[IGSSTATION-7803] - 2019-11-13 (15/11/2019)
The USGS has recently replaced the receiver and antenna at the Long Beach (LBCH) IGS station. An updated site log has been submitted to the IGSCB. The data for November 8-11 (DOY 312-315) will be replaced due to incorrect metadata. This station is operated and maintained by the USGS Pasadena office.

[IGSSTATION-7484] - 2018-12-09 (11/12/2018)
We were just notified by the USGS that the data provided by Long Beach, CA (LBCH) station was in fact for the wrong station since Sept 1th. We need to ask all IGS data centers to remove LBCH data for 09/01/18 - 12/05/18 ( days 244-339) from their archives. The LBCH data files for days 340-341 should be correct. The USGS will need to manually download the LBCH data to recover it for this period.
