In evening of Mar 20, 2002, the second Saturnian occultation in this year was observed in eastern Japan. The last one on Jan 25, the Saturn was grazed the northern edge of the Moon, but this case the planet was hidden behind near the southern edge of moon. The Saturn with the ring full-opened was occulted by the dark edge of the moon spending about 3 minutes, and 15 minutes later the planet appeared again slowly from the bright rim.
In the year of 2002 we have luckily two times of such a rare event in Japan, but the next Saturnian occultation will not occur untill June 2007.
