La NASA invita a la prensa a la primera prueba de defensa planetaria

Tuesday, 23 August 2022

La misión Prueba de redireccionamiento del asteroide doble (DART, por sus siglas en inglés) de la NASA, la primera en el mundo que pone a prueba una tecnología para defender a la Tierra de posibles peligros de asteroides o cometas, impactará con su objetivo, un asteroide que no supone ninguna amenaza para la Tierra, a las 7:14 pm EDT del lunes 26 d

Solar Activity
Solar activity reached high levels. Five sunspot groups were present on the visible solar disk and background X-ray flux levels were mostly in the low C-class levels. Region 3654 (S07W70, Fkc/beta-delta) weakened a bit in its magnetic complexity, as the gamma configuration appeared to diminish. Still the mixed polarity delta spot in the intermediate section retained its magnetic shear and the instability was evident as it produced an M9.5/2b flare at 30/2346 UTC and a long duration C5.8 at 01/0758 UTC. An associated CME was observed with the long duration C5.8 flare. Analysis is ongoing of this event, but due to its far west location, an Earth-directed component is unlikely.
Solar Wind
The solar wind environment was indicative of a slow regime, until near 30/1130 UTC when a disturbance in the field occurred. Total IMF increased from ambient levels and peaked at 14 nT, while the Bz component underwent a prolonged southward deflection with a maximum negative deviation of -8 nT. Solar wind speed underwent a slight escalation, but peaked ~425 km/s. The phi angle varied between sectors, but seemed to settle into primarily a negative sector halfway through the period. While its uncertain what the cause of the disturbance was, a possible candidate was an isolated negative polarity CH HSS that may be flowing just north of Earth or causing weak, tenuous influences or it could also be a transient passage.
Energetic Particle
The greater than 2 MeV electron flux was normal to moderate and the greater than 10 MeV proton flux remained at background.
