Roll up, Roll up!
Tonight only!!
Antenna will have a modified camera flash strobe on top of it, should flash from dark until about 1am or so.
One flash every 5-8 seconds.

If you live out west, get out your binoculars and take a peek.
Approximate position from west (te atatu ish anyway).
Take the distance between the skytower and the asb tower (tall building with lit up yellow ASB on top).
Go to the right of the ASB building for about 4 times this distance.
You should be looking at the newcall building. antenna is to the bottom right of the newcall building.

LOOK FOR THE FLASH and report back......

Cheers
