The increase of energetic electromagnetic flux during solar flares and particle precipitation during geomagnetic activity are among the most important sources of neutral density disturbances to the Earth's thermosphere. However, disentangling the role of X and EUV radiation during solar flares is difficult due to the rarity of sufficiently isolated EUV-enhancements. Past work investigating the role of EUV-enhancements has been based on simulations only. This study focuses on the analysis of the response of the thermosphere to relatively long-lasting (between 1 and 2 days) EUV-enhancements. These events take place in isolation from coronal mass ejections, but often occur during the recovery phase of flare events. Using the Gravity Recovery and Climate Experiment and Challenging Minisatellite Payload accelerometer-derived density datasets, we show that the EUV-enhancements slow the thermosphere's recovery from a flare, and maintain a high level density perturbation “plateau” lasting ...

With the current efforts to return humans to the Moon and the longer term goal to send people to Mars, now is the time to better understand the space weather conditions and their effects beyond the near-Earth environment. During the maximum phase of the solar activity cycle, space weather events triggered by solar flares, coronal mass ejections (CMEs) and their associated solar energetic particles (SEPs) can significantly disturb the local space environments at Earth, at the Moon and at Mars. How these extreme events impact these various planetary bodies will depend on their respective plasma environments (e.g., airless, tenuous or thick atmosphere, with or without a magnetosphere). While there are fewer extreme events related to CMEs and flares during the quiescent solar cycle phase, events triggered by corotating solar wind streams become more prominent. At the same time, very high energy particles from Galactic Cosmic Rays (GCRs) significantly increase the background space radia... [full abstract]
