 Total Solar Eclipse of 2020 December 14
 in Argentina or Chile

The Covid-19 pandemic has thrown in disarray all the preparations for this eclipse and most participants or tour companies decided to cancel their trips over the past few months. As of November 23rd Chile will begin to reopen its borders to foreigners, yet still with numerous restrictions, and on December 7th the mandatory quarantine on arrival will be lifted. Argentina should start its reopening on December 4th, yet traveling to the eclipse path may not be easy. As often being patient and taking some risks are being rewarded. After weighting in also my options I had to settle down on the Chile one near Pucón where the weather prospects weren’t the best but viewing the eclipse from the slopes of the Villarrica volcano had some interest on a clear day.

Solar Corona, Baily’s Beads and Sky Simulations

The Baily’s beads simulations were generated using my Solar Eclipse Maestro application. The true photospheric solar radius used, 959.98" at 1au, is substantially bigger than the regular IAU (International Astronomical Union) value of 959.63" at 1au in order to fit the observations from the past 50 years. Be aware that a change of location by only a couple hundred meters is sufficient to alter the Baily’s beads sequence.
For the predictions on the shape of the solar corona on December 14th please consult the Predictive Science, Inc. webpages. You can also compare with the results of the 2019 July 2nd and 2017 August 21st eclipses. The preliminary predictions will be released publicly on November 27th and the final ones on December 7th.
During the early morning hours before the eclipse, observers looking towards the northern horizon will be rewarded by the peak of the Geminids meteor shower. Plus lets not forget an additional guest, the comet Erasmus C/2020 S3, which will show up; there is a small chance it will be visible naked eye during totality.

From the Refugio de Sky the Baily’s beads will also be quite nice particularly at second contact.
