Hello Group, 2:1 for 27000km ;) Thank you for analysis! I will check the algorithms to detect the cause of discrepancy... But the prinicpal detection algorithm...
At 2009-Oct-19 minimum distance between nominal orbits of asteroids 3313 and 2006BF190 is about 27000 km. It is the least distance around this date. ...
... According to my software Solex/Exorb, the minimum distance was about double of that: 25900 - 27900 km (2-sigma) at 23:49 +/- 4 min (UT) of Oct 18 Regards ...
Hello Group Members, this is my first post here and a request for a asteroid flyby investigation :) A numerical simulation based on SDM indicated a close flyby...
Thanks for checking. I'll be interested to see what you find. It definitely was bright. I was sitting in my warm room with the curtains closed and it was so...
Hi Patrick, I'll check the NexRad Doppler radar for the region when the data gets archived on Thursday. If the bolide was large enough, and close enough to one...
About 07:07:05 UT today a brilliant bolide broke up and lit up the sky over northern Utah. Five minutes later, almost to the second, I heard a low rumbling...

Dear Giovanni, Some meteorites and presumably asteroids contain a significant proportion of hydrated minerals. Energetic particles from a solar flare would...
Andrew, ... Yes, but it wasn't discovered at all in the 60ies and neither in the course of the original Palomar-Leiden Survey. It was discovered in November...
It's nice to see this was in the just issued DOU, it was the oldest single opposition Jupiter trojan by a long way, now the oldest are a number of 1995...
Ignacio, Thanks for alerting the comet community. I agree that during the next few weeks it is worth monitoring this asteroid (4105) for activity. My ...
I already talk on this list about ambiguity in naming objects, maybe also about what is (at least in my opinion) a problem: the existence of two distinct...
