METEOR DATA:
General notes:
- where degrees of train specified, duration was 1-1.5 seconds unless
otherwise specified.
- all colours white unless specified.
- "low" refers to very close to horizon.
- "near rad" refers to right at radiant.
- "short" refers to less than 1 degree long.
- showers observed were LEO, and NTA and STA until about 6.30 UT when
radiant positions for NTA and STA moved out of my field of view.
Weather notes:
- limiting magnitudes as noted.
- 9.00 UT - getting glare from Venus, glare up to about 20 degrees from horizon.
- 9.10 UT - sky degrading a bit, but LM unchanged.
- 9.50 UT - sky degrading, light cirrus moving in from west, LM change as
noted, glare from Venus up to about 20 degrees from horizon.
- 10.36 UT - about 20% cloud in my area.
- 10.48 UT - about 25% cloud in my area and light cirrus.
