Highlights of Solar and Geomagnetic Activity
03 - 09 December 2018

Solar activity was very low throughout the period. Region 2729 (S05,
L=229, class/area=Cro/50 on 06 Dec) was the only region with
sunspots and produced multiple low-level B-class flare late in the
period. A CME associated with a filament eruption on 30 Nov was
predicted to hit Earth on 05 Dec, but this event did not
materialize.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached
moderate levels on 06, and 08-09 Dec and normal levels were observed
throughout the remainder of the period.

Geomagnetic field activity reached active levels late on 09 Dec in
response to coronal hole/high speed stream effects. Quiet and quiet
to unsettled conditions were observed throughout the remainder of
the period.

Forecast of Solar and Geomagnetic Activity
10 December - 05 January 2019

Solar activity is expected to be very low throughout the outlook
period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to reach moderate levels on 10-16 Dec and 03-05 Jan with
normal flux levels expected for the remainder of the outlook period.

Geomagnetic field activity is expected to reach active levels on 10
Dec and 29 Dec due to coronal hole/high speed stream effects. Quiet
or quiet to unsettled conditions are expected throughout the
remainder of the outlook period.

Highlights of Solar and Geomagnetic Activity
12 - 18 November 2018

Solar activity was at very low levels. Region 2726 (N05, L=137,
class/area Axx/010 on 13 Nov) was inactive and decayed to plage 15
Nov. Region 2727 (N01, L=112, class/area Cao/060 on 18 Nov) showed
slight growth, but remained inactive. No Earth-directed CMEs were
observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels on 12-16 Nov and moderate levels on 17-18 Nov.

Geomagnetic field activity was at predominately quiet levels, with a
isolated periods of unsettled conditions observed early on 12 Nov.
Solar wind speeds were elevated 12-13 Nov due to a negative polarity
CH HSS. Peak speeds of 638 km/s occurred on 12 Nov at approximately
1936 UTC, and decreased over the course of the week, reaching a
minimum of 298 km/s by 17/2326 UTC. 14-17 Nov were unremarkable
under a nominal solar wind regime. The solar wind environment
underwent a slight enhancement on 18 Nov due to CIR arrival ahead of
a negative polarity CH. Total field became enhanced to 8 nT and the
Bz component saw a maximum southward deflection of -8 nT by the end
of the day. Wind speeds increased to around 330 km/s and density
increased to a peak of 20 particles per cubic cm.

Forecast of Solar and Geomagnetic Activity
19 November - 15 December 2018

Solar activity is expected to be at very low levels throughout the
forecast period (19 Nov-15 Dec). Region 2727 (N05, L=137) will exit
the solar disk on 21 Nov, and pending decay, is due to return on 04
Dec.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to remain at moderate levels 19 Nov-1 Dec. Predominately
high levels are likely 2 Dec-13 Dec due to a pair of recurrent CH
HSSs. Moderate levels are likely 14-15 Dec as CH HSS influence
wanes.

Geomagnetic field activity is expected to be at mostly unsettled
levels 19-22 Nov due to a pair of negative polarity CH HSSs.
Predominately quiet levels are expected 23-30 Nov under nominal
solar wind conditions. Active conditions are expected on 01 Dec due
to a SSBC ahead of a recurrent positive polarity CH. G1 (Minor)
storming is likely 02 Dec due to the CIR in advance of the HSS of
the aforementioned positive polarity CH. Unsettled conditions are
expected 03-06 Dec as CH HSS influence wanes. Active conditons are
likely 07-08 Dec due to HSS influence from a recurrent, negative
polarity CH. Mostly unsettled conditions, with a chance of active
intervals, is expected 09 Dec as the negative polarity CH HSS
influence wanes. Quiet conditions are expected for the remainder of
the period.

Highlights of Solar and Geomagnetic Activity
29 October - 04 November 2018

Solar activity was at very low levels. The solar disk remained
spotless through the reporting period. No Earth-directed CMEs were
observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at
normal levels with a peak flux of 28 pfu observed at 30/2015 UTC.

Geomagnetic field activity ranged from quiet to G1 (Minor) storm
levels during the period. The majority of the period was under
nominal solar wind conditions with solar wind speeds between 285-365
km/s and total field at or below 6 nT. Total field began to increase
at 04/0925 UTC and reached a maximum of 16 nT at 04/2225 UTC. The Bz
component reached a maximum southward deflection of -12 nT at
04/2129 UTC. Solar wind speed began to increase at 04/1430 UTC to a
maximum of 500 km/s at 04/2336 UTC as a positive polarity coronal
hole high speed stream (CH HSS) became geoeffective. The geomagnetic
field was quiet on 29 Oct - 03 Nov. G1 (Minor) storm levels were
observed late on 04 Nov.

Forecast of Solar and Geomagnetic Activity
05 November - 01 December 2018

Solar activity is expected to be at very low levels through the
forecast period (05 Nov - 01 Dec).

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to reach high levels on 07-16 Nov due to CH HSS influence.

Geomagnetic field activity is expected to be at unsettled to active
levels on 05-07 Nov, 10-11 Nov, and again on 01 Dec with G1 (Minor)
geomagnetic storm levels expected on 05 Nov due to recurrent CH HSS
effects.

Buongiorno.
Non vorrei sbagliarmi ma il titolo del thread è fuorviante.
Il riportare le previsioni della attività solari del NOAA è una cosa, sicuramente, molto rilevante per tutte le gamme radio e non solo per i 50 MHz.
La propagazione in 6m - almeno durante gli anni di minima - è poco "prevedibile" (almeno cercando di ricavarla dai dati pubblicati) essendo - prevalentemente - limitata al fenomeno dell'Esporadico e non leggo, poi, sull'argomento, alcuna analisi specifica.
Nei periodi di maggiore attività solare (fra 3 o 4 anni) la cosa sarà differente ma le previsioni NOAA riguarderanno, sempre e comunque, l'attività solare con relativa influenza sulle onde radio in tutte le gamme (non solo e non prevalentemente i sei metri).
Non sarebbe il caso di dare al thread un nome più corretto come, ad esempio: "Weekly Highlights and Forecasts by Noaa" o cosa similare?

Highlights of Solar and Geomagnetic Activity
10 - 16 September 2018

Solar activity was very low throughout the period. Region 2722 (S07,
Lo=215, class/area Bxo/10 on 11 Sep) produced the strongest flare of
the period, a B1 flare at 11/0759 UTC. The region decayed to plage
in the following days. No Earth-directed CMEs were observed in
available coronagraph imagery.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit ranged
from normal background to high levels. High levels were reached on
12-16 Sep and moderate levels were reached on 10-11 Sep. All
enhancements in electron flux are associated with the influence of a
positive polarity CH HSS.

Geomagnetic field activity ranged from quiet to G2 (Moderate)
geomagnetic storm levels. The onset of a CIR ahead of a positive
polarity CH HSS on 10 Sep increased geomagnetic activity to G1
levels. As wind speeds increased to around 550 km/s on 11 Sep,
geomagnetic activity further increased to G2 (Moderate) geomagnetic
storm levels. Total magnetic field strength (Bt) peaked at 15 nT
late on 10 Sep. Bt then decreased to near 5-6 nT by mid-day on 11
Sep, which decreased the geomagnetic response to mostly quiet to
active levels. One additional period of isolated G1 (Minor)
geomagnetic storming was observed early on 14 Sep. Wind speeds
persisted at elevated levels through 16 Sep, with a notable increase
to a peak around 650 km/s observed early on 15 Sep. As wind speeds
decreased, quiet to unsettled levels on 15 Sep gave way to quiet
levels on 16 Sep.

Forecast of Solar and Geomagnetic Activity
17 September - 13 October 2018

Solar activity is expected to be very low throughout the outlook
period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at moderate levels on 06-08 Oct and at high levels
for the remainder of the outlook period. All enhancements in
electron flux are expected due to multiple, recurrent CH HSSs.

Geomagnetic field activity is expected to range from quiet to G2
(Moderate) geomagnetic storm levels. G2 (Moderate) geomagnetic storm
levels are expected on 08 Oct; G1 (Minor) geomagnetic storm levels
are expected on 07 Oct and 10 Oct; active conditions are expected on
17 Sep, 23 Sep, 02 Oct and 11 Oct; unsettled conditions are expected
on 18 Sep, 24 Sep, 01 Oct, 09 Oct and 12 Oct. All levels of elevated

Grazie per aver cambiato il titolo Silverio mutandolo da "propagazione 50 MHz" all'attuale molto più corretto... Ancora complimenti per il tuo lavoro di ricerca e diffusione!

Highlights of Solar and Geomagnetic Activity
10 - 16 September 2018

Solar activity was very low throughout the period. Region 2722 (S07,
Lo=215, class/area Bxo/10 on 11 Sep) produced the strongest flare of
the period, a B1 flare at 11/0759 UTC. The region decayed to plage
in the following days. No Earth-directed CMEs were observed in
available coronagraph imagery.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit ranged
from normal background to high levels. High levels were reached on
12-16 Sep and moderate levels were reached on 10-11 Sep. All
enhancements in electron flux are associated with the influence of a
positive polarity CH HSS.

Geomagnetic field activity ranged from quiet to G2 (Moderate)
geomagnetic storm levels. The onset of a CIR ahead of a positive
polarity CH HSS on 10 Sep increased geomagnetic activity to G1
levels. As wind speeds increased to around 550 km/s on 11 Sep,
geomagnetic activity further increased to G2 (Moderate) geomagnetic
storm levels. Total magnetic field strength (Bt) peaked at 15 nT
late on 10 Sep. Bt then decreased to near 5-6 nT by mid-day on 11
Sep, which decreased the geomagnetic response to mostly quiet to
active levels. One additional period of isolated G1 (Minor)
geomagnetic storming was observed early on 14 Sep. Wind speeds
persisted at elevated levels through 16 Sep, with a notable increase
to a peak around 650 km/s observed early on 15 Sep. As wind speeds
decreased, quiet to unsettled levels on 15 Sep gave way to quiet
levels on 16 Sep.

Forecast of Solar and Geomagnetic Activity
17 September - 13 October 2018

Solar activity is expected to be very low throughout the outlook
period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at moderate levels on 06-08 Oct and at high levels
for the remainder of the outlook period. All enhancements in
electron flux are expected due to multiple, recurrent CH HSSs.

Geomagnetic field activity is expected to range from quiet to G2
(Moderate) geomagnetic storm levels. G2 (Moderate) geomagnetic storm
levels are expected on 08 Oct; G1 (Minor) geomagnetic storm levels
are expected on 07 Oct and 10 Oct; active conditions are expected on
17 Sep, 23 Sep, 02 Oct and 11 Oct; unsettled conditions are expected
on 18 Sep, 24 Sep, 01 Oct, 09 Oct and 12 Oct. All levels of elevated
geomagnetic activity are due to the anticipated influence of
multiple, recurrent CH HSSs.
