The Dateline DX Association and George, AA7JV have announced that

visit has been difficult to obtain: "we have worked very hard for the
past few years on this permission, and after demonstrating the success
of the RIB concept with remote operators from various locations in
2023, we have received a permit that allows 4 operators on the boat to
visit Jarvis with 6 stations on land". The on-site team - namely George
(AA7JV), Don (N1DG), Tomi (HA7RY) and Mike (KN4EEI) - will install 6
RIB (Radio In a Box) stations on the island, and will operate CW, SSB
and FT8 (F/H) on 160-6 meters. They will be accompanied by a team of
three USFWS biologists conducting science. In addition, 25 remote
operators from Asia, Europe and North America will be running CW and

Summary
For the 8 day period from Friday, July 19th through yesterday, July 26th.
The average solar flux was 183, down 43 points from the previous week,
with a weekly high of 207 on Saturday, July 20th, followed by
a low of 167 on July 25th.
The average sunspot count was 181, down by 63 from last week,
peaking at 269 on Friday, July 19th followed by a
weekly low of 160 on July 24th.
The Planetary K-index weekly average was 2.7 with a
maximum of 4.7 on Friday, July 26th, resulting
in generally quiet geomagnetic conditions.
Solar flare activity since July 20th has been very high with 18
major flares, the largest of which was an M 4.2 event on Saturday, July
27th.

Geomagnetic Storm Watch (G1)
NOAA forecasters say that G1-class
geomagnetic storms are possible today, July 27th, when a CME is
expected to graze Earth's magnetic field. A similar storm on July 25th
produced auroras in many northern-tier US states including Washington,
Wisconsin
and Maine.

A Propagation
Tutorial
The solar X-ray flux tracks solar activity and solar flares.
Solar
flux, which can vary from as low as 50 to as high as 300, influences
the level of ionization in the F2 region of the ionosphere, providing a
very good prediction of HF DX conditions. The higher the solar flux,
the better conditions will be for the higher HF frequencies and even 6
meters. However, the levels need to be maintained for some days to
allow ionization in the F2 layer to build up. A solar flux of 150
results in good HF band conditions, while levels of 200 and up can
provide great conditions.
Large X-ray flares on the sun can
increase the ionization of the D layer of the ionosphere (a lower
layer) on the sunlit side of the Earth, greatly attenuating or blocking
HF radio transmissions for up to a half hour. Solar flares often
produce Coronal Mass Ejections (CMEs) which, if Earth directed, can
lead to geomagnetic storms. Some large flares are also accompanied by
strong radio bursts that may interfere with other radio frequencies and
cause problems for satellite communication and radio navigation (GPS).
The
Planetary K-index is a measure of the magnitude of geomagnetic storms
and is an excellent indicator of disturbances in the Earth's magnetic
field. A level of 1 or 2 represents quiet geomagnetic conditions; a
reading of 3 or 4 may cause some propagation deterioration; 5 and 6 are
minor to moderate geomagnetic storms; and 7 to 9 are strong, severe,
and extreme storm conditions. Strong geomagnetic storms can trigger
Auroral displays and cause HF radio blackouts. Higher geomagnetic
activity also has the adverse effect of lowering maximum usable
frequencies, much like lower solar flux does.
For
best conditions, the solar flux should be above 150 for a few days with
the K index below 2. When these conditions are met, some good DX is
likely!
