Manuel Luna, researcher at the IAC and the ULL, leads the team that has cataloged about 200 solar prominence oscillations detected in the first half of 2014. This analysis, published today in the Astrophysical Journal Supplement series, has served to verify that almost half of these events have been of large-amplitude. That is, oscillations with speeds between 10 km/s (36000 km/h) and 100 km/s. It has also been proven that these large-amplitude events are more common than previously thought.

The project is part of an international collaboration that began in 2015 through the International Space Science Institute (ISSI) and also the NASA project for the study of this type of oscillations.
