Illum.exeソフト (by DK3WN) で確認すると、2013年6月10日00:56JST は、LO-19
が日本上空で蝕に入る、まさにその瞬間の時刻でした。LO-19 は、打ち上げから
23年が経過しニッカドバッテリの充電放電が 122,140回も繰り返されて、もはや
充電の機能は失われているので、日照時のみの動作になっているということです。
I was examined using the Illum Software(by DK3WN) for the period of
Eclipse(Shadow) of LO-19. It was found that 15:56 UTC, 9 June 2013
was exactly the beginning of Eclipese over Japan.
