Location:  Alert (Ellesmere Island), Nunavut, Canada
Agency:    Natural Resources Canada (NRCan), Geodetic Survey Division

Data was recovered for station ALRT from D232 until D252, except for 
a 3 day gap between D236 & D239. 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.
