Looks like ISS's orbit have changed slightly so the original plan for observing it would need to be reworked. However, in communicating with others that watch ISS transits, we've pretty much agreed that a transit that low in the sky (rendering ISS far away and very small) is probably a waste of time. Better to wait for one that happens much higher in the sky. So, I'll not be trying for Sunday's pass but will will let y'all know when a better one comes along. Personally, I'd love to see an illuminated (so you can see it coming) ISS pass in front of the Moon (no filters required) in the 60 to 90 degree altitude range (closer and bigger) at a public star party (so lots could see it) at SPOC (easy to video). Do you think I'm being too picky? :-) Patrick :-)
