The data was collected using a replacement receiver of the same type as the original (Ashtech Micro-Z). The original Micro-Z has been back on-line since D239 (see IGSSTATION-3365). An updated site log has been submitted to the IGS CB. A copy can also be found at In total there were approximately 26.5 days of data lost between the following periods: 2009-07-28 (D209) 19:33:30Z --> 2009-08-20 (D232) 18:23:30Z (23 days) 2009-08-24 (D236) 13:11:00Z --> 2009-08-27 (D239) 23:12:00Z (3.5 days) There were also a few shorter outages of few hours each between D232 & D236. We thank Mike Piraszewski for enduring an uncomfortable two day flight up to Alert aboard a Canadian Air Force Hercules transport, not to mention the -25 C temperatures. -- Mike Craymer, Ph.D. Geodetic Survey Division, Natural Resources Canada 615 Booth Street, Ottawa, Ontario K1A 0E9, Canada Tel 613-947-1829, Fax 613-992-6628, Cell 613-791-0157 Email Geodetic Survey Division NAREF
