Getting ready for three Japanese eclipses in the next 18 months…

“OK, so if the earth is here…”

In 2019 Japan will experience two partial solar eclipses. The first comes at the start of the year, on the morning of Sunday 6 January 2019. The second comes at the end of year, on the afternoon of Thursday 26 December 2019. Six months after that, on 21 June 2020, Japan will witness its third partial eclipse within 18 months — but it will then have to wait ten years until the next one…

This week I gave a presentation about the eclipses at a study camp organised by Omikyodaisha, an amazingly inspiring high school in the city of Omihachiman. We had fun thinking about how big — and how far away — the moon and sun would be if the earth was 10 centimetres in diameter. We also asked ourselves: if the moon goes round the earth every 29.5 days, why isn’t there an eclipse every month…?

The school funded 200 pairs of eclipse glasses to give to its students. Thank you to Takeshi Taniguchi, Noriko Nishimura, and the fabulous students at Omikyodaisha for a hugely enjoyable session!


IMPORTANT: NEVER look at the sun with the naked eye.
