REMARKS:
- recording time/meteor: 2 sec
- DCV is distance of meteor from centre of view
- LEN is length of meteor in degrees
- temperature about -5C (23F)
- calm night, but did have several helicopters fly over
comments on meteors:
- meteors #9, #15, #22 and #26 all bright, slow or average-to-slow, &
yellowish, traced back to approximately the 'kids' of Auriga or beyond,
called SPO due to ambiguity as to shower
- meteor #38, mag. 0 Leonid - breaks in train, looked neat!
- meteor #43, mag 3 Leonid - curved train, J-shaped at end
satellites seen:
- 9.10 UT, mag 3 satellite
- 10.00 UT, mag 4.5 satellite from bowl of Ursa Major (right to left)
towards bowl of Ursa Minor
- 10.55 UT, mag. 3 satellite from below Denebola to above Arcturus
