Partial Eclipse

Hinode saw the passage of the Moon on February 17 from its orbit, which was not observed from the ground. Southern part of the Sun was obscured by the northern part of the Moon.

Shadow of Craters on the Moon were found by Solar Optical Telescope (SOT) whose resolution is 0.2 arcsec, or 400m on the Moon. Several craters on the Moon were identified from the image. In principle, image processing allows to determine geography of the Moon with 10 times better accuracy. These data are valuable to be compared with the topography measured with RISE instrument on SELENE mission led by JAXA, which is going to be launched in Summer 2007.

Eclipse data obtained by Hinode will be used to determine scattered light of the telescopes, which are crucial for precise measurement.
