We had 13 days with no known <1 LD flyby after 7 asteroids flew past us within 1 lunar distance from January 15 – 24. The silence was broken yesterday when 2 new close flybys were discovered.

The next known <1 LD flyby will take place at 09:47 UTC on February 9 when asteroid 2018 CB zips past us at a distance of 0.17 LD / 0.00043 AU.
