Here is the method to the madness:
I place a marker, centered on the storm and upload the image. I don't move the marker for several hours so I can see the storm's relative movement as it moves away from the marker.
After a fews hours, I reset the marker to get a new fix.
Note, you need to click on the thumbnail to open the image. Once it's opened, you may need to click on it AGAIN (and/or maximize your window) to see it fullsize. You should be able to read the time stamp (right column) clearly. All times are CDT.
Allright wobble watchers, go nuts
Almost stationary now...
