oemSpace Posted May 26, 2016 Share Posted May 26, 2016 Referring to following image, I would like to know on where to find historical data (24 hour or longer) in text for Phi. Does anyone have any suggestions? Thanks in advance for any suggestions Link to comment Share on other sites More sharing options...

oemSpace Posted May 27, 2016 Author Share Posted May 27, 2016 North Pole/Negative (-) Polarity: Phi angle Between 0 and 90 or Phi angle Between 270 and 360 South Pole/Positive (+) Polarity: Phi angle Between 90 and 270 In order to determine on whether current polarity is positive or negative, you mention that Phi or Bz can be used, but when I check with ace_mag_1m, both values do not relate to each other in (+) and (-). Do you have any suggestions on which one (Bz or Long.) is better to interpret the polarity's status?

Guest EI2KK Posted August 29, 2016 Share Posted August 29, 2016 Hi there.. I am looking for historical data, but charts like in first post here... I've seen it as an archive (.gz ?) but cant find now :/ Link to comment Share on other sites More sharing options...
Marcel de Bont Posted September 1, 2016 Share Posted September 1, 2016 Didn't NOAA had some kind of national archive somewhere with all the old data? The charts aren't stored so you won't find those. You might want to try the ACE mission website see if you can generate charts there. Link to comment Share on other sites More sharing options...
Guest EI2KK Posted September 30, 2016 Share Posted September 30, 2016 Hi there.. No point to start a new topic It looks like there are two new products - does anyone know what is 'dst' parameter in http://services.swpc.noaa.gov/products/geospace/planetary-k-index-dst.json ? Link to comment Share on other sites More sharing options...
Marcel de Bont Posted September 30, 2016 Share Posted September 30, 2016 Wow, good thing you noticed this! I think this is the disturbance storm time index. A negative DST tells us the Earth's magnetic field is weakened. You can find a lot of info if you Google. This might be very useful for the site...

Guest EI2KK Posted September 30, 2016 Share Posted September 30, 2016 Hve you seen the other json product? Solar wind propagation time and all params in one file - it comes from DSCOVR, I did compare data. Do you mean disturbance since mindnight or last minute?

Marcel de Bont Posted September 30, 2016 Share Posted September 30, 2016 We've been using the DSCOVR .json file ever since it became available. Really excited to DST data from NOAA. So glad you noticed it. Link to comment Share on other sites More sharing options...
Guest EI2KK Posted September 30, 2016 Share Posted September 30, 2016 There is another interesting one, but probably you know it.. http://services.swpc.noaa.gov/experimental/text/dscovr-solar-wind-arrival.txt Values are avearaged @30re depends on speed.. waiting it in production, still experimental and sometimes is not up to date..

Vancanneyt Sander Posted September 30, 2016 Share Posted September 30, 2016 Thats one we know too we have in our dscvr graphs the earth line to know what's the data at earth instead of at L1 point where dsvr is at. dst index is interesting, we'all look at it in the forthcoming days Link to comment Share on other sites More sharing options...

I wouldnt say north pole negative and south pole positive because they switch at solar maximum and eventually they. Will be opposite 8 hours ago, EI2KK said: Hi there..

This is the one I use for DST and it really helps show how weak the IMF is and anything -50nT or lower is moderate conditions http://wdc.kugi.kyoto-u.ac.jp/dst_realtime/201609/index.html they have history that goes way back to the 50s and 60s On August 29, 2016 at 2:55 PM, EI2KK said: Hi there..

Guest EI2KK Posted October 1, 2016 Share Posted October 1, 2016 So.. why is a separate product having Kyoto's dst index only? ["2016-09-27 18:00:00","2.67","9.22976971"] ["2016-09-27 18:00:00","-24"] Values fo the same date time are different.. I think the http://services.swpc.noaa.gov/products/geospace/planetary-k-index-dst.json is kind of prediction, there is a last record right now, 18:14 UTC: ["2016-10-01 18:42:00","4.00","-33.0760002"] Link to comment Share on other sites More sharing options...
Marcel de Bont Posted October 1, 2016 Share Posted October 1, 2016 Yes you are right, we figured that out later. The 1 hour values are the quick look values and the 1 minute values are a prediction done by some kind of algorithm. Link to comment Share on other sites More sharing options...
