Varvara's Travels April 22-29, 2012
We continue to get individual messages, so we know the tag is still attached, but multiple messages within a single orbit are required to get a good location. There were two B class locations on 24 April during this week, which were roughly 5 minutes apart, but were geographically quite far apart. They were separated by the distance across the Zhemchug Canyon on a SE/NW axis. These were the first candidate locations since 4/20, so the speeds are quite similar (5.16 vs. 6.2 km/hr). Thus, both these locations pass our speed criteria  and there is not a firm basis upon which to decide which one is correct. Both lay along the ice edge and also the upper slope edge.
