Looking East  Dec 14 23:30pm - the Bulls eye mark the Gem radiant - a short distance from mag +1.58 star Castor-Pollux pair.  White streaks simulated the Geminids appearance. Grids are elevation and azimuth in degrees.
1) Limiting Magnitude Determination ( how dark your sky is) a) Using Chart 4a  - simply count the no. of stars visible bounded in the region ( pick any of the #4 ,#17 ,#8 ,#22)
b) Obtain the corresponding LM from the conversion table 
2) Tips  - head for a darker site in neighboring  country 
 - watch a day earlier - after mid night Friday - Sat Dawn, just in case Sat/Sunday weather turns bad..
3) Things you could do  - Point a camcorder - say centre on Orion on tripod.  Select the lowest shutter and LP recording.
