  1. Aurora in Ontario, Canada

    Have you tried some aurora hunting yesterday? Or perhaps you are going to give it a shot today? The moon remains troublesome however but you might enjoy the image I made yesterday from Sweden.
  2. Aurora in Ontario, Canada

    Hello and welcome. I have no experience myself with the northern lights in Ontaria as I come from Europe, but some good rules to keep in mind are that you should try to avoid as much light pollution as possible and a new moon also helps a lot especially if the aurora is weak. The aurora is a bit more active in September and March (weeks around the equinoxes) but in theory they can be seen all year round as long as your skies are dark around midnight. Clouds are of course also a big problem. Toronto is a bit to the south but your magnetic latitude is okay. If you take the above advice into account you should have a chance during minor G1 geomagnetic storm conditions. You are maybe in luck tonight as we are seeing some very decent solar wind stats at the moment but the moon is a big problem tonight.
  3. Far side

    De linker kant en een stukje rechts is het aardegerichte deel. Komt overeen met de indicaties op de bovenste kaart. Maar goed, blijft het niks vinden deze kaarten.
  4. Far side

    De onderste afbeelding is een samenvoegsel van beelden van twee verschillende satellieten en laat de hele Zon zien. Het zwarte stukje is een gedeelte van de Zon waar geen beelden van zijn. Dit komt omdat een sattaliet genaamd STEREO B al een tijdje buiten werking is. De bovenste kaart is een computer impressie van waar mogelijk zonnevlekken te zien zijn. Het gebied gemarkeert met ''farside'' is de achterkant van de Zon, oftewel het deel dat we niet kunnen zien vanaf die Aarde. Ben zelf absoluut geen fan van die bovenste kaart. Zoals je ziet zijn er een hoop rare zwarte vlekjes te zien op het ''farside'' gedeeld wat echt nergens op slaat, er zijn daar echt niet zoveel zonnevlekken.
  5. Website

    Geen idee of u dit weet maar wij hebben een soort gelijk archief, met interactieve grafieken. Kijk en geniet! https://www.poollicht.be/nl/archief/2017/09/06/xray
  6. CME Math

    You're really going all in with this research of yours. I'm impressed.
  7. CME, Solar Winds & Earthquakes

    I'm not calling anyone names. I am just quoting a tweet of a very respected solar scientist. I even showed my support in my previous post, as I believe that if someone can prove that earthquakes and solar activity are related, the discovery could well be worthy of a Nobel Prize in my opinion. What I like to see is an explanation that explains exactly how space weather triggers earthquakes. What is it that space weather does to trigger these quakes. I don't just want to hear theories, it has to be supported by evidence. There isn't any evidence yet, only people correlating quakes with solar events. But solar events are common and so are quakes so you are bound to hit the jackpot a couple of times, but that doesn't proof they are related? Yes space weather influences our magnetic field but what does that have to do with plate tectonics? Any evidence I have seen thus far seem to be more based on random luck of random solar events occurring at the same time as an earthquake. Also, earthquakes remain a common occurrence even during solar minimum. According to the logic of this theory, shouldn't there be a significant decrease of earthquakes during solar minimum? Or less earthquakes during a weak solar maximum than during a strong solar maximum?
  8. CME, Solar Winds & Earthquakes

    Hello Paul, There is currently no solid verified scientific evidence that link space weather and earthquake activity in any way. There are indeed certain communities that do their own research and aim to link the two together or claim to have done that but this is what I'd call ''back yard'' science which should be approached with a healthy dose of common sense. There is a tweet from very respected solar scientist Karl Battams that I always remember when these discussion pop up. It's too funny not to share: Everyone is however of course entitled to their opinion and if you manage to prove a correlation between solar activity and earthquake activity you might win a Nobel Prize. Who knows!
  9. White aurora phenomen on the night to 14.11.2012

    I wish I was better at understanding why aurora forms the way they do but unfortunately I do not know much about this subject. My personal experience is that aurora can become incredible intense and diverse during major sub storms. I must admit that I don't remember ever seeing white patches as on the 22:40 UTC images, but I did see white during very intense displays where the green becomes saturated in some way and turns almost white. But your example doesn't look that bright. It's just white. I don't think the picket fence is related to STEVE. The times I have seen what people call STEVE today it was clearly separated from the main aurora zone and located at a lower latitude than the main aurora was. My answers are just my personal experiences.
  10. Actief Gebied op komst?

    De Type II en IV radio emissions (de term ''sweeps'' word soms ook gebruikt) hebben inderdaad te maken met deze uitbarsting(en) De eruptie produceerde een schok in de corona (de atmosfeer van de Zon) en deze schokgolf bereikte het aardegerichte deel van de Zon. Ik heb een animatie bijgevoegd waar je deze schokgolf kan zien als je goed kijkt. Deze schokgolf is waar te nemen als een kenmerkend soort ruis in een bepaald radio frequentie gebied en zijn zeer goede indicatoren dat er een mogelijk eruptieve gebeurtenis heeft plaats gevonden op de Zon. Om het verhaal compleet te maken: z'n schokgolf accelereert electronen die bepaalde radio golven beginnen te produceren en die kunnen we oppikken.
  11. Actief Gebied op komst?

    Er zijn helaas geen beelden van STEREO Ahead die het hele verhaal vertellen maar het gebeurde bij de restanten van oud zonnevlekkengebied 2673. Het lijkt op een filament eruptie (CME 1) die gevolgd werd door mogelijk een flare (CME 2) maar dit is grotendeels speculatie van mij. Uiteraard hebben de twee planeten die jij noemt niks te maken met activiteit van de Zon.
  12. Smartphone Detection of geomagnetic storms

    That would be really interesting to know. But doesn't that require people to be in very remote locations and make long term observations?
  13. X-ray emissions drop

    A small correction. The Sun gets blocked by the Earth, during eclipse season around the equinoxes.
  14. Poollicht 14/15 september 2017

    De activiteit van afgelopen nacht komt van een coronaal gat. We maken hier regelmatig melding van in het Engels zoals in dit nieuws artikel. Hier kan je meer lezen over coronale gaten. Zou best poollicht kunnen zijn, zwak en ver weg. Airglow zou meer over de gehele hemel gespreid moeten zijn? Op je eerste foto lijkt er wat rood boven de wolken te zitten ook.
  15. Sunspot region 2673

    Solar activity has plunged to very low levels with the disappearance of sunspot region 2673. What a week it was. Sunspot region 2673 grew from a simple Alpha sunspot to one of the most complex sunspot regions of Solar Cycle 24 in just 48 hours. It managed to produce a mind blowing 27 M-class solar flares and 4 X-class solar flares, including the strongest and second strongest solar flare of Solar Cycle 24. To top it of, it even caused a severe G4 geomagnetic storm at Earth. A sunspot region to remember for sure. We look back at this hectic week in our latest YouTube video where we look at the development of sunspot region 2673, the X-class solar flares and the M5.5 solar flare that launched a coronal mass ejection towards our planet. The video is full with never before seen footage so be sure to check it out! Give the video a like and a share. If you have energy left than even a comment is very much welcome! Your engagement is very much appreciated. It took us a little while to make this video! Enjoy!
