Another chance for European VLF observers could be the long-path component =
from NWC Australia, 19.8 kHz. A transient phase change over America could p=
roduce a dent in the ripple pattern which comes from the superposition of l=
ong and short path. NWC is now shown in a strip at the bottom of the wideba=
nd spectrograms on DL0AO and DF6NM grabbers:

Unofficial EclipseMob update:

Dixon will warm up starting ~ 06:45 Pacific Time, ramping ERP to ~ 1-2 kW a=
t 55.500 kHz and ~ 3-4 kW at 135.950 kHz by 07:30 Pacific Time, broadcastin=
g MSK 101010..., until one or two hours after East Coast totality.
Dixon frequency may wander slightly.
Comparing Dixon signal to WWVB signal could be interesting.=20

Dixon 55.500 kHz signal field strength could be ~ 40 fT in Forest, VA

A 137 kHz signal from VO1NA, or Warren, or an LF or VLF signal from W4DEX m=
ight be captured and saved by a record number of receivers, and put to good=
 use.=20

There is a slight chance to observe effects via the propagation paths from =
NAU, NAA or NML to Europe. Especially NAU looks promising since the C-flare=
 from 2017-07-15, ~1940 utc, could be observed quite well here.

Good luck to all EclipseMob members!
