Effects of flare definitions on the statistics of derived flare distributions

Stegen, K.; Dominique, M.; Ryan, D. F. +2 more

The statistical examination of solar flares is crucial to revealing their global characteristics and behaviour. Such examinations can tackle large-scale science questions or give context to detailed single-event studies. However, they are often performed using standard but basic flare detection algorithms relying on arbitrary thresholds. This arbi…

Anomalous temporal behaviour of broadband Lyα observations during solar flares from SDO/EVE

Chamberlin, Phillip C.; Milligan, Ryan O.

Although it is the most prominent emission line in the solar spectrum, there has been a notable lack of studies devoted to variations in Lyα emission during solar flares in recent years. However, the few examples that do exist have shown Lyα emission to be a substantial radiator of the total energy budget of solar flares (of the order of 10%). It …

Solar irradiance observations with PREMOS filter radiometers on the PICARD mission: In-flight performance and data release

Egorova, T.; Schmutz, W.; Rozanov, E. +22 more

Context. The PREcision Monitoring Sensor (PREMOS) is a solar radiometer on board the French PICARD mission that was launched in June 2010 and decommissioned in April 2014.
Aims: The PREMOS radiometer obtains solar irradiance measurements in specific spectral windows in the UV, visible, and near-infrared. In this paper, the PREMOS data and cal…
