I tried the times stated on one of the Twitter accounts and checked for any messages . They didn't
Tweet until it was over apparently.
Chris Fallen, an assistant research professor with the project, was Tweeting in near real time with reasonably up to the minute updates.

There was a loud S9 jammer type signal at 2700 , but I went to bed after the posted times passed.
A quick breakdown of the HAARP transmissions for early morning, 20 February, 2017:
~0110 to 0200 UTC, active on 4440 kHz with CW.
0207 to 0236 UTC, active on 3350 kHz. Burst sent every 30 seconds. Burst length is 4 seconds and consist of 15 short pulses at 5 pulses / second followed by one, one second long pulse. HAARP system was apparently in X mode during this time.
0239 to 0259 UTC, active on 2800 kHz. Same signal as 0207 to 0236 on 3350, 15 short pulses and one long pulse in a 4 second long burst sent every 30 seconds. Still apparently in X mode.
0300 to 0342 UTC, Using both 2800 and 3300 kHz at the same time in Luxembourg Transmission tests. This series involved different audio being sent in AM mode, sometimes tones, beeps, and music. This was a 9 minute and 30 second cycle repeated every 10 minutes, so there were 4 complete cycles during this time period, one starting 0300, the next 0312, next 0322, and the last starting at 0332 UTC
0343 to 0433 UTC, Sequencing 2800, 2820, and 2840 kHz, CW on each, Artificial Aurora test. Transmissions 90 seconds long on each freq, off air for 30 seconds, and then to the next in the cycle. Sequence was 2800 kHz in X mode, 2800 kHz in O mode, 2820 kHz in O mode, 2840 kHz in O mode, then back to start of sequence.
Keep in mind that when I use CW above I do not mean Morse code, rather I mean CW as defined by RF types not in communications, CW is Continuous Wave, and simply means an unmodulated carrier.
T!
