Zonnevlammen en Magneetstormen

Een zonnevlam (flare) is een explosie op het oppervlak van de zon, die ontstaat door het plotseling vrijkomen van de energie die wordt vastgehouden in de magnetische velden. Er ontstaat straling over het hele gebied van het elektromagnetische spectrum.

Zonnevlammen worden ingedeeld in drie hoofd-klassen:

1. X-klasse zonnevlammen.
Dit zijn uitbarstingen die op de aarde voor het uitvallen van radioverbindingen en van elektriciteitscentrales kunnen zorgen.

2. M-klasse zonnevlammen.
Dit zijn matige uitbarstingen, die rond de polen korte perioden van uitval van de radioverbindingen kunnen veroorzaken.

3. C-klasse zonnevlammen.
Kleine uitbarstingen die nauwelijks invloed hebben op de aarde.

Meer objectief worden de zonnevlammen ingedeeld aan de hand van de uitgestraalde energie (Watt per m˛ in golflengten tussen 1 en 8 ångström).
X-klasse zonnevlammen geven een energie af van meer dan 10-4 Watt/m2,
M-klasse tussen de 10-4en 10-5 en
C-klasse tussen 10-5en 10-6 Watt/m2. Iedere klasse loopt van 1 tot 9, dus bijv. C1 tot C9.

Bekende X-klasse zonnevlammen waren die van:
- Maart 1989, die grote schade aan elektriciteitscentrales in Canada veroorzaakte.
- 4 november 2003, die zo groot was dat hij niet te meten was.
Geschat wordt dat deze uitbarsting geclassificeerd moet worden als X28.

De richting van deze laatste uitbarsting was niet naar de aarde toe,
zodat het effect op aarde niet zo groot was.
Maar veroorzaakte wel poollicht dat in Nederland en zelfs tot in Portugal

Hoe maak je zelf poollicht foto"s......

Statief of zet em op een beanbag.
ISO 100 tot 400... denk er wel aan... hoe hoger de ISO des te meer ruis op de foto.
belichtingstijd tussen 15 en 25 sec. Gebruik draadontspanner, remote of zet de timer
Diafragma helemaal open
Lens 24 tot 70mm voor de mooiste resultaten

Three moderate solar flares erupted from the sun
Three moderately strong solar flares measuring M4.4, M5.3 and M2.3 erupted from Active Region 2644 (beta) on April 1 and 2, 2017. The M4.4 event started at 21:35, peaked at 21:48 and ended at 22:05 UTC. It was the first M-class solar flare since November 29, 2016 and the strongest since M5.5 on July 23, 2016.

A Type IV Radio Emission was registered at 21:50 UTC. Type IV emissions occur in association with major eruptions on the Sun and are typically associated with strong coronal mass ejections (CMEs) and solar radiation storms. However, the plasma cloud appears to be headed to the northwest and away from our planet.

Another M-class solar flare erupted from Region 2644 on April 2. This one started at 07:50, peaked at 08:02 UTC as M5.3 and ended at 08:13 UTC.

A Type IV Radio Emission was registered beginning at 08:00 UTC, indicating a strong coronal mass ejection and solar radiation storm. A Type II Radio Emission (estimated velocity 628 km/s) was registered at 08:07 UTC. Type II emissions occur in association with eruptions on the Sun and typically indicate a coronal mass ejection is associated with a flare event.

The location of this region does not favor Earth-directed CMEs.

The third M-class solar flare started at 12:52, peaked at 13:00 as M2.3 and ended at 13:11 UTC. The source was Region 2644.

A 10cm Radio Burst (peak flux 110 sfu) beginning at 12:56 and lasting 1 minute was associated with this event. A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications.

7 M-class solar flares from geoeffective region

Geoeffective Active Region 2673 produced 7 M-class and at least 8 C-class solar flares on September 4, 2017. The strongest was M5.5 at 20:33 UTC associated with an asymmetric full halo Coronal Mass Ejection (CME). This region has the potential to produce more strong to major eruptions on the Sun, including X-class flares. Its location currently favors Earth-directed CMEs.

This impressive region grew vigorously over the past 48 hours, suddenly becoming one of the largest regions of the year. It now has 'beta-gamma-delta' magnetic configuration and is capable of producing strong to major eruptions on the Sun. Since the region will remain geoeffective today and in the days ahead, Earth-directed CMEs are likely.

The first solar flare of the day was produced at 05:49 UTC measuring M1.2. It was followed by M1.5 at 15:30 UTC, M1.0 at 18:22 UTC, M1.7 (associated with a Type IV Radio Emission) at 19:37 UTC, M1.5 at 20:02 UTC, M5.5 (associated with a Type II Radio Emission and 10cm Radio Burst) at 20:33 UTC, and M2.1 at 22:14 UTC.

The strongest event from this region, thus far, is M5.5 solar flare which started at 20:28, peaked at 20:33 and ended at 20:37 UTC. This flare was associated with a Type II radio sweep with an estimated velocity of 1 472 km/s and a 10cm Radio Burst lasting 52 minutes with peak flux of 1 600 sfu.

Type II emissions occur in association with eruptions on the Sun and typically indicate a CME was produced. A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications.

Major X9.3 flare erupts from active region
A major X-class solar flare erupted from geoeffective Active Region 2673 peaking as X9.3 at 12:02 UTC on September 6, 2017. The event started at 11:53, peaked at 12:02 and ended at 12:10 UTC. This is the second X-class solar flare of the day. It comes just hours after a long-duration X2.2 at 09:33 UTC. It is also the strongest solar flare of the current solar cycle (Solar Cycle 24).

Radio signatures suggest a strong Coronal Mass Ejection (CME) was produced during this event.

The event was associated with a Type IV and Type II (estimated velocity 1969 km/s). Type II emissions occur in association with eruptions on the sun and typically indicate a coronal mass ejection is associated with a flare event. Type IV emissions occur in association with major eruptions on the sun and are typically associated with strong coronal mass ejections and solar radiation storms.

In addition, this impressive event was associated with a 10cm Radio Burst lasting 3 minutes with peak flux of 12000 sfu.

Today's X9.3 is the strongest solar flare of Solar Cycle 24. Although X-class solar flares were expected (25% chance) since Region 2673 rapidly grew into a monster region and attained 'beta-gamma-delta' magnetic configuration, such powerful flare comes as a huge surprise, as our star is heading toward Solar Minimum. The previous record for the strongest flare of the cycle was X6.9 of August 9, 2011.

The cycle so far had 47 X-class flares, including today's X2.2 and X9.3.

Over die X9.3 uitbarsting

We leven in rare tijden, dus ook de angst dat alle stroom langdurig uitvalt (Carrington Event)
X9.3 en redelijk aarde gericht, is voor mij zorgelijk. Hier de Top 50 solar flares.

Dus de vraag was moet ik voorraden aanleggen (voordat de uitbarsting vrijdagavond arriveert)?

Ik vertrouw Ben van Suspicious0bservers hierin.

"The major grid issues are now looking extremely unlikely"


Voor nu ben ik gerustgesteld.

Het houdt me bezig, dus een 2e post.
Ik hoop mijn laatste rond dit onderwerp.

De aardbeving 8.1 bij Mexico (significant earthquakes) heeft hier ook mee te maken, ga ik verder niet op in.

Dingen gebeuren wel, daardoor blijft het spannend, ik post 2 dingetjes=>

M8.1 solar flare produced
A strong solar flare measuring M8.1 at its peak erupted from Active Region 2673 at 07:49 UTC on September 8, 2017. The event started at 07:40 and ended at 07:58 UTC.

This is the third M-class solar flare of the day and the 18th since September 4, when the first M-class solar flare erupted from this region. Over those 4 days, we have also registered 3 major solar flares - X2.2, X9.3 and X1.3 and several Earth-directed CMEs. Some of them have already hit our planet, causing G4 - Severe geomagnetic storming.

There were no radio signatures associated with today's M8.1 flare suggesting a Coronal Mass Ejection (CME) was produced.

Opnieuw een X flare vandaag :)

Beetje dom. Had bovenstaande grafiek blijkbaar niet opgeslagen waardoor de grafiek van 10-09 niet meer getoond wordt. Anyway, geen X flares afgelopen twee dagen.

Ik ken dit, een dynamische link met de bron die steeds veranderd, schaam je niet.
Tof dat je plaatste, ik had die grafiek ook gezien.
Nu idd alles rustig.
Vanwege meerdere veranderingen aan de zon, blijf ik aktief volgen.
En al dan niet hier wat plaatsen, want het is een serieus onderwerp!

groetjes
