Edgar's result is
truly remarkable: It's fascinating to see the rainbow colour change
(yellow-green-blue, and back) during the solar flare, showing the phase advance
due to the transient depression of the waveguide ceiling. Looking more
closely at his image, at the peak of the x-ray burst there
are also short patches from two Saudi Arabian stations, Afif (faint
blue) and Salwa (yellow), pushing out that daytime record quite a bit
more! Note that background
noise also went up, likely due to propagation from distant lightning
activity opening up. It just appears that this
solar event was literally heaven-sent, occuring at the perfect time to
vertically illuminate the path across the Indian Ocean.
From here, I have been monitoring Loran-C for many
years now, but my daytime detections have never extended much beyond the
former Canadian Loran stations at about 5 Mm. Edgar's result once more
shows the outstanding quality of his receive setup and site, combined with
the absence of clutter from nearby Loran stations, and a well-lit equatorial
path to his southerly location.

Subject: Loran C - reception distance
The long distance record for the
reception of Loran C stations was achieved again, at Moonah, Tasmania,
Signals from Anthorn 17501 km, Lessay 17521 km, and Eide 17271 km
were received overnight.
https://dl.dropboxusercontent.com/u/101251787/Loran%20C/Loran%20C.htmlSignals from the Gesashi were received over a distance of 7937
km during daylight hours.
Also, due to enhanced propagation from an X-ray
flare signals were detected from Hexian 8248km, Raoping 8003km,
8684 km, Rongcheng 9205 km, Kwang Ju 8880 km, Gesashi 7937 km and Pohang 8940 km
during daylight hours.
A big thank you to Markus Vester DF6NM for his
software, encouragement and mentoring to achieve these results.
