Description

On 1 Sep 2017 at 12h UT 3122 Florence passed at 0.047 AU (7.1 million km) from Earth. I took 120 images of 60s exposure and combined these. The long trail is the asteroid tracking south to north. The other short more or less horizontal trails are geostationary satellites (declination of the field is -03°).
