Murison continued working on obtaining orbital parameter errors of an orbiting body from incomplete state vector observations taken from an orbiting platform (i.e., SSA), concentrating mainly on updating the technical memorandum with recent results, as well as putting together an executive summary of results to date.

Murison resumed work on the orbit-orbit distance problem, adding to the draft of the paper intended for the Astronomical Journal. (It turns out this and the SSA work share several useful relations.)

Starting from the Maxwell equations, Murison is deriving the dependence of refraction in the Earth's atmosphere on temperature, pressure, humidity (TPH), as well as crude chemical makeup. This is in support of the USNO dFTS, which has obtained some very precise measurements of TPH which may lead to refinement of the parameters via nonlinear least squares. (The standard TPH relations were "derived" by engineers and, hence, are decidedly inelegant and physically unenlightening.)

Murison refereed a paper for the Astronomical Journal.
