## 0915 ENDED SESSION
(*) - Meteors marked by asterisks have additional data under Remarks
--------------------------------------------------------------------
--------------------------------------------------------------------
VELOCITY SCALE:
0 = Stationary
1 = Very Slow
2 = Slow
3 = Medium
4 = Fast
5 = Very Fast

---------------------------------------------------------------------
REMARKS: Seeing throughout session was poor to very poor.
Dead time of 15 seconds was deducted per recorded meteor.
Meteor #29 travelled 35 degrees in 4 seconds.
Meteor #44 was interesting as it was noted very close to the radiant,
(one possible explanation for it's apparent velocity of only 3.5),
and is also notable because it was quite dim. With a fast shower
such as the LEOs, this observer's experience does seem to indicate
that dimmer meteors are better observed when foreshortened.
Temp at beginning of session: 15o F Humidity: 45%
Temp at end of session: 5o F Humidity: 20%
