It appears that Kevin's 99212/13706B and 99215/13712B unknowns are one and the same object. The tracks of these objects are on the same part of the sky and have similar directions and angular motions. Since the observations are separated by about 6 days there are several solutions that fit these observations. They differ by the number of revolutions the object has had between them. Below are a set of search elements ranging from 15 revolutions (elset 79015) to 21 revolutions (elset 79021). Kevin, the best strategy to recover the object is to look at the same part of the sky at the following times: August 2nd, 03:52UT; elsets 79015, 79018, 79021 should be visible August 3rd, 03:47UT; elsets 79016, 79018, 79020 should be visible August 4th, 03:42UT; elsets 79015, 79018, 79021 should be visible August 5th, 03:37UT; elset 79018 should be visible August 6th, 03:32UT; all elsets should be visible. If you see it and can track it for a significant part of the orbit it should help distinguish which of the search elsets is the best fit.
