Band is generous now. Had a QSO (confirmed) with YT3PL, 5937 miles away in
Serbia recently, and all that with the Hustler vertical on my roof.

Sunday November 1-3
To: PVRC <p...@mailman.qth.net>
Some of the best HF and 6 meter F2 propagation of Solar Cycle 24 is likely to
continue for the next week
Propagation crossing polar and auroral regions is likely to be mostly normal
through at least late Sunday
Propagation crossing low and mid latitudes is likely to be normal through at
least late Sunday.

This forecast derived from today's NOAA/SWPC web pages and 15 other online
sources (the URLs at the end of this forecast) is published five days a week
(M-F) in The Daily DX.
All days and times in this forecast are in UTC (Zulu) time.
More frequent, longer duration and more geographically widespread global 6
meter F2 propagation is likely through this weekend and continuing through next
week and again during late November if solar flux values persist well above 200
for several days. 6 meter Trans-Equatorial F2 Propagation (TEP) is likely
almost every day and long path propagation is possible from the southern tier
of U.S. states during the next week. More northerly mid-latitude locations need
a less reliable additional above-the-MUF mid-latitude F2 hop or an unreliable
and infrequent additional sporadic-E hop. 6 meter sporadic-E propagation beyond
2200 km is extremely unlikely until December.

The 2300Z Penticton 10.7 cm observed solar flux index was 297 and is likely to
remain about the same through at least Sunday.

SILSO’s latest Estimated International Sunspot Number was 210 and is likely to
remain about the same through at least Sunday.

The visible solar disk has two growing large active regions, two growing medium
active regions, one stable medium active region and two decaying medium active
regions. There are 77 sunspots on the visible disk with a total sunspot area is
2320 micro solar hemispheres (about 14 times the surface area of the Earth).

Solar wind speed is likely to remain above 400 km/second through Sunday.
Mostly quiet geomagnetic conditions are likely through at least late Sunday.

Frequent M-class solar flares are expected to cause brief periods of minor
blackouts of propagation paths crossing the sunlit side of the Earth through
Sunday. There is a chance that X-class solar flares may cause an hour or more
of radio blackouts of propagation paths crossing the sunlit side of the Earth
through Sunday.

The ongoing S1 minor solar energetic particle radiation storm and associated
minor polar cap absorption is likely to end during Friday.
www.swpc.noaa.gov/phenomena/solar-radiation-storm
160 and 80 meter propagation from North America to VK/ZL and the South Pacific
is likely to be normal through Sunday. 160 and 80 meter long distance
propagation in the northern hemisphere is always mildly to moderately degraded
through September by E region blanketing of low angle F2 propagation until at
least several hours after sunset.
40 meter short path propagation from North America to the Middle East and south
Asia after 2200Z is likely to be mostly normal through Sunday. Short path
propagation between North America and east Asia after about 0800Z is likely to
be mostly normal through Sunday.
30 meter propagation crossing the auroral ovals and polar regions is likely to
be mostly normal through Sunday. Daytime 30 meter long distance propagation is
always mildly to moderately degraded within several hours of local noon by
E-region blanketing of low angle long distance F2 propagation.
20 meter propagation crossing the auroral ovals and polar regions is likely to
be mostly normal through Sunday. 20 meter propagation beyond 2200 km in the low
latitude northern hemisphere is likely to be mildly degraded during midday
hours through at least October due to E-region blanketing of low angle F2
propagation.
17 and 15 meter propagation crossing the auroral ovals and polar regions is
likely to be mostly normal through Sunday. 17 and 15 meter long path
propagation from North America to southeast and east Asia from about 1100Z to
1400Z is likely to be mostly normal through Sunday.
12 and 10 meter propagation crossing the auroral ovals and polar regions is
likely to be mostly normal through Sunday. 12 and 10 meter long path
propagation from North America to southeast and east Asia from about 1100Z to
1400Z is likely to be mostly normal through Sunday.
There is a chance of above-the-MUF 6 meter F2 propagation over Africa from the
more easterly US states to the Indian Ocean, equatorial and southern Africa
(e.g., 3B8. 3B9, 7Q, D2, FR, V5, ZD7, ZD9 and ZS) from about 1400-1700Z during
early and late November. Trans-equatorial F2 propagation (TEP) is likely from
the southern tier of U.S. states to South America from about 2000-0200Z or
later. There is a slight chance of above-the-MUF oblique-TEP F2 propagation
from the southern tier of U.S. states to the south Pacific (e.g., 3D2, 5W, E5,
FK, FO, VK4, VP6 and ZL) from about 1900-0300Z. There is a chance that more
northerly U.S. stations may couple into TEP and oblique-TEP via brief intervals
of above-the-MUF mid-latitude F2 propagation. There is a chance of TEP
propagation from about 2000-0200Z during the initial phase of strong to severe
geomagnetic storms then degrading several hours after initial enhancement. See
K6MIO’s excellent article on 6 meter TEP, oblique-TEP, TEP-related and
mid-latitude sporadic-E linking to TEP beginning on page 9 at:
http://www.oh3ac.fi/QEX-2016-11.pdf
Sustained southward orientation (-Bz) of the north-south component of the
interplanetary magnetic field (IMF) plays a crucial but unpredictable role in
triggering all geomagnetic storms. Brief minor to moderate geomagnetic
storms may be gradually triggered when the IMF is sustained in a southward
orientation (-Bz) with IMF field strength of about 5 nanoteslas or more for at
least a few hours coincident with the influence of a geoeffective coronal hole
high speed stream or CME. More frequent, longer duration, minor to severe
geomagnetic storms may be triggered suddenly and unpredictably when the IMF is
sustained in a southward orientation (-Bz) with IMF field strength of about 5
nanoteslas or more for a period of several hours or more coincident with the
influence of a geoeffective CME and solar wind speed of about 500 km/second or
more.
Mid-latitude northern hemisphere sunrise is 40 minutes later and sunset is 58
minutes earlier than it was on September 22nd. Sunrise is about two hours
earlier and sunset is about two hours later at the altitude of the refracting
F2 region. Sunrise is about one hour earlier, and sunset is about one hour
later at the altitude of the daytime absorbing D region.
