Experimental Reconstruction of Lomonosov's Discovery of Venus's Atmosphere with Antique Refractors During the 2012 Transit of Venus

TL;DR

This study reenacts Lomonosov's historic discovery of Venus's atmosphere using antique telescopes during the 2012 transit, demonstrating the effectiveness of 18th-century observational techniques.

Contribution

It provides experimental evidence that Lomonosov's original methods with antique refractors were sufficient to detect Venus's atmosphere during transit.

Findings

Antique refractors can detect Venus's atmospheric arc with proper techniques.

Lomonosov's original observational methods are validated by reenactment.

The 2012 transit allowed successful experimental reconstruction of the historic discovery.

Abstract

In 1761, the Russian polymath Mikhail Vasilievich Lomonosov (1711-1765) discovered the atmosphere of Venus during its transit over the Sun's disc. In this paper we report on experimental reenactments of Lomonosov's discovery with antique refractors during the transit of Venus June 5-6, 2012. We conclude that Lomonosov's telescope was fully adequate to the task of detecting the arc of light around Venus off the Sun's disc during ingress or egress if proper experimental techniques as described by Lomonosov in his 1761 report are employed.
