  1. Regarding your latest link: DST must be the Disturbance storm time index which can also be found on this website and a quick Google search should explain in detail what the DST is. Kp is the derived Kp-index of the mentioned time I assume. The last 4 values must be values from 4 different magnetometer stations (no idea where they could be), I assume the numbers mean the deflection in nT from the quiet day curve with 0 being the baseline for a quiet day. -55 would be -55nT below the quiet day value. Don't quote me on this but I think that would be it.
  2. Im not sure if that kind of data comes in .json files. Most is in .txt files. Kp can be found in .json. You can also try to focus on magnetometer data from a station nearby?
  3. It all depends on what specific data you are looking for but it should be available on NOAA's servers. Some data comes in .json form other in .txt.

    Does your equation in any way take into account the current ambient solar wind speed
  5. 774 solar event x class what if carrington event x45

    The strength of a solar radiation storm or geomagnetic storm doesn't say all too much about the strength of a solar flare. High M-class solar flares can in theory cause the same mayhem as a high X-class solar flare but of course, stronger solar flares in general cause stronger space weather effects. It also depends how eruptive a solar flare is. We have had impulsive X-class solar flares that didn't cause any kind of noteworthy space weather effects. The X-ray emission strength of a solar flare never tells the whole story. For solar radiation storms, the location of the solar flare is also very important when it comes to how many protons are able to reach Earth. These protons follow the general direction of the Parker Spiral. The 774 event can't be 60 times stronger than the 1989 event. You do the math. The solar flare scale works like this: X1 is 10 times stronger than M1. X10 is 10 times stronger than X1. X100 is 10 times stronger than X10 and 100 times stronger than X1 . I don't think it is possible to accurately estimate the strength of a solar flare that took place such a long time ago but... well I have no idea. I'm not a scientist.
  6. 774 solar event x class what if carrington event x45

    I am unfamiliar with the 774 event. Which date was this solar flare? You mean the year 774?
  7. Smartphone Detection of geomagnetic storms

    That's a great result! Congratulations! Did you get similar readings between the smartphone and a professional magnetometer? Good to know that you got a result and the data wasn't hindered by any outside influences.
  8. Anyone Looking At VLF?

    Hello and welcome. I have no affiliation with radio communication but our Russian translator is a HAM operator and might be interested. @Alexander
  9. 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.
  10. 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.
  11. 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.
  12. 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.
  13. 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
  14. CME Math

    You're really going all in with this research of yours. I'm impressed.
  15. 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?
