What sustained multi-disciplinary research can achieve: The space weather modeling framework

Liemohn, Michael W.; van der Holst, Bart; Sokolov, Igor V. +15 more

Magnetohydrodynamics (MHD)-based global space weather models have mostly been developed and maintained at academic institutions. While the "free spirit" approach of academia enables the rapid emergence and testing of new ideas and methods, the lack of long-term stability and support makes this arrangement very challenging. This paper describes a s…

SunCET: The Sun Coronal Ejection Tracker Concept

Veronig, Astrid M.; Dissauer, Karin; Chamberlin, Phillip C. +16 more

The Sun Coronal Ejection Tracker (SunCET) is an extreme ultraviolet imager and spectrograph instrument concept for tracking coronal mass ejections through the region where they experience the majority of their acceleration: the difficult-to-observe middle corona. It contains a wide field of view (0-4 R_⊙) imager and a 1 Å spectral-resolu…

Analysis of signal to noise ratio in coronagraph observations of coronal mass ejections

West, Matthew J.; Nicula, Bogdan; Bothmer, Volker +7 more

We establish a baseline signal-to-noise ratio (SNR) requirement for the European Space Agency (ESA)-funded Solar Coronagraph for OPErations (SCOPE) instrument in its field of view of 2.5-30 solar radii based on existing observations by the Solar and Heliospheric Observatory (SOHO). Using automatic detection of coronal mass ejections (CMEs), we ana…
