    How did sunspots get their names in the first place?

    Hi Becky,
    Sunspots look like dark spots on the Sun, so "sun-spots".
    I don't know who first used that term or first used it in English. The web page below describes early sunspot observations, and translates the title of a paper by Galileo
    as "Three Letters on Solar Spots..."
    http://galileo.rice.edu/sci/observations/sunspots.html

    Each particular sunspot group is also given a number, so we can distinguish them.
    These numbers are given by the National Oceanic and Atmospheric Administration (NOAA).
