Is anyone else monitoring/recording WWVB? If so, can you please check and see if you were receiving good data from 06/01/2023 16:24:00 to 16:49:00 UTC? My 100 Hz recording is showing a flat line starting around 16:24:14, then noise starting at about 16:26:08, and back to solid copy at 16:48:51. The signal looks really clean both before and after this time period, which doesn't fit with atmospheric disturbances. Same timeframe yesterday was clean, too. Here's a (472 kB) text dump of the hour in question: https://www.n5tnl.com/time/wwvb/wwvb_weird.txt thanks! newell N5TNL

This plot taken in Boulder shows a clear drop-out today between the times you mentioned: https://tf.nist.gov/tf-cgi/wwvbgraph_e.cgi?6009601001 There is an outage page that doesn't (yet) indicate any anomaly, but maybe the page just hasn't been updated yet: https://www.nist.gov/pml/time-and-frequency-division/time-distribution/radio-station-wwvb/wwvb-station-outages 73 de John, KD2BD
