SGP/RL/C1 - Low SNR

There was an abrupt decrease in SNR at approximately 20 UTC on 15 June that coincided with 
a thunderstorm. The signal remained abnormally low until about 19 UTC on 17 June when 
the window was cleaned by the on-site tech. The decreased signal may have been caused by 
the accumulation of bugs on the window that were scavenged out of the air by the thunderstorm.

Be aware that the sensitivity is lower during the period in question.
