Q: How much data can I download?
A: As much as you like.
Q: Why are there no data from my event?
A: SuperMAG is funded to enable research. Three reasons:
  1. SuperMAG is not funded to provide real-time or near-real-time data.
  2. We work on a single standard grant and do our best to update the data holdings.
  3. We must wait for data to be released from collaborators.
Q: I have made a cool plot and want to share it with my colleague.
A: Copy the URL from your browser and mail to your colleague. He/she can simple click it and an identical plot will be generated. All settings are included in the URL.
Q: Why is Kyoto-AL smaller than SML and/or Kyoto-AU larger than SMU?
A: In principle this should not be possible. However, there are three possible reasons:
  1. Differences in baseline technique.
  2. Kyoto has stations that are not yet included in SuperMAG.
  3. Errors in data.
Q: Why is SMR not the same as SYMH?
A: These do not necessary the same. Two reasons:
  1. The stations used to derive these indices are not the same.
  2. Differences in baseline technique.
Q: Why do I need to register to download data/plots/movies?
A: This is done to ensure future funding for SuperMAG collaborators and SuperMAG. We track usage and report back to collaborators which use this information to ensure continued funding.
