#comet 2I/Borisov reaches perihelion today: the closest it will be to our sun... ever. Contrary to my earlier tweet, closest approach to earth will be on December 28. (Thanks@cbellh47 for spotting a big booboo in my previous tweet) See http://astro.vanbuitenen.nl/comet/2I pic.twitter.com/BU3hjfyA0z

https://www.nature.com/articles/d41586-019-03530-3 … Great
@nature article about interstellar visitors. A bit dismissive about the cool stuff we already learned from ‘Oumuamua, e.g. that it is accelerating away from the sun. But mentions@CometIntercept at the end. The excitement grows!Hvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -

If we're very lucky, our mission could encounter a body from another star system. More on these interstellar wanderers here, with input from our team members

The latest JPL Horizons orbit update by Davide Farnocchia with solution date 2019-Nov-19 11:40:51 for 2I/Borisov specifies values for nongravitational parameters A1, A2, and A3 and perihelion offset DT. These inputs should improve calculations for where 2I came from.pic.twitter.com/klJoBsNIf9

Interstellar comet 2I/Borisov on 2019-Nov-02 11:12:05 UTC is brightening and has a short stubby dust tail toward the northwest. 2I is 36 days away from perihelion passage

If we could predict stellar occultations by comet 2I/Borisov with some reasonable accuracy the favorable time window for observing them will be between 2020 mid March and mid May wrt to the max. occultation duration. But it would happen on the southern hemisphere.pic.twitter.com/Y3uUVHPGjS

#2IBorisov is a severely C2-depleted interstellar comet, from WHT & INT spectra Sep 30 & Oct 13. CN production and dust coma colours are consistent through time.

*Submitted!* We found C2 for the *first* time in
#2iborisov using the Bok and MMT telescopes, which when combined with our CN measurements (consistent with the Fitzsimmons paper) suggests that 2I/Borisov is carbon-chain depleted.
