Belgium) were used. |
