I don't recall any others where the occultation was missed or the baseline was substantially impacted. It is just odd to see recordings that are less than full length. For example in this report there is also one that stops at 2005/343-04:01:25 (35 seconds early), one that starts at 2005/347-16:26:08 (8 seconds late) and one that starts at 2005/347-18:24:03 (3 seconds late). -------------------------------------------------------------------------- To: jtwicken@stanford.edu Subject: Re: MGS RST Rpt HEA5348A.TXT Cc: rfj@stanford.edu >I don't recall any others where the occultation was missed ... OK. Then that's probably good enough. JPL has been suffering from some serious connectivity problems during the past week. One hypothesis is that Danny requests normal times but (for unknown reasons) the message doesn't get to the station with enough time and the recording begins late. We see 1 second delays a lot; but 8 or 25 seconds seems extreme. During the MEX bistatic radar last Friday night, we lost the connections between JPL and 4 RSR's over about an hour. Fortunately, the RSRs were running (and the experiment was mostly over); but I left Danny and Gene Goltz scratching their heads about how to kill the jobs without driving out to the station themselves. Two days later, the connection had been restored and the RSR's were under control; but Gene said he still didn't know how that had been done. Today one of the main routers at JPL was rebooted in hopes that would cure some of the remaining problems. I happened to be logged in to rsops2 looking for those records beyond 31 when the reboot occurred. I suspect we're seeing some of the outer symptoms of this larger problem. Except in cases where we get next to nothing, it's probably better not to rock the boat.
