The specular track began at about (78N, 101E), moved close to the north pole (87.7N, 177E), and then ended at (64N, 258E). The quick-look processing does not show the intricate structure visible in echoes collected last summer from the north pole; but the geometry is somewhat different and more detail may come out with additional processing. Anomalies --------- As has been true since 2009/226, the S-LCP channel is very noisy (an equivalent system temperature of about 100K where 25K is expected). The NOPE is investigating. The S-RCP noise diode was not turned off at the end of MINICAL1. The NMC log shows no 'disable' command, as would have been expected shortly after 11:24. As a result excess noise power was present throughout the surface observations. The noise diode was turned off at the expected time during MINICAL2. There is interference on the X-RCP channel from about 11:22 to about 11:32. Fortunately, this is just after the X-RCP MINICAL1. By carefully selecting the calibration window, it should be possible to salvage the calibration with negligible impact on science. Source of the interference is not known. There appeared to be problems switching out the ambient load during the S-LCP pre- and post-cals. Queries for 100 kHz data are 90 percent complete. The missing data are from the S-LCP channel and have not yet been successfully transferred from DSS 14 to JPL. When that set of files is complete, we will issue a second report.
