Everything went well; however, the subreflector was not fixed until about 04:48:00. There was an antenna problem right before the occultation, but it was corrected in time.

There was a notation that there would be possible RFI at Goldstone. This usually means that Goldstone Solar System Radar is being used. Please let me know if you see anything.

There was a notation that >there would be possible RFI at Goldstone. This usually means that >Goldstone Solar System Radar is being used. Please let me know if you >see anything. This occurs over Goldstone for the next 5 days. Carrier to noise level from the DSS 15 data was 51.2 dB, tied for second highest since we began occultations in January. There are some low level oscillations in carrier amplitude (a few tenths dB with periods ~30 sec) prior to occultation. If GSSR was running during this occultation, it's not apparent at the quick-look level. ----------------------------------------------------------------------- From hinson@nimbus.Stanford.EDU Mon Mar 2 10:23:29 1998 Received: from nimbus.Stanford.EDU (nimbus.Stanford.EDU [36.10.0.96]) by magellan.Stanford.EDU (8.8.5/8.8.3) with ESMTP id KAA20258 for ; Mon, 2 Mar 1998 10:23:29 -0800 (PST) Received: (from hinson@localhost) by nimbus.Stanford.EDU (8.8.4/8.8.3) id KAA01778; Mon, 2 Mar 1998 10:23:24 -0800 (PST) Date: Mon, 2 Mar 1998 10:23:24 -0800 (PST) From: Dave Hinson Message-Id: <199803021823.KAA01778@nimbus.Stanford.EDU> To: joe@neptune.Stanford.EDU, rsimpson@magellan.Stanford.EDU Subject: occultation #47 X-Sun-Charset: US-ASCII Content-Length: 279 Status: O An ionosphere suddenly appeared in the data from occultation #47. This is the first, clear indication of an ionosphere since the orbit insertion occultation. Solar zenith angle has been decreasing steadily since we began occultations in late January. It's now at 95 deg.
