Aris Apsiotes was sent to investigate and discovered a hole in the SCIGN tall radome caused by repeated blows from a brick-wielding vandal. Steps will be taken over the next several weeks to isolate the true source of the displacement (broken radome, broken antenna or deformed monument). We'll keep you informed about this situation, but use data from this site with caution until then. Thanks for your attention, John Galetzka Network Coordinator Southern California Integrated GPS Network (SCIGN) USGS-Pasadena galetzka@gps.caltech.edu 626-583-7230
