HAARP campaign update: Luxembourg Broadcast & Artificial Aurora

Many thanks to Chris Fallen (KL3WX), Assistant research professor in the University of Alaska Fairbanks Geophysical – Space Physics group , who shares the following update from the High Frequency Active Auroral Research Program (HAARP):

Campaign time!

Experiments begin in the mid morning 19 February Alaska Standard Time (AKST) and continue intermittently through the evening each day through 22 February.

Luxembourg Broadcast

The first radio modification of the ionosphere occurred in the early 1930s and was an accidental consequence of the new and powerful Radio Luxembourg transmitter. In certain situations, listeners of other weaker broadcast radio stations found that they sometimes heard Radio Luxembourg programming even though it was transmitted on a completely different frequency. Scientists and engineers eventually concluded that signals from powerful Radio Luxembourg and less powerful stations were being mixed in space, that is, through ionosphere modification.

HAARP will transmit a sequence of tones and music using amplitude modulation (AM) on two different radio frequencies (2.7 MHz and 3.3 MHz) in a sort of reproduction of this so-called Luxembourg Effect. If conditions are sufficient and you tune-in to one frequency or the other, you will hear tones and music from both frequencies. The tones and music have been specifically composed to take advantage of the Luxembourg effect.

The Luxembourg broadcast will begin as early as 6 p.m. on 19 and 20 February Alaska Standard Time (AKST) and conclude by 6:40 p.m. In Coordinate Universal Time (UTC), the broadcasts will begin as early as 03:00 on 20 and 21 February and conclude by 03:40. Tune in to 2.7 MHz or 3.3 MHz (2700 KHz or 3300 KHz), or both! The program is approximately 10 minutes in duration and will repeat until 6:40 p.m. AKST or 03:40 UTC.

Artificial Aurora

Aurora photographers in Alaska, Yukon Territory, and northwest British Columbia have a chance to photograph artificial aurora created with HAARP, starting immediately after the Luxembourg Broadcast and continuing until the ionosphere critical frequency over Gakona drops below about 2.7 MHz.

Radio listeners can still tune-in to these operations, but the transmissions are slightly more complex in order to test a scientific hypothesis. Also, at least in these initial experiments, the broadcast will only sound like a silent carrier wave, as if a radio DJ fell asleep and neglected to change the record (or now, more likely, the digital file). The specific transmission sequence is as follows:

MAIN: Repeat the following 480 second sequence if foF2 > 2.80 MHz

90 seconds : 2.80 MHz
30 seconds : OFF
90 seconds : 2.80 MHz, O mode, CW modulation, MZ direction
30 seconds : OFF
90 seconds : 2.82 MHz, O mode, CW modulation, MZ direction
30 seconds : OFF
90 seconds : 2.84 MHz, O mode, CW modulation, MZ direction
30 seconds : OFF

BACKUP: Repeat the following 240 second sequence if foF2 < 2.80 MHz

90 seconds : 2.75 MHz
30 seconds : OFF
90 seconds : 2.75 MHz
30 seconds : OFF

Thank you, Chris.

Chris tells me that his campaigns are “strenuous chair-and-keyboard marathons” where, at times, he drives a mile or so to adjust cameras and drives back to the operations center to make adjustments there–the process being repeated many times over. I can only imagine how challenging it must be working with a site so vast.

Note that we have given Chris Fallen an account on the SWLing Post so he can directly post details about HAARP campaigns and research prior to and after events, when his time allows.

    Correction!

    The Luxembourg broadcast will now be at 2.8 MHz and 3.3 MHz, still starting between 20 Feb 03.00 and 03.30 UT and concluding by 03.40 UT.

    Thanks for posting the update to SWLing, Thomas!

    Hard to pick something up tonight – STANAG stations, Italian pirates and russian dunnowhat in USB and a local storm were not exactly helping the apparently even more deteriorated condx towards the US, which were weak all day. SFI is climbing but condx are getting worse. It’s about time you guys learn how to change that, while you’re at it I want 25C and sunshine from March through November, and maybe if you put a bit more coal on you could make the ladies around here think that I’m the best catch in town. Thanks in advance! 🙂

    Looks like you’re having a blast tonight! 🙂 I could pick up your airglow beam fine again, but (just like the other nights) nothing of the preceding experiments. I also checked the Twente and some German webSDRs and so far only one of them located 100km S from here picked the carriers up as well.

    I know this is not relevant for your experiments but I made some crude screen captures (animated GIFs) and audio recordings (of the carrier in USB tuned 1kHz lower). If you’re interested I could email you some of that. Maybe just so you can say with good conscience “the signals were even heard in “.
