EXTERNAL EFFECTS
September 20, 2024
The planetary geomagnetic field today saw quiet conditions with AP 7. High latitudes saw quiet conditions with AP 6. Medium latitudes saw quiet disturbed conditions with AP 6.
Unsettled conditions in the geomagnetic field are likely September 21 with quiet conditions September 22-23. Solar activity is expected to be at moderate levels September 21-23 with a moderate chance (35%) of an M-class flare and 10% chance of an X-class flare. A proton storm is expected with 10% probability in this time period.
The maximum disturbance in the geomagnetic field today occurred with KP 3 at 12:00 UT on September 20, 2024.
The Wolf Sunspot number today was 113. Solar radio Flux 10.7 was 154 on September 20, 2024.
An X1.3 class solar flare occurred on September 12, 2024. A strong M5.6 solar flare also occurred
near UT midnight today. This flare occurred near local solar noon in Vanuatu
where a series of strong quakes occurred today. A moderately strong solar flare
of about M3.6 also occurred shortly after 06:00 UT today. It was followed by
a series of moderate earthquakes in the Red Sea of M 4.5-5.0 beginning at 06:20 UT and continuing to local solar noon. SWPC reported these flares with the following parameters:
The X-class flare is likely to promote unusual and strong earthquakes in
the next three days. This enhanced solar flare activity is due to a series
of strong sunspots rotating back to a geo-effective position after their last
arrival with X-flares and strong geomagnetic storms starting near August 12, 2024.
Some of the most notable activity with these August events included a moderate
earthquake in Los Angeles, California and if the area is still sensitive
a recurrence of that activity is possible at this time and in mid-October.

EXTERNAL EFFECTS
September 19, 2024
The planetary geomagnetic field today saw active conditions with AP 20. High latitudes saw stormy conditions with AP 39. Medium latitudes saw disturbed conditions with AP 15.
Unsettled conditions in the geomagnetic field are likely September 21 with quiet conditions September 20 and 22. Solar activity is expected to be at moderate levels September 20-22 with a moderate chance (55%) of an M-class flare and 15% chance of an X-class flare. A proton storm is expected with 10% probability in this time period.
The maximum disturbance in the geomagnetic field today occurred with KP 6 at 15:00 UT on September 19, 2024.
The Wolf Sunspot number today was 109. Solar radio Flux 10.7 was 161 on September 19, 2024.
An X1.3 class solar flare occurred on September 12, 2024. A strong M5.6 solar flare also occurred
near UT midnight today. This flare occurred near local solar noon in Vanuatu
where a series of strong quakes occurred today. A moderately strong solar flare
of about M3.6 also occurred shortly after 06:00 UT today. It was followed by
a series of moderate earthquakes in the Red Sea of M 4.5-5.0 beginning at 06:20 UT and continuing to local solar noon. SWPC reported these flares with the following parameters:
The X-class flare is likely to promote unusual and strong earthquakes in
the next three days. This enhanced solar flare activity is due to a series
of strong sunspots rotating back to a geo-effective position after their last
arrival with X-flares and strong geomagnetic storms starting near August 12, 2024.
Some of the most notable activity with these August events included a moderate
earthquake in Los Angeles, California and if the area is still sensitive
a recurrence of that activity is possible at this time and in mid-October.

EXTERNAL EFFECTS
September 16, 2024
The planetary geomagnetic field today saw active conditions with AP 23. High latitudes saw active storm conditions with AP 43. Medium latitudes saw active conditions with AP 19.
Major storm conditions in the geomagnetic field are likely September 17 with unsettled conditions September 18-19. Solar activity is expected to be at moderate levels September 17-19 with a moderate chance (55%) of an M-class flare and 15% chance of an X-class flare. A proton storm is expected with 20% probability in this time period.
The maximum disturbance in the geomagnetic field today occurred with KP 7 at 09:00 UT on September 16, 2024.
The Wolf Sunspot number today was 103. Solar radio Flux 10.7 was 170 on September 16, 2024.
An X1.3 class solar flare occurred on September 12, 2024. A strong M5.6 solar flare also occurred
near UT midnight today. This flare occurred near local solar noon in Vanuatu
where a series of strong quakes occurred today. A moderately strong solar flare
of about M3.6 also occurred shortly after 06:00 UT today. It was followed by
a series of moderate earthquakes in the Red Sea of M 4.5-5.0 beginning at 06:20 UT and continuing to local solar noon. SWPC reported these flares with the following parameters:
The X-class flare is likely to promote unusual and strong earthquakes in
the next three days. This enhanced solar flare activity is due to a series
of strong sunspots rotating back to a geo-effective position after their last
arrival with X-flares and strong geomagnetic storms starting near August 12, 2024.
Some of the most notable activity with these August events included a moderate
earthquake in Los Angeles, California and if the area is still sensitive
a recurrence of that activity is possible at this time and in mid-October.
A strong Gamma Ray Burst was recorded by SWIFT on August 24, 2024 at 01:03:25 UT (#240824A). A preliminary UVOT Magnitude of V>18.7 was assigned to this GRB.

where a series of strong quakes occurred today. A moderately strong solar flare
of about M3.6 also occurred shortly after 06:00 UT today. It was followed by
a series of moderate earthquakes in the Red Sea of M 4.5-5.0 beginning at 06:20 UT and continuing to local solar noon. SWPC reported these flares with the following parameters:
The X-class flare is likely to promote unusual and strong earthquakes in
the next three days. This enhanced solar flare activity is due to a series
of strong sunspots rotating back to a geo-effective position after their last
arrival with X-flares and strong geomagnetic storms starting near August 12, 2024.
Some of the most notable activity with these August events included a moderate
earthquake in Los Angeles, California and if the area is still sensitive
a recurrence of that activity is possible at this time and in mid-October.

EXTERNAL EFFECTS
September 11, 2024
The planetary geomagnetic field today saw quiet conditions with AP 8. High latitudes saw quiet conditions with AP 4. Medium latitudes saw quiet conditions with AP 8.
Minor storm conditions in the geomagnetic field are likely September 12 with major storms September 13 and active September 14. Solar activity is expected to be at moderate levels September 12-14 with a moderate chance (55%) of an M-class flare and 15% chance of an X-class flare. A proton storm is expected with 10% probability in this time period.
The maximum disturbance in the geomagnetic field today occurred with KP 3 at 21:00 UT on September 11, 2024.
The Wolf Sunspot number today was 179. Solar radio Flux 10.7 was 207 on September 11, 2024.
An X1.3 class solar flare occurred on September 12, 2024. A strong M5.6 solar flare also occurred
near UT midnight today. This flare occurred near local solar noon in Vanuatu
where a series of strong quakes occurred today. A moderately strong solar flare
of about M3.6 also occurred shortly after 06:00 UT today. It was followed by
a series of moderate earthquakes in the Red Sea of M 4.5-5.0 beginning at 06:20 UT and continuing to local solar noon. SWPC reported these flares with the following parameters:
The X-class flare is likely to promote unusual and strong earthquakes in
the next three days. This enhanced solar flare activity is due to a series
of strong sunspots rotating back to a geo-effective position after their last
arrival with X-flares and strong geomagnetic storms starting near August 12, 2024.
Some of the most notable activity with these August events included a moderate
earthquake in Los Angeles, California and if the area is still sensitive
a recurrence of that activity is possible at this time and in mid-October.
A strong Gamma Ray Burst was recorded by SWIFT on August 24, 2024 at 01:03:25 UT (#240824A). A preliminary UVOT Magnitude of V>18.7 was assigned to this GRB.
A strong Gamma Ray Burst was recorded by SWIFT on August 24, 2024 at 13:11:16 UT (#240824B). No preliminary UVOT Magnitude was assigned to this GRB.
A strong Gamma Ray Burst was recorded by SWIFT on August 25, 2024 at 15:52:59 UT (#240825A). A preliminary UVOT Magnitude of V>17.2 was assigned to this GRB.
SOLAR FLARE ACTIVITY
Where applicable the strongest earthquakes associated with the largest flares
are listed. This may give some indication where SFE will be most likely in the
near future.

EXTERNAL FIELDS/EFFECTS
September 8, 2024
The planetary geomagnetic field today saw quiet conditions with AP 9. High latitudes saw quiet conditions with AP 5. Medium latitudes saw disturbed conditions with AP 19.
Quiet to unsettled conditions in the geomagnetic field are likely September 9 with major storms September 10 and minor storms September 11. Solar activity is expected to be at moderate levels September 9-11 with a moderate chance (55%) of an M-class flare and 15% chance of an X-class flare. A proton storm is expected with 10% probability in this time period.
The maximum disturbance in the geomagnetic field today occurred with KP 6 at 21:00 UT on September 8, 2024.
The Wolf Sunspot number today was 176. Solar radio Flux 10.7 was 228 on September 8, 2024.
A strong Gamma Ray Burst was recorded by SWIFT on August 24, 2024 at 01:03:25 UT (#240824A). A preliminary UVOT Magnitude of V>18.7 was assigned to this GRB.
A strong Gamma Ray Burst was recorded by SWIFT on August 24, 2024 at 13:11:16 UT (#240824B). No preliminary UVOT Magnitude was assigned to this GRB.
A strong Gamma Ray Burst was recorded by SWIFT on August 25, 2024 at 15:52:59 UT (#240825A). A preliminary UVOT Magnitude of V>17.2 was assigned to this GRB.
SOLAR FLARE ACTIVITY
Where applicable the strongest earthquakes associated with the largest flares
are listed. This may give some indication where SFE will be most likely in the
near future.
