Total eclipse duration 4 m 6 s |
| Place | Libya, Sahara, 92.6 km eastward of Valley of the Mosquitoes |
| Coordinate | N 24° 33' 59", E 17° 57' 16'', altitude 439 m |
| Conditions | Excellent - clear sky, altitude of the Sun above the horizon 67° |
| Optics | Lens: Nikon 300 mm
On-band filter: Andover, 0.5 nm bandpass, centered at 789.2 nm,
Off-band filter: the same as on-band, tilted by 7°, centered at 787 nm |
| Camera | Princeton Instruments PIXIS 1024BR |
| Exposure | Two sequences 7, 2, and 0.5 s (one on-band, one off band) |
| Processing | Composition of 6 (3 on-band, 3 off-band) images. Images were aligned by means of phase correlation, composed by means of LDIC 4.0 software, processed using Corona 4.0 in order to visualize coronal structures. Final processing was done using ACC 6.0 software.
