Mid-latitude northern hemisphere sunrise is 69 minutes later and sunset is 78 minutes earlier than it was on September 23rd. Sunrise is about two hours earlier and sunset is about two hours later at the 300 km altitude of the F2 region than it is at ground level.
There is a chance of isolated minor to moderate daytime radio blackouts caused by M-class solar flares through Wednesday.
The 2000Z Penticton 10.7 cm solar flux index was 187 and is likely to remain about the same through at least Wednesday. The solar flux index is updated daily at 1800, 2000 and 2200Z at:
https://www.spaceweather.gc.ca/forec...-5-flux-en.php
SILSO’s latest Estimated International Sunspot Number is 138 and is likely to remain mostly unchanged through at least Wednesday. The sun’s visible disk has one large, six medium and four tiny active regions containing 49 sunspots with a total sunspot area of 885 micro-hemispheres (about four times the surface area of the Earth).
https://www.sidc.be/spaceweatherserv...tions/solarmap
Solar wind speed returned to a slow wind regime of 450 km/second or less early Tuesday gradually declining to near background levels well under 400 km/second by midday Wednesday.
Geomagnetic conditions are likely to be quiet until late Wednesday when there is a chance of unsettled to active conditions due to the CME effects.
160 and 80 meter propagation from North America to VK/ZL and the South Pacific is likely to be normal through Wednesday.
40 meter short path propagation from North America to south Asia after about 2300Z is likely to be normal Tuesday and degrading to mostly normal by late Wednesday. Short path propagation between North America and east Asia after about 0800Z is likely to be normal through Wednesday.
30 meter propagation crossing the auroral ovals and polar regions is likely to be normal degrading to mostly normal by late Wednesday. 30 meter propagation is always mildly to moderately degraded within several hours of local noon by E-region blanketing of long distance low angle F2 propagation.
20 meter propagation crossing the auroral ovals and polar regions is likely to be normal degrading to mostly normal by late Wednesday
17 and 15 meter propagation crossing the auroral ovals and polar regions is likely to be normal degrading to mostly normal by late Wednesday.17 and 15 meter long path propagation from North America to southeast and east Asia from about 1200Z to at least 1400Z is likely to be normal through Wednesday.
12 and 10 meter long distance propagation is likely to be normal degrading to mostly normal by late Wednesday. 12 and 10 meter long path propagation from North America to southeast and east Asia from about 1200Z to at least 1400Z is likely to be normal through Wednesday.
There is a slight chance of brief geographically focused 6 meter trans-Atlantic F2 propagation during mid morning hours between mid-latitude U.S states and western Europe.There is a slight chance of brief geographically focused F2 propagation enhanced by TEP over Africa from the mid-latitude US states to the Indian Ocean, equatorial and southern Africa (e.g., 3B8. 3B9, 7Q, D2, FR, V5, ZD7 and ZS) from mid morning through early afternoon. There is a slight chance of widespread 6 meter F2 trans-equatorial propagation (TEP) from mid-latitude U.S. states to South America from mid afternoon through early evening. There is a slight chance of F2 propagation enhanced by oblique-TEP from the mid-latitude US states to the south Pacific (e.g., 5W, E5, FK, ZL7 and VK/ZL during early evening hours. There is a slight chance that more northerly U.S. stations may couple into TEP and oblique-TEP via geographically focused brief intervals of F2 propagation. TEP may be significantly enhanced from late afternoon through early evening during the onset of strong to severe solar flares and geomagnetic storms then significantly degrading 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
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 persists in a southward orientation (-Bz) with IMF field strength of about 5 nanoteslas for several hours coincident with the effects of an Earth directed coronal hole high speed stream. More frequent, longer duration, minor to severe geomagnetic storms may be triggered suddenly and unpredictably when the IMF persists in a southward orientation (-Bz) with IMF field strength mildly stronger than 5 nanoteslas for at least a few hours coincident with the effects of an Earth directed CME and solar wind speed exceeding 500 km/second.

There is a slight chance of brief geographically focused F2 propagation enhanced by TEP over Africa from the mid-latitude US states to the Indian Ocean, equatorial and southern Africa (e.g., 3B8. 3B9, 7Q, D2, FR, V5, ZD7 and ZS) from mid morning through early afternoon. There is a slight chance of widespread 6 meter F2 trans-equatorial propagation (TEP) from mid-latitude U.S. states to South America from mid afternoon through early evening. There is a slight chance of F2 propagation enhanced by oblique-TEP from the mid-latitude US states to the south Pacific (e.g., 5W, E5, FK, ZL7 and VK/ZL during early evening. There is a slight chance that more northerly U.S. stations may couple into TEP and oblique-TEP via geographically focused brief intervals of F2 propagation. TEP may be significantly enhanced from late afternoon through early evening during the onset of strong to severe solar flares and geomagnetic storms then significantly degrading 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
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 persists in a southward orientation (-Bz) with IMF field strength of about 5 nanoteslas for several hours coincident with the effects of an Earth directed coronal hole high speed stream. More frequent, longer duration, minor to severe geomagnetic storms may be triggered suddenly and unpredictably when the IMF persists in a southward orientation (-Bz) with IMF field strength mildly stronger than 5 nanoteslas for at least a few hours coincident with the effects of an Earth directed CME and solar wind speed exceeding 500 km/second.

Mid-latitude northern hemisphere sunrise is 54 minutes later and sunset is 70 minutes earlier than it was on September 23rd. Sunrise is about two hours earlier and sunset is about two hours later at the 300 km altitude of the F2 region than it is at ground level.
There is a chance of minor to moderate daytime radio blackouts caused by M-class solar flares on Tuesday improving to only a slight chance on Wednesday.
The 2200Z Penticton 10.7 cm solar flux index was 133 and is likely to remain about the same through Wednesday. The solar flux index is updated daily at 1800, 2000 and 2200Z at:

The latest Estimated International Sunspot Number is 73 and is likely to remain about the same through Wednesday. The sun’s visible disk has one large, four medium and one tiny active region containing 25 sunspots with a total sunspot area of 560 micro-hemispheres (about three times the surface area of the Earth).

Solar wind speed is likely to be mildly enhanced at about 450 km/second or less with a possible moderate increase by late Wednesday due to coronal hole high speed stream effects.
Geomagnetic conditions are likely to be quiet to unsettled with a possible moderate degradation by late Wednesday due to coronal hole high speed stream effects.
160 and 80 meter propagation from North America to VK/ZL and the South Pacific is likely to be normal through Wednesday.
40 meter short path propagation from North America to south Asia after about 2300Z is likely to be normal with possible mild degradation by late Wednesday. Short path propagation between North America and east Asia after about 0800Z is likely to be mostly normal through Wednesday.
30 meter propagation crossing the auroral ovals and polar regions is likely to be mostly normal with possible mild degradation by late Wednesday. 30 meter propagation is always mildly to moderately degraded within several hours of local noon by E-region blanketing of long distance low angle F2 propagation.
20 meter propagation crossing the auroral ovals and polar regions is likely to be mostly normal with possible mild degradation by late Wednesday.
17 and 15 meter propagation crossing the auroral ovals and polar regions is likely to be mostly normal with possible mild degradation by late Wednesday. 17 and 15 meter long path propagation from North America to southeast and east Asia from about 1200Z to at least 1400Z is likely to be mostly normal through Wednesday.
12 and 10 meter long distance propagation is likely to be mostly normal with possible mild degradation by late Wednesday. 12 and 10 meter long path propagation from North America to southeast and east Asia from about 1200Z to at least 1400Z is likely to be mostly normal through Wednesday.
There is a slight chance of brief geographically focused 6 meter trans-Atlantic F2 propagation during mid to late morning hours between mid-latitude U.S states and the Mediterranean (CT, EA, F, I, SV, etc). There is a slight chance of brief geographically focused F2 propagation enhanced by TEP over Africa from the mid-latitude US states to the Indian Ocean, equatorial and southern Africa (e.g., 3B8. 3B9, 7Q, D2, FR, V5, ZD7 and ZS) from mid morning through early afternoon. There is a slight chance of widespread 6 meter F2 trans-equatorial propagation (TEP) from mid-latitude U.S. states to South America from mid afternoon through early evening. There is a slight chance of F2 propagation enhanced by oblique-TEP from the mid-latitude US states to the south Pacific (e.g., 5W, E5, FK, ZL7 and VK/ZL during early evening. There is a chance that more northerly U.S. stations may couple into TEP and oblique-TEP via geographically focused brief intervals of F2 propagation. TEP may be significantly enhanced from late afternoon through early evening during the onset of strong to severe solar flares and geomagnetic storms then significantly degrading 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
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 persists in a southward orientation (-Bz) with IMF field strength of about 5 nanoteslas for several hours coincident with the effects of an Earth directed coronal hole high speed stream. More frequent, longer duration, minor to severe geomagnetic storms may be triggered suddenly and unpredictably when the IMF persists in a southward orientation (-Bz) with IMF field strength mildly stronger than 5 nanoteslas for at least a few hours coincident with the effects of an Earth directed CME and solar wind speed exceeding 500 km/second.
