During the test period, GLM signals may appear as short (5-10 minute) illuminations alternating between GOES-16 and GOES-17. This will be attempted periodically over the specified time frame until the test results are satisfied. The test is weather-dependent at both sites and there will be no testing during holidays and weekends.
