Corona in white light and EUV
The part of the solar image which was during the total solar eclipse occulted by the Moon was replaced by SDO
AIA data acquired in EUV spectral range. 304 A, 171 A and 211 A images processed by means of PM-NAFE
algorithm acquired during the time of total solar eclipse were used. The full resolution version of this

| Time | 2nd contact 07:45:00 UT, 3rd contact 07:45:38 UT |
| Place | Union Glacier, Antarctica |
| Coordinate | S 79° 44.340', W 82° 44.195', Alt. 715 m |
| Conditions | Clear sky, Solar altitude at mid-eclipse 13.9° above horizon |
| Optics | Nikkor 80-400mm 1:4.5-5.6G ED VR (set to FL 400 mm, F5.6) |
| Camera | Nikon Z6 |
| Exposure | 1/400 s - 2 s, ISO 100 |
| Processing | Composition of 24 eclipse images. Eclipse images were calibrated by means of dark frames and flat-fields, aligned by means of phase correlation, composed by means of LDIC 6.0 software, processed using Corona 6.0 in order to visualize coronal structures. Final processing was done using ACC 6.1 software.
