Results of the summarizing process for the arXiv paper: 1605.01444v1

The Solar Aspect Monitor (SAM) is a pinhole camera on the Extreme-ultraviolet Variability Experiment (EVE) aboard the Solar Dynamics Observatory (SDO). SAM projects the solar disk onto the CCD through a metallic filter designed to allow only solar photons shortward of 7 nm to pass. In this study, researchers present a technique for isolating the 0.01-7 nm integrated irradiance from the SAM signal to produce the first results of broadband irradiance for the time period from May 2010 to May 2014. The results of this analysis agree with a similar data product from EVE's EUV SpectroPhotometer (ESP) to within 25%. The study compares these results with measurements from other instruments such as Student Nitric Oxide Explorer (SNOE) Solar X-ray Photometer (SXP) and Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) Solar EUV Experiment (SEE) at similar levels of solar activity. The full-disk SAM broadband results compare well to other measurements of the 0.01-7 nm irradiance. Furthermore, researchers explore SAM's capability toward resolving spatial contribution from regions of solar disk in irradiance and demonstrate this feature with a case study of several strong flares that erupted from active regions on March 11, 2011. This study provides valuable insights into understanding how different parts of the sun contribute to overall solar radiation output and can aid in predicting space weather events that can impact Earth's technological infrastructure. The findings are published in Journal of Geophysical Research: Space Physics.

Exploring the Solar Aspect Monitor (SAM): A New Technique for Measuring Broadband Irradiance

The Sun is an ever-changing source of energy, and understanding its variability is essential to predicting space weather events that can impact Earth’s technological infrastructure. To better understand the Sun’s radiation output, a team of researchers has developed a new technique for measuring broadband irradiance using the Solar Aspect Monitor (SAM) aboard the Extreme-ultraviolet Variability Experiment (EVE) on board the Solar Dynamics Observatory (SDO). The results of this study have been published in Journal of Geophysical Research: Space Physics.

What Is SAM?

SAM is a pinhole camera designed to measure solar disk emission shortward of 7 nm. It projects images onto a charge-coupled device (CCD) through a metallic filter that allows only solar photons shorter than 7 nm to pass. This enables SAM to measure integrated irradiance from 0.01–7 nm over full disk images with high temporal resolution.

Measuring Broadband Irradiance Using SAM

In this study, researchers present a technique for isolating 0.01–7 nm integrated irradiance from the SAM signal and producing results covering May 2010–May 2014—the first such measurements obtained by SAM over this time period. The results were compared with similar data products from EVE’s EUV SpectroPhotometer (ESP), as well as measurements from other instruments such as Student Nitric Oxide Explorer (SNOE) Solar X-ray Photometer (SXP) and Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) Solar EUV Experiment (SEE). At similar levels of solar activity, these results agreed within 25%.

Furthermore, researchers explored SAM’s capability towards resolving spatial contribution from regions of the solar disk in irradiance and demonstrated this feature with a case study involving several strong flares that erupted from active regions on March 11th 2011. These findings provide valuable insights into understanding how different parts of the sun contribute to overall solar radiation output and can aid in predicting space weather events that can affect Earth's technological infrastructure.

Conclusion

This research provides important insights into understanding how different parts of the sun contribute to overall solar radiation output which could help predict space weather events that could potentially harm Earth's technological infrastructure. By isolating 0.01–7nm integrated irradiance from the SAM signal, researchers were able to produce results covering May 2010–May 2014—the first such measurements obtained by SAM over this time period—and compare them with similar data products from other instruments at similar levels of solar activity with agreement within 25%. Furthermore, they explored SAM's capability towards resolving spatial contribution from regions on the sun's surface in order to gain further insight into its effects on our planet's environment and technology systems
