State Northridge) effective Julian day 226/1998. Data will be downloaded nightly at the USGS, then forwarded to Scripps for archiving. The Z-XII is presently connected to the choke-ring antenna that had been in use with the TurboRogue receiver. The Z-XII receiver appears to be tracking well. The Z-XII receiver at HOLC (Holcomb Ridge) has been replaced by a SCIGN issue Z-XII also effective day 226/1998. The removed receiv- er presently refuses to release data for days 223, 225 and 226. We will attempt to recover this data at the USGS lab. Lightning strikes which destroyed a surge suppressor at the site may be to blame for this failure. Thank you. ******************************************************************* Jeff Behr SCIGN Operations Center TEL: (626) 583-7816 US Geological Survey FAX: (626) 583-7827 525 S.
