The cover image of MAPS 37-5, 2002, May, does show
the trajectory projected onto a Landsat 7 image but no
details are given.

With regard to its entry angle, Brown et al. write on page 673:

"From our best estimate of the initial mass of the
Tagish Lake object of ca. 56 tonnes, its initial
velocity (15.8 km/s), its known angle of entry (17.8°) ..."

Lake fireball using seismic, satellite and infrasound records
(MAPS 37-5, 2002 May, pp. 661-675).


Best regards,
