1. Annular Eclipse on May 21, 2012

Realtime Data

'Himawari' Meteorological Satellite Imagery

This page is planned to provide a real-time relay from space for the annular eclipse on May 21, 2012 using the geostationary meteorological satellite "Himawari." How images and videos from the ground site is different from those from the space? You can see an example of the image at Total Solar Eclipse on July 22, 2009 or Annular Solar Eclipse on August 22, 1998.

The unique point of the relay on this page is that the viewpoint is located at 35,800 km above ground, so you can see the solar eclipse for certain even when the weather is cloudy, rainy, or stormy with typhoons.

AMeDAS Sunshine Duration

AMeDAS is used not only for measuring rains and winds, but also for measuring sunshine duration at some stations. We may be able to observe the effect of eclipse as the change of sunshine duration, as long as the weather is good.
