I'm the developer of that WebSDR, and I was already planning to use it to
make some raw signal recordings on New Year's eve.
This is not just to capture the LORAN shutdown, but also the shutdown of a
bunch of medium-wave broadcast stations (from France, Germany and Luxemburg).

My current plan is to record the 0 - 1800 kHz spectrum (output of the ADC,
but low-pass filtered and downsampled) for at least a couple of minutes
(but possibly more) around "interesting" times such as midnight local time
and midnight UTC.
