The following just showed up from the other source I use for ISS transits and it agrees nicely with the data Kurt posted earlier. It's still a little low for my liking which puts it a bit more than twice as far away as when it's overhead (currently about 340 km) but as Kurt noted that's just the way it is for lunar transits this time of year. Note that column A refers to the travel distance from SPOC so if you're anywhere else, just ignore that column and plan any observations based on G and H. Patrick A - travel distance (kilometers) and direction B - date C - time (hhmmss) D - elevation angle of the ISS E - azimuth angle of the ISS ( + is East from North; - is W from N) F - range (kilometers) G - latitude for observing the transit H - longitude I - elevation above Mean Sea Level (meters) J - how far (kilometers) can I be from the centerline? (i.e., angular error = 0.25°) For other than solar transits: K - lunar transits: is space station sunlit? planetary encounters: 1=Mercury; 2=Venus; 4=Mars; 5=Jupiter; 6=Saturn L - sun elevation angle M - sun/moon or sun/planet separation angle A------- B----- C----- D--- E----- F--- G------- H-------- I--- J---- K L---- M---- 47.5 S 9 Jun 061543 1.6 60.7 2009 40.2259 -112.4502 1657 115.9 57.9 E 9 Jun 061544 2.1 61.1 1952 40.5200 -111.6323 2809 19.2 49.1 N 15 Jun 065650 22.5 -151.1 810 41.0744 -112.2280 1282 9.2 y 9.3 130.3 44.4 N 15 Jun 065651 22.5 -151.0 810 41.0235 -112.1675 1265 9.2 y 9.3 130.3 40.7 NE 15 Jun 065652 22.6 -150.9 808 40.9723 -112.1074 1265 9.2 y 9.3 130.3 38.1 NE 15 Jun 065653 22.6 -150.8 808 40.9210 -112.0474 1265 9.2 y 9.3 130.3 36.9 NE 15 Jun 065654 22.6 -150.8 808 40.8694 -111.9878 1286 9.0 y 9.4 130.3 37.3 NE 15 Jun 065655 22.6 -150.7 806 40.8181 -111.9279 1286 9.0 y 9.4 130.3 39.1 E 15 Jun 065656 22.7 -150.6 806 40.7652 -111.8696 1360 9.0 y 9.4 130.3 41.8 E 15 Jun 065657 22.7 -150.6 806 40.7094 -111.8132 1603 9.0 y 9.4 130.3 45.2 E 15 Jun 065658 22.7 -150.5 805 40.6424 -111.7652 2440 9.0 y 9.5 130.3
