We have added an additional step of rechecking the next orbit's contacts for IBEX to make sure any recent data hasn't changed our approvals. After rechecking the next apogee contact scheduled for October 17th 22:30 on USHI01 (with the updates from the most recent orbit's tracking data/processing), it appears that it is right on the edge of the antenna null.  The antenna null is cleared starting at 1:40 on 18 Oct 2020 for the view period in question, which lasts from 17 Oct 2020 21:56:59.499 until 18 Oct 2020 07:47:21 on USHI01. If possible, you may want to move the contact to after 1:40 on the 18th. 

Thanks,

Kayton Lane
