I assume that anybody here has heard about this by now. It's still a worthwhile sight in the evenings to come. I got photos of it on the three nights of closest approach, and by mixing in a long exposure for Saturn's moons (counterclockwise: Rhea, Tethys, Dione, Titan) with various exposures for other bodies, I got this photo with ten solar system bodies. A dim random star sidled alongside Ganymede.
Here is my best image, and an animation of the trio.

I also saw that star in my shots of the event, and it turns out to be a bit more interesting than just a random star. It's HIP 99314, and it was occulted by both Ganymede and Jupiter on the night of Dec 20-21: http://www.harvestmoonorchard.com/astro/oc...14_summary.html |

Here is a pic I took quite early on the 21st. 45x zoom using a 60mm spotting scope and pic snapped by IPhone 10. I seem to have caught Saturn in a very stable pocket of atmosphere. The view was much better with the naked eye, esp after the evening got darker.

Great pictures, everyone! I envy the views that some people got! It was a great reminder of how the population at large can get really excited about events like this.

It finally cleared in Vancouver Tuesday evening. I'm surprized there was some discussion about whether they'd be resolvable by eye - at 10'.5 they were easy to pick apart (even with my not-so-great eyesight) and I'm sure I could've at the minimum 6'. I guess viewing against a brightish sky helped and maybe Saturn could get lost in Jupiter's glare against a black sky?

In reality they did not get as close together as the general media had us believe. They were always resolvable to my spectacle corrected vision. |

Next up is the Mars/Uranus conjunction on 21 Jan 2021. That will be be harder to see as Uranus is so much dimmer.

That's the best I could do with poor conditions in south of France on Dec 22nd.

The most exciting thing about this conjunction is that finding Uranus will be finally achievable even for those of us who don't have go-to telescopes
