On November 2, 1958, the Russian astronomer Nikolai A.Based on repeat observations, he further stated that " Linné can never be seen under any illumination as a crater of the normal type" and that "a local change has taken place." Today, Linné is visible as a normal young impact crater with a diameter of about 1.5 miles (2.4 km). Schröter, as well as personal observations and drawings made between 18, he stated that the crater "at the time of oblique illumination cannot at all be seen" (his emphasis), whereas at high illumination, it was visible as a bright spot. Julius Schmidt made the claim that Linné crater had changed its appearance. In 1866, the experienced lunar observer and mapmaker J.Padua's display and Herschel's observations had happened a few days before the sunspot number had peaked in May 1787. Aurora activity that far south from the Arctic Circle was very rare. ![]() His observations were made while an aurora borealis (northern lights) rippled above Padua, Italy. Herschel attributed the phenomena to erupting volcanoes and perceived the luminosity of the brightest of the three as greater than the brightness of a comet that had been discovered on April 10. He informed King George III and other astronomers of his observations.
