Map of Phoenix area from Occult Watcher. The green line is the predicted central line, while the blue ones are the predicted northern and southern limits. The red lines are the limits in case of a very possible shift of the path with a one-sigma error to the north or south. The lighter red line at the top is the northern limit in the unlikely case of a three-sigma shift of the path to the north. The black lines with telescope symbols show current coverage of the path; we need more! The line passing through Gilbert is for an observer in New Mexico, so his telescope symbol is off the map. The Dunhams will be adding lines for their remote stations soon - they don't want to duplicate your observation.
