Well, I certainly wasn't trying to be secretive. Yes, I'm the "anonymous source" for Chuck's later information. It was late enough last night when I saw Chuck's email that I simply responded to him directly. No offense intended towards anyone, especially not you, Guy. I just got different results. I've found with Sky Map Pro that I have to be very careful when I use a time and/or location other than the default. It's easy for me to forget to click on "OK" when I make a change, so I double- and triple-check, as I did last night. From Bern, Switzerland, I got the following: Information about Moon for 14 Oct 1918 10:30:00 PM (Julian day number 2421881.39583) Local Information Apparent topocentric coordinates for the epoch of date: Right ascension: 20h 49m 51.06s Declination: -13° 58' 11.5" Constellation: Aquarius Altitude: 19° 20' 40" Azimuth: 221° 27' 6" Rise: 14h 40m 36s Transit: 19h 45m 47s Geocentric Information Apparent geocentric coordinates for the epoch of date: Right ascension: 20h 51m 36.823s Declination: -13° 9' 31.01" True distance: 374979.6 Km Horizontal parallax: 3508.59" Physical Information Magnitude: -10.8 Phase: 0.679 Phase angle: 69.0° Elongation: 110.9° Diameter: 1923.51" Light time: 0h 0m 1.3s Information about Jupiter for 14 Oct 1918 10:30:00 PM (Julian day number 2421881.39583) Local Information Apparent topocentric coordinates for the epoch of date: Right ascension: 7h 5m 54.32s Declination: +22° 27' 11.4" Constellation: Gemini Altitude: 1° 39' 36" Azimuth: 57° 39' 58" Rise: 22h 16m 43s Transit: 6h 8m 14s Set: 13h 56m 7s Geocentric Information Apparent geocentric coordinates for the epoch of date: Right ascension: 7h 5m 54.236s Declination: +22° 27' 12.76" True distance: 4.9587437 AU (742 million km) Horizontal parallax: 1.77" Heliocentric Information Ecliptic coordinates for the epoch of date: Ecliptic longitude: 94° 5' 7.0" Ecliptic latitude: -0° 7' 32.4" Radius vector: 5.1513854 AU (771 million km) Physical Information Magnitude: -2.3 Phase: 0.991 Phase angle: 11.1° Elongation: 95.5° Equatorial diameter: 39.70" Polar diameter: 37.13" Light time: 0h 41m 14.4s I just saw Jim's latest post. I, too, wondered if even the light of Jupiter was bright enough to really aid in seeing anything. The Moon would not have set below the ideal horizon until nearly 1:00 AM on the 15th. We've all observed how bright the sky can be if a bright Moon is just below our local horizon in the mountains. Perhaps the moonlight is really what aided the escapees, even though it may have been below their local horizon, and so they attributed the greater visibility to "some planet or other." Thoughts? I would be interested to know if anyone with a different program gets significantly different results. Please check the time (14 Oct, 1918 AD/CE, 22:30 local time, or 21:30 UT) and location (Bern, Switzerland, lat. 46:57:0, long. 7:25:48). I hope my Sky Map Pro is reliable, as it's the only program I've got for such stuff, and I've used it to research other historical questions. Kim
