Asteroid / Meteoroid C21VL72 passed by earth within the orbits of the geosynchronous satellites. This is a plot of all satellites with a period of > 600 minutes with a TLE in the space track database. I generated… https://www.instagram.com/p/B8LURJFB4Tv/?igshid=mqxwk2go8qh4 …

Based on the AMS-posted position and velocity on facebook, the LA Meteor ~ a=2.90461 AU e=0.677288 i=2.60827° ω=151.679° Ω=309.545° q=0.937354 AU Q=4.87187 AU and it would have been in the sky over the

January 27 cneos meteor over Algeria: I get ~ a=1.65374 AU e=0.494289 i=21.0851° ω=122.999° Ω=306.47° q=0.836315 AU Q=2.47117 AUpic.twitter.com/Boo6sk0zEx

May as well tweet the lunar-distance version too: 2020 BH6 CA encounterpic.twitter.com/r4Zr3yUfjY

To correct myself on a comment on
@tony873004 ’s 2020 BH6 CA, I forgot to rotate the satellites into the proper frame (though simulation was correct, impacted drawing only). Done now, sat color = inclination 0º=red increase toward blue:pic.twitter.com/GUd4B3ZLfBHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -
Another meteor appeared in cneos, it seems we’re on a roll for low-ish inclination, aphelion around jupiter’s orbit meteors:pic.twitter.com/ORW8dsWhkU

First cut of an orbit for the Puerto Rico meteor (based on cneos, no atmosphere modeled yet): a=3.77585 AU e=0.741842 i=7.25614° ω=11.857° Ω=116.989° q=0.974769 AU Q=6.57694 AU (discard pedantic non-significant figures) - did anyone else do an orbit for it yet, I want to comparepic.twitter.com/t3OB5E3WfW

New CNEOS meteor: 2020-1-16 09:31:42. Very approximate (I ran without atmosphere deceleration modeled this time) elements: a=1.70613 AU e=0.424504 i=4.87846° ω=6.20021° Ω=115.613° q=0.98187 AU Q=2.43039 AU (Ceres is the outer plotted orbit)pic.twitter.com/SNdH6knZDb

New meteor! (this based on the chicken little velocity, which I’ve not been really sure about) - a=0.675291 AU e=0.584336 i=46.2755° ω=339.619° Ω=279.849° (note that gives a perihelion inside Mercury’s orbit). (skyfall page: https://fireballs.ndc.nasa.gov/skyfalls/ )pic.twitter.com/JTLzQO6xok

Comet C/2017 T2 and another Russian photobomber - Cosmos 2492, a Glonass satellite. I had checked for Starlink and of course those were all well within Earth’s shadow. But this satellite wasn’t.pic.twitter.com/fSuOchMHDZ

The meteor I talked about in my last tweet was probably reported as https://fireball.amsmeteors.org/members/imo_view/event/2019/6724 … - I’ll take a very wild guess at 65 cm radius and 3500 kg mass from ~875 GJ (0.21kt) energy. aprox view presuming luminous flight began ~110km alt 467km @ 175º az from Anchoragepic.twitter.com/yqGPqsEqYl
