- (astronomy) A longitude described in terms of solar coordinates.
- 2015, F. Fraschetti, “Cross-field transport and pitch-angle anisotropy of solar energetic particles in MHD turbulence”, in arXiv[1]:
- Recent modelling of solar energetic particles (SEPs) propagation through the heliospheric turbulence, also discussed in this workshop, has investigated the role of the pitch-angle scattering and the perpendicular transport in spreading particles in heliolongitude, as shown by multi-spacecraft measurements (STEREO A/B, ACE, SOHO, etc.) at 1 AU in various energy ranges.
