Sunspots registry – Program run since 1826
Sunspots registry – The longest regular scientific research in the world is the record of the number of spots on the Sun created since 1826.
The research program was initiated by the German amateur astronomer Samuel Heinrich Schwabe. He watched the Sun regularly for 17 years because he wanted to observe a planet previously unknown to science called the Volcano.
Moving against the backdrop of the solar disk. Of course, he found nothing – only Mercury and Venus are between Earth and the Sun. Known since antiquity – but his observations have determined that the activity of our nearest star changes regularly.
Schwabe’s achievements inspired Rudolf Wolf, head of the Bern observatory. Which from 1848 continued to record spots and collected historical data on this subject. Dating back to the early 17th century
