charset=us-ascii Date: Wed, 22 Mar 2006 10:59:41 -0800 Hello again- Dick Simpson asked me to update you on the status of the MGS egress occultation recordings. We still observe sidelobes at egress due to the HGA rewind in some of the occultation data, but there are periods when the sidelobes are absent for days at a time. I will include a summary of the past three weeks below. I have examined all data through occultation 31433e (2006/080-13:24:00) at DSS 54. Please let me know if you have any questions.

You will occassionally see the sidelobes, I expect that. There is still one momentum management position which if used will not allow the antenna enough time to get back in position before egress. We should be using this position infrequently, and your data seems to support that. Now that occultations are getting longer again, this shuld fix itself. By April 26th even this 3rd momentum control position will have enough time. So just hang on and all will be well. I'm glad to hear you are still getting most orbits. It will start improving from here. Please keep me informed, and certainly let me know if it gets worse. Dale
