The first generation of ELT instruments includes an optical-infrared high resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes Dispersion Echelle Spectrograph). consists three fibre-fed spectrographs (UBV, RIZ, YJH) providing a spectral ∼100,000 with minimum simultaneous wavelength coverage 0.4-1.8 µm the goal extending it to 0.35-2.4 addition K band spectrograph. It operates both in seeing- diffraction-limited conditions fibre-feeding allows several,...
The sudden outburst of in-band solar radio noise from the Sun is recognized as one potential Radio Frequency Interference (RFI) sources that directly impact performance Global Navigation Satellite System (GNSS) receivers. On September 24, 2011, active region 1302 unleashed a moderate M7.1 soft X-ray flare associated with very powerful burst at 1415 MHz. Solar Burst (SRB) event spanned over three distinct episodes emission reached maximum flux density 114,144 Flux Units (SFU) 13:04:46 UTC....
The Heliophysics Integrated Observatory (HELIO) is a software infrastructure involving collection of web services, heliospheric data sources (e.g., solar, planetary, etc.), and event catalogues – all which are accessible through unified front end. In this paper we use the HELIO to perform three case studies based on solar events that propagate heliosphere. These include coronal mass ejection intersects both Earth Mars, energetic particle crosses orbit Earth, high-speed wind stream, produced...
The recovery and resilience of the cultural creative sectors after COVID-19 pandemic is a current topic with priority for European Commission. Cultural gems crowdsourced web platform managed by Joint Research Centre Commission aimed at creating community-led maps as well common repository places across cities towns. More than 130,000 physical locations online activities in more 300 towns are currently tracked application. main objective consists raising holistic vision culture, reinforcing...
At the end of 2021, ESO council approved start construction phase for a High Resolution Spectrograph ELT, formerly known as ELT-HIRES, renamed recently ANDES (ArmazoNes high Dispersion Echelle Spectrograph). The current initial schedule foresees 9-years development aimed to bring instrument on-sky soon after first-generation ELT instruments. combines spectral resolution (up 100,000), wide range (0.4 µm 1.8 with goal from 0.35 2.4 µm) and extreme stability in wavelength calibration accuracy...
The accurate long-term forecasting of solar activity is crucial in the current era space explorations and study planetary climate evolution. With timescales about 11 years, these forecasts deal with prediction very general features a cycle such as its amplitude, peak time period. Solar radio indices, continuously measured by network ground-based telescopes, are among most commonly used descriptors to characterise level. They can act proxies for strength ionising radiations, ultraviolet X-ray...
Solar radio observations play an important role in the framework of Space Weather Science and Operations. They represent a powerful diagnostic tool both for investigation coronal plasma forecasting direct impact noise on quality reliability technological systems such as radio-based communications services. To better understand involved physical phenomena effects infrastructures constant monitoring solar emissions is fundamental. In this paper we describe new Italian instrument called Trieste...
