81 seconds animation
This animation showing 81 seconds long time interval illustrates that even during the total solar eclipse
it is possible to observe changes in the solar corona. It is possible to distinguish between structures which
belong to the moving CME and relatively stable coronal structures.

| Coordinate | S 39° 57.680', W 69° 59.576', Alt. 485 m |
| Conditions | Clear sky for 85 s of totality otherwise thin clouds
Solar altitude at mid-eclipse 72.4° above horizon |
| Optics | Nikkor 80-400mm 1:4.5-5.6G ED VR (set to FL 400 mm, F5.6) |
| Camera | Nikon Z6 |
| Exposure | 1/640 s - 3 s, ISO 100 |
| Processing | Composition of 55 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.
