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.
Best 73,

The long distance record for the reception of Loran C stations was achieved again, at Moonah, Tasmania, QE37pd.

Signals from Anthorn 17501 km, Lessay 17521 km, and Eide 17271 km were received overnight.

Signals 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,
Xuancheng 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.

Regards, Edgar
Moonah, Tasmania.
