SGP/SIRS/E6 - Datalogger failure

During this time period all SIRS instruments experienced intermittent data dropouts.  
Starting 6/9/2010 the up_long hemisp and up_short_hemisp instruments dropped out.  On 6/10 
approximately 1800GMT the down_long hemisp instrument and down_short_hemisp instruments 
started dropping out.  In addition, after this time all values from the logger became 
intermittent.  On 06/12/2010 site ops replaced the logger and wiring panel at approx. 1500 GMT. 
 All systems were returned to service approximately 1630GMT.

Data are questionable and not recoverable.
