Abstract

This is a literature review about the solar cycle and its variations, with a focus on sunspots. We also make a review of the different types of sunspot numbers currently in use and a comparison between their respective advantages and disadvantages, primarily focusing in their extension to the period between 1600 and 1900 AD.

Aurinkopilkkujen mittaus ja pitkäaikainen kehitys

Tiivistelmä

Tämä on kirjallisuuskatsaus aurinkosykleihin ja niiden variaatioihin, keskittyen auringonpilkkuihin. Tarkastelemme myös nykyään käytössä olevia auringonpilkkulukutyyppejä, sekä niiden etuja ja haittoja, keskittyen niiden laajentamiseen 1600-, ja 1900-lukujen välille.
