Hisako Koyama, the amateur astronomer who drew sunspots for 50 years

I just can not help but notice if I think you never know when nature will show us something amazing.

The story of Hisako Koyama is at least surprising because he had all the tickets to have been a selfless Japanese woman and yet he became one of the people who most contributed to the study of the sun through sunspots in the last 400 years.

Born in Tokyo in 1916, she was fortunate that her father wanted to give her an education, which was at least rare at the time. So Hisako graduated from the institute's equivalent in the 1930s. His father also fostered her interest in heaven, and in 1944, World War II with or without it, Hisako began to observe the Sun with a telescope that had given him his father.

When she got her first drawing of what she thought were sunspots was sent to Professor Issei Yamamoto, president of the solar section of the Eastern Astronomical Association, who thanked her for her observation and confirmed that they were indeed sunspots.
That encouraged her to continue with her observations, which she continued to do until the early 1990s, even after she retired. In total, he left about 10,000 sunspot drawings.

Without ever abandoning his observations of the Sun as an amateur astronomer Hisako worked for 40 years in the National Museum of Science of Japan and in both the museum and in numerous publications contributed to popularize astronomy.
His colleagues from the Eastern Astronomical Association always held it in high esteem and showed admiration for his work, and in fact at the suggestion of S. Nakano, also a member of the AAO, the asteroid 1951 AB is called 3383 Koyama.
But without doubt the greater recognition is that its thousands of observations have become a fundamental part of a project that wants to normalize the observations of sunspots from 1600 to the beginning of 2000.

To this end, the project promoters look for groups of good observations made by a person for the longest time possible, since this helps to establish a kind of canon on which to normalize the observations of other people. And in the twentieth century the main source has been the illustrations of Hisako Koyama.

And all this thanks to a father who wanted his daughter to receive an education and supported her curiosity despite the standards of the time were on the other hand, in addition to the words of encouragement of Issei Yamamoto.
But how easy it would have been if she had never received such support, as it happens all too often even today when girls and teenagers are discouraged from pursuing careers in science, technology, engineering or mathematics.
