Hi Bill,

In the Doppler radar data from Green Bay, WI, (KGRB) in the 7th cut
angle
(1.85 degrees) of a scan that began at 01:51:26 UT, there is a
moderately
strong hit at 47.348N, 84.470W, alt. 25.4 km. This seems to be extremely
close to being online with your two data points below. Unfortunately, it
is also only about 10 km east of Lake Superior.  --Rob

This event occurred on June 14 at 9:51:30 PM EDT (June 15 01:51:30 UTC),
lasted approximately 10 seconds, and was widely seen across the northern
United States and southern Canada. Analyses of 5 all sky videos from the
Southern Ontario Meteor Network were performed by NASA Meteoroid
Environment Office and Western University's Meteor Physics Group,
yielding the following trajectory: 

Start point: 79.573 W, 44.552 N at an altitude of 101.4 km Last
detection: 82.317 W, 46.142 N at an altitude of 61.5 km Average speed:
28.3 +/- 0.5 km/s 

Radiant coordinates of RA 265.2, Dec -19.9 are within the anti-helion
sporadic source. The meteor was moving too fast and was too high to
produce meteorites on the ground. Orbit shows no resemblance to that of
2012 LZ1, which made a close approach to Earth on June 14.
