End of summer 2014 observations
The Winter Triangle and the Winter Hexagon appear briefly in my early
morning sky at 43 deg N. After each appearance they become invisible a short time later due to the Sun. Each appearance lasts a little longer than the previous morning's. Jupiter appears further East of Gemini since last Winter. Ares, Taurus, Gemini, are easy to spot on a clear night, along with Pegasus and others. Pegasus and a few others also remain visible in the early night sky. In the early night sky it's easy to see Scorpius, Sagittarius, and Capricornus. Mars' retrograde motion relative to Saturn surprises me (this time around). -- Don Kuenz |

The orbital period of Uranus is well over twice the length of time of Saturn and considerably more distant however retrogrades are seen as the Earth overtakes both these planets - http://apod.nasa.gov/apod/ap031216.html Likewise the same with the closer Jupiter and Saturn as both are seen to temporarily fall behind in view as the Earth overtakes them when gauged against the background stars - http://apod.nasa.gov/apod/image/0112/JuSa2000_tezel.gif These observational reports become relevant in context of the actual motions of objects and even the ecliptic motion of the constellations behind the Sun due to the orbital motion of the Earth. Nobody loses anything by being tighter with observations rather than lapse into the willy, nilly celestial sphere view. I am sure by now that readers in saa are ready for more accurate and more relevant astronomical reports otherwise you can retreat to the moderated forums where they will give you a title or scold you. Carry on. |

Carry on. Hmmm. How better to phrase that? The absolute position of Mars' retrograde relative to Saturn's retrograde? Mars' appearance to the South of Saturn? Let's just call it Mars' planetary dance with Jupiter. Here's an open question (to me). Have the two planets finished their do-si-do this time around, or are they still in the middle of it? -- Don Kuenz |
