+<h4>Why we ask for the time the GPS was recorded</h4>
+<p>Because ionospheric disturbance happens on a scale of an hour or so, every few hours,
+and is local to an area about ~50km in size. If we continuously record the GPS position
+of the potato hut during the expo then we will know if the GPS 
+position of this cave entrancce was recorded during one of these "bad" periods.</p>
+<p>Go back and re-record the GPS positon the next day at the exact same point and put that data in the logbook.</p>
