Elsewhere in the solar system IR Keck images of Neptune and Uranus (more and more), amateur images of Jupiter of Oct. 1, Sep. 26 (also w/8" - and structure on Ganymede!) and Sep. 22, and Mars on Sep. 26. • NEOWISE has revised the statistics of NEOs (alt., ident.; coverage here, here, here, here and hier) and the history of the Chicxulub impactor (covered here, here, here, here, hier and hier); the latter's role in the dino death is still under debate, by the way. • Among comets there were a bright Kreutz, lots of structure in 45P/H-M-P's tail & Jupiter near-crash (H-M-P today), new main belt comet P/2010 R2 (La Sagra), further fragmentation in 213P/van Ness (more, more), new comet Gibbs, no LASCO sighting of damaged Elenin and a naked-eye sighting of Garradd (which did not fade afterwards); also picture of Sep.30, Sep. 26(!), Sep. 24 and Sep. 21.
Sky highlights in October - see overview articles here, hier and here - include:
- Oct. 1-2: Mars passes Praesepe, the star cluster.
- Oct. 8 (around 20:00 UTC): Possible outburst of the Draconids (more, more), but the predictions remain confusing - and the event coincides with Observe the Moon Night which is not a good night for meteor watching ...
- Oct. 21-22: Peak of the Orionids; less lunar interference than with the Draconids, so worth a look.
- Oct. 27/8: Conjunction of Moon, Venus and Mercury low in the evening, invisible in higher N latitudes.
- Oct. 29: Jupiter in opposition with -2.9 mag.; it's awfully bright already now (closest to Earth on Oct. 27 already).
