Daily Record of Facility Operation - Anchorage ARTCC - November 17, 1986

This document is a Daily Record of Facility Operation for the Anchorage ARTCC (ZAN) dated November 17, 1986. The log details routine air traffic control operations, including the management of volcanic activity reports from Mt. Pavlof and the issuance of related NOTAMs. A significant portion of the log concerns an incident involving flight JL1628 (a Boeing 747). At 0221 GMT, the flight reported traffic at its altitude (FL350) described as having a white and yellow strobe. The log notes that the unknown target was 'apparently pacing' the aircraft. Both ZAN and the EDF ROCC (Regional Operational Control Center) maintained intermittent non-radar contact with the target. By 0254 GMT, JL1628 lost visual contact, and by 0257 GMT, the EDF ROCC lost radar contact with the target, which was positioned at the aircraft's 7 o'clock position. Subsequent entries indicate that the incident was briefed to the Washington D.C. Regional Operations Center (WASHDC ROC) and that there was a request for EARTS data reduction regarding the JL1628 incident. The document also includes a personnel log for the facility.
