The reason in unknown. It looks like the track got changed. The earlier SOE which I used had BOT at 2155, and we got the first measurement. The later SOE, however, shows BOT at 01:40, after the second measurement. The carrier level was very low at egress in the occultation 32236e recording at DSS 43 (2006/146-05:26:00). This occultation was recorded successfully at DSS 24. There was a DR (#C105042). Description Unable to lock receivers and telemetry when antenna was in autocollimator mode. Corrective Action Engineering support found the antenna's azimuth drive points were oscillating. This was affecting the HA of the ME (HA display oscillating). Some test points had not been grounded properly after a periodoc maintenance period. The DR covers times 05:28 - 05:38. -Danny -------------------------------------------------------------------------- Return-Path: Received: from mx3.stanford.edu (mx3.Stanford.EDU [171.67.20.23]) by pobox02.stanford.edu (Cyrus v2.2.12) with LMTPA; Wed, 31 May 2006 14:13:09 -0700 X-Sieve: CMU Sieve 2.2 Received: by mx3.stanford.edu (Postfix) id 3A7BA4BE7F; Wed, 31 May 2006 14:13:09 -0700 (PDT) Delivered-To: jtwicken@stanford.edu Received: from mx3.stanford.edu (localhost.localdomain [127.0.0.1]) by localhost (Postfix) with SMTP id 2F23A4BE64 for ; Wed, 31 May 2006 14:13:09 -0700 (PDT) Received: from nmta1.jpl.nasa.gov (nmta1.jpl.nasa.gov [137.78.160.214]) by mx3.stanford.edu (Postfix) with ESMTP id E4D504BE7F for ; Wed, 31 May 2006 14:13:08 -0700 (PDT) Received: from xmta2.jpl.nasa.gov (xmta2.jpl.nasa.gov [137.78.160.56]) by nmta1.jpl.nasa.gov (Switch-3.1.8/Switch-3.1.7) with ESMTP id k4VLD8DF026179 for ; Wed, 31 May 2006 14:13:08 -0700 Received: from jpl.nasa.gov (eis-msg-065.jpl.nasa.gov [137.78.160.102]) by xmta2.jpl.nasa.gov (Switch-3.1.8/Switch-3.1.7) with ESMTP id k4VLD7eW003051 for ; Wed, 31 May 2006 14:13:07 -0700 Received: from [137.78.160.72] (Forwarded-For: [137.78.78.85]) by mailhost4.jpl.nasa.gov (mshttpd); Wed, 31 May 2006 14:13:07 -0700 From: Daniel S Kahan To: Joe Twicken Message-ID: <37c9313768de.3768de37c931@jpl.nasa.gov> Date: Wed, 31 May 2006 14:13:07 -0700 X-Mailer: iPlanet Messenger Express 5.2 HotFix 1.25 (built Mar 3 2004) MIME-Version: 1.0 Content-Language: en Subject: Re: MGS RST Rpt HEAG150A.TXT X-Accept-Language: en Priority: normal Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: 7bit X-Source-IP: eis-msg-065.jpl.nasa.gov [137.78.160.102] X-Source-Sender: Daniel.S.Kahan-121461@jpl.nasa.gov X-AUTH: Internal IP Joe, After further investigation I discovered that we got the earlier occultation by pure luck.
