Heads up for pilots flying in the Copper River Basin—the High Frequency Active Auroral Research Program (HAARP) is conducting a research campaign this month. HAARP is operated by the Geophysical Institute at the University of Alaska Fairbanks, to support auroral and upper-atmospheric research. The FAA will again establish a TFR over the facility, 16 nautical miles north east of the Gulkana Airport (GKN), along the Tok Cutoff, when the facility is running. The campaign starts with a test day on April 3rd, with the bulk of the campaign taking place from April 6-14. Check for NOTAMs with specific times the TFR will be in effect.
This campaign supports a number of research projects. Operating times fluctuate due to the constantly changing nature of the ionosphere. While they won’t be operating outside the times listed in the NOTAM, there may be gaps within those time windows. As part of being a good neighbor, the HAARP Project is providing a local phone number (907-822-5497) pilots may use for more detailed information, and a new VHF radio frequency, 123.3 MHz, to call airborne when flying in the vicinity of the facility. For more background on this program see this previous post. AOPA has requested that the HAARP facility be charted, to increase situational awareness of the facility.
