Can smartphones detect geomagnetic storms?
Written by Mateja Dumbovic Friday, 01 April 2022 08:25
A recent study by S. F. Odenwald from NASA/GSFC has shown that smartphone magnetometers can detect geomagnetic storms: “Smartphone magnetometers are being commercially explored for applications as diverse as locating customers in shopping malls for targeted advertising, to precision needle-guided surgery. Meanwhile, Earth’s geomagnetic field, whose measurement forms the basis for precision positing monitoring, varies on many timescales with significant amplitudes. This presents a challenge for high-precision position sensing that demands stability in the local geomagnetic field at the microTesla-level over timescales of minutes to hours. This study shows that many smartphone models have the sensitivity to detect geomagnetic storms caused by space weather, which means that under certain circumstances, geomagnetic storms could be a significant source of error in compass and other positioning applications. ” [Odenwald 2022]

Eugene Parker (1927-2022), a solar physics legend
Written by Mateja Dumbovic Friday, 18 March 2022 13:26
Prof. Eugene N. Parker, a solar physics legend who first proposed the concept of the solar wind and is thus a namesake of the Parker Solar Probe mission passed away on 15 March at the age of 94. His great contributions to the field of solar physics were summarized in the obituary published by the University of Chicago:
“Parker was internationally known for proposing the concept of the solar wind—an idea that was first met with skepticism to outright ridicule. The theory was later proven to be correct, reshaping our picture of space and the solar system. Parker went on to revolutionize the field of astrophysics, unraveling the complex physics behind magnetic fields in space and the dynamics of plasma. In August 2018, at the age of 91, he became the first person to witness the launch of their namesake spacecraft.
