PSI focuses (in part) on the development and application of global MHD models of the Sun's corona and heliosphere to answer fundamental scientific questions.

@ESASolarOrbiter @NASAScience_ @esa @SwRI @IAC_Astrofisica We are grateful for dedicated resources from the ACCESS program, the Expanse supercomputer at the @SDSC_UCSD, and NASA's Advanced Supercomputing Division for allocations on Athena. Thanks to the #SDO/#HMI and the @ESASolarOrbiter PHI teams for near-real time vector magnetograms.

¿Cómo será la corona solar que veremos el 12 de agosto?🌞 El director del IAC, Valentín Martínez Pillet, explica cómo el IAC y @predsci la consiguen prededir mediante simulaciones realizadas con el Superordenador de La Palma. #Eclipse2026 👇

We assimilate magnetic field data from SDO/HMI into the High-performance Flux Transport (HipFT) surface flux transport model, producing full-Sun maps approximating the magnetic field over time. These maps are then used to drive our time-dependent coronal and heliospheric model.

As has been our tradition for over 30 years, Predictive Science is predicting the structure of the corona for the upcoming total solar eclipse on August 12, 2026!

There are several new features in the model this year, keep reading for details!

[Predictive Science Inc. @predsci]

We employ a continuously running prediction model updated in near real time. As totality approaches, the prediction materials will become more accurate in time. The solar cycle is still near its peak, and the corona's appearance changes significantly over several days.

Our POT3D code (https://t.co/oHV8EasgWT), which is part of SWiG, has been accepted and released as part of the new SPEC CPU 2026 Benchmark suite!

While other effects (e.g., electron scattering) must also be accounted for when comparing simulations to in-situ data, these results underline the importance of including surface magnetic flux evolution when investigating magnetic connectivity of the corona and heliosphere.

[Predictive Science Inc. @predsci]

🚨 New paper alert! 🚨
PSI's Roberto Lionello led a team (including U of Reading's Matt Owens) to investigate the magnetic connectivity of the corona/heliosphere system under busy (solar maximum) and quiet (solar minimum) conditions. Details below!

Lionello et al. developed a method to identify folded field lines in the models, allowing for easy comparison with in-situ strahl statistics. The time-dependent runs agree well with ACE/WIND data, while the steady-state runs contain too little disconnected and folded flux.
