Flare activity in a solar active region known as NOAA 11861 has provided a wealth of data from NASA Interface Region Imaging Spectrograph spacecraft, shedding new light on the behavior of molecular hydrogen (H?) in the Sun's lower atmosphere. A study led by NSO scientist Dr. Sarah Jaeggli has identified 37 new H? emission lines, enhancing our understanding of the Sun’s lower atmospheric structure during solar flares. H? emission occurs through fluorescence; which is exactly like fluorescence of neon colors from a black light—the flare radiation is the black light, and the H? is the thing that makes the pretty colors. According to Dr. Jaeggli, “For the most part, molecules are ignored in the physics of the Sun, included in simulations, but they might be important in very cool regions, in which case, we are modeling the Sun wrong by excluding them.” Read more about it after the jump! https://lnkd.in/gD8VHXpP

We had an amazing time at the Girl Scouts of Hawai'i STEM Fest on Oahu, Hawai'i! Thank you to the Girl Scouts for hosting this incredible event at the Pearl Harbor Aviation Museum, and allowing us to share the wonders of the Sun with the next generation of women scientists and STEM professionals. We look forward to Maui's STEM Fest happening this Saturday, 11/09, at the Maui Arts & Cultural Center! #GirlScoutsHI #STEMFest2024

MAGFiLO is a highly detailed dataset with expert annotations for 10,244 solar filaments. Its purpose is to train machine learning models to automatically identify and analyze solar filaments in real-time using data from the U.S. National Science Foundation (NSF) Global Oscillation Network Group (GONG). This will enhance early filament detection, improve space weather prediction models, and help keep us one step ahead of the Sun's most extreme outbursts. The development of MAGFiLO represents the convergence of two rapidly advancing fields - solar physics and Artificial Intelligence. This dataset, captured by NSF GONG stations operated by the NSF National Solar Observatory with support from the NOAA: National Oceanic & Atmospheric Administration, is the result of 1,593 solar observations and over 1,000 person-hours of expert manual annotation and review processes. The application of AI/ML to the study of solar filaments signals a transformative phase in solar physics. These findings were published in Nature'sa Scientific Data journal.

Three National Science Foundation (NSF) National Solar Observatory NISP scientists - Kiran Jain, Gordon Petrie,?and?Alexei Pevtsov - are attending the Solar Cycle Variability: From Understanding to Making Prediction conference in Nainital,?India! Kiran (pictured) presented a solicited talk titled "Solar-cycle related changes below the surface of the Sun," Gordon gave an invited talk on "Polarity reversals of the solar magnetic field," and Alexei gave an invited review titled "Studies on the solar magnetic field." Many conference presentations by non-NSO participants included NSF GONG and NSF SOLIS data, mainly magnetograms, but also helioseismic data and results on internal solar rotation, meridional flows, and torsional oscillations. Magnetograms were used in Coronal Mass Ejections/flare studies, machine learning, and solar cycle studies. Alexei also took questions about the next generation ngGONG!

Congrats to National Science Foundation (NSF) NSO Scientist Gordon Petrie (right) on receiving Springer Nature's 2024?Kees de Jager Prize for the best article published in the journal Solar Physics in 2023!???? Full announcement: https://lnkd.in/gwtbHaY4

In a remarkable breakthrough, a group of scientists led by U.S. National Science Foundation (NSF) National Solar Observatory (NSO) scientist Tetsu Anan has unveiled the scale of electric fields driving explosive phenomena in the solar atmosphere. The team used unique data from the NSF Daniel K. Inouye Solar Telescope, built and operated by the NSO. They discovered that the spatial scale of these electric fields reach a staggering one megameter, challenging prior estimates around the centimeter to meter range. These findings, published in Nature Communications, challenge long-held assumptions about the triggers behind solar flares, and other energetic solar events.

Two key instruments, the Vector Spectromagnetograph and the Full Disk Patrol, were successfully installed on the main telescope mount of the U.S. National Science Foundation (NSF) Synoptic Optical Long-term Investigations of the Sun (SOLIS) facility at Big Bear Solar Observatory, in California. This marks a significant step forward in bringing SOLIS to first light! https://lnkd.in/gSEkPUXQ
