A team of scientists has, for the first time, used a single, cohesive computer model to simulate the entire life cycle of a solar flare. The comprehensive new simulation captures the formation of a solar flare in a more realistic way than previous efforts, and it includes the spectrum of light emissions known to be associated with flares.
On October 6th, the MLSO staff participated in AstroDay 2018, an educational outreach event coordinated by the Mauna Kea Observatories. 3,000 people attended. This was the second occurrence of this event, located in Kailua-Kona, on the west side of Hawaii Island.
The effect of electromagnetic variability on ionosphere-thermosphere heating in the low-altitude geomagnetic cusp is examined.
In 1844 Schwabe discovered that the number of sunspots increased and decreased over a period of about 11 years, that variation became known as the sunspot cycle.
Solar irradiance models indicate that irradiance variations are dominated by changes in disk-coverage of magnetic structures, whose brightness is thought to be determined by their size and average magnetic flux density.
