After passing over Ontario and Quebec, to the N of the St Lawrence, it crosses the N Atlantic to N Spain (05:41), and N Africa to reach a southbound equator crossing at 05:56 at 41 deg E, over Kenya. It continues south-eastwards across in the Indian Ocean and well S of Australia before reaching Auckland, New Zealand, at 06:27. The following northbound equator crossing is due at 150 deg W longitude at 06:39 and it is here that I now place its decay. If it survives, the following orbit would carry it across the USA from N of Los Angeles (06:51) to Fargo, N Dakota, at 06:56, thence again over SE Canada.
