In the Solar Section website you will find information for all things Solar within JHUAPL: details, raw data and results from our past and future balloon and rocket projects; high level data products and pretty images from the telescopes aboard the STEREO mission; and results from our research activities funded by NASA, NSF and DoD.

The Solar Section team is heavily involved in Scientific Ballooning, Parker Solar Probe and Solar Orbiter science and the STEREO and SOHO missions. The APL team includes four full-time APL staff and two young scientists from GMU (on-site at APL). The team is augmented by close collaborators working off-site but visiting frequently.

APL Staff

  • Angelos Vourlidas (Section Supervisor): CMEs, Space Weather, space instrumentation
  • Pietro Bernasconi: Magnetic Field observations and magnetographs, Filaments, balloon instrumentation
  • Aleida K. Higginson: Solar Wind, MHD modeling
  • Nour E. Raouafi: Coronal Spectroscopy and polarimetry, plumes, jets, shocks, Comets

On-Site Non-Employees (OSNE)

  • Carlos Braga (GMU): CMEs, image processing
  • Tanmoy Smanata (GMU): EUV analysis, spectroscopy

Close Collaborators

  • Laura Balmaceda (GMU): CMEs, shocks, image Processing


The Solar Section maintains strong ties with the Solar & Heliospheric Physics Branch at the U.S. Naval Research Laboratory and the Solar Physics Laboratory at the NASA Goddard Space Flight Center. It collaborates extensively with scientists from the Jet Propulsion Laboratory, University of Göttingen, Germany, and University of Ioaninna, Greece.
