Dave, good to hear from you again and thanks for the heads up. Now I know where that cloud is coming from
. The path goes straight over me so the travel distance is nil. The weather forecast is just so so. Too cloudy to be optimistic but too clear to write off. So you've just changed my plans for Saturday.
I can use a 'beeper box' but it will only be synced to a GPS by eye/ear. At least the duration will be passably accurate. [Of course near the edge of the path even presence/absence is a result.] There are plenty of astronomers under or near the path so lets hope quite a few jump on board!
