CEDAR email: Seeking Input on Geomagnetic Conjugate Reference Map

[Kristina Collins]

Dear Colleagues,

I am working with the Polar Geospatial Center <https://www.pgc.umn.edu/> to
produce a set of reference maps showing geomagnetic conjugate relationships
between Antarctica and the Northern Hemisphere. For an idea of what this
might look like, see the attached image (Figure 4 of Lanzerotti et al,
1987: http://id.nii.ac.jp/1291/00002180/).

These maps are intended to serve researchers making interhemispheric
comparisons. For an overview of use cases for this, see Mike Hartinger's
magnetosphere seminar here:

<https://www.youtube.com/watch?v=wlU5299d6sQ&t=550s>
They may be used for communicating the importance of Antarctic space
weather measurements, education/outreach, planning instrument deployments
for conjugate studies, seeing how conjugate points change over time, etc.

Some ideas include:

   - Show locations of major stations, observation locations, etc. to
   enable at-a-glance interhemispheric comparisons (please send me the
   geographic coordinates of specific locations you'd like to see on such a
   map)
   - Create multiple versions of map from IGRF version in 1990, 2000, 2010,
   2020 etc. to see how things have evolved with changes in Earth's magnetic
   field
   - Create a similar map that projects Northern Hemisphere regions to
   Antarctica so to get a better sense of where it's possible to deploy things
   for conjugate studies (e.g., where major topographic features would impede
   deployment).
   - Show eclipse paths (ground and ionospheric elevation), including 2020
   polar eclipses and conjugate location of the 2023 and 2024 North American
   eclipse paths.


I am very interested in collecting comments, coordinates and ideas from
potential users of these maps. *If this resource is of interest to you,
please fill out this survey by 23
