The ground-based solar telescope THEMIS performed several observations of Mercury's sodium exosphere in years 2011-2013, when the MESSENGER spacecraft was orbiting around the planet. Typical two-peak exospheric patterns were frequently identified. In previous studies, some specific cases of THEMIS Na two-peak observations were characterized and related to IMF conditions, during specific extreme cases, in the occasion of CME arrival.

Here we present enhancements of planetary ions (Na-group ions) in Mercury's northern magnetospheric cusp during flux transfer event (FTE) "showers." FTE showers are intervals of intense dayside magnetopause reconnection, during which FTEs are observed in quick succession, that is, only separated by a few seconds.

- Food consumption patterns in Europe show a decline in red meat intake, with consumers shifting towards healthier and sustainable options.
- An international study involving seven European countries analyzed consumer preferences for red meat, gathering 2,900 responses through a choice experiment.
- The findings reveal distinct differences in preferences and willingness to pay among countries, but most consumers highly value national origin and organic labels when selecting red meat products.
Article Synopsis
- The study examines consumer and non-consumer perceptions of sheep and goat meat across seven European countries, utilizing laddering and means-end chain theory.
- Consumers appreciate the unique taste and health benefits associated with sheep and goat meat, linking it to values like authenticity and enjoyment of life.
- Non-consumers, however, express disgust and negative associations, disliking the taste, odour, and fat content, and do not see any health advantages in consuming these meats.
The first evidence at Mercury of direct relation between ICME transit and Na exosphere dynamics is presented, suggesting that Na emission, observed from ground, could be a proxy of planetary space weather at Mercury. The link existing between the dayside exosphere Na patterns and the solar wind-magnetosphere-surface interactions is investigated. This goal is pursued by analyzing the Na intensity hourly images, as observed by the ground-based THEMIS solar telescope during 10 selected periods between 2012 and 2013 (with seeing, σ < = 2″), when also MESSENGER data were available.
