We are planning to observe as normal today starting with i18163. We did not observe R1846 or i18162 yesterday, so there will be no data from Kokee 20m for those sessions. mahalo, Chris Coughlin KPGO Station Manager - NASA/SCNS Peraton (808) 335-6495 ________________________________ From: IVS-ops on behalf of Coughlin, Christopher Sent: Monday, June 11, 2018 1:46 PM To: ivs-ops@lists.nasa.gov Cc: Ed Himwich; Lamb, Doug (Peraton) (US Person); Hilliard, Lawrence M.

The recool is taking much longer than normal due to faulty cold head or compressor. This has been an ongoing troubleshooting effort but has not been resolved as of yet. Kokee 20M will most likely not be able to observe any of today's R1 session. We are hoping to be back to normal dewar temperature levels for the INT1 session tomorrow at 18:30z. I will give updates on system and availability tomorrow morning. mahalo, Chris Coughlin KPGO Station Manager - NASA/SCNS Peraton (808) 335-6495 ________________________________ From: IVS-ops on behalf of Coughlin, Christopher Sent: Monday, June 11, 2018 6:56 AM To: ivs-ops@lists.nasa.gov Cc: Ed Himwich; Lamb, Doug (Peraton) (US Person); Hilliard, Lawrence M.
