Solar Orbiter, the first mission of ESA's Cosmic Vision 2015-2025 programme and a international collaboration between ESA NASA, will explore Sun heliosphere from close up out ecliptic plane. It was launched on 10 February 2020 04:03 UTC Cape Canaveral aims to address key questions solar heliospheric physics pertaining how creates controls Heliosphere, why activity changes with time. To answer these, carries six remote-sensing instruments observe corona, four in-situ measure wind, energetic...
Abstract Launched on 12 Aug. 2018, NASA’s Parker Solar Probe had completed 13 of its scheduled 24 orbits around the Sun by Nov. 2022. The mission’s primary science goal is to determine structure and dynamics Sun’s coronal magnetic field, understand how solar corona wind are heated accelerated, what processes accelerate energetic particles. returned a treasure trove data that far exceeded quality, significance, quantity expectations, leading significant number discoveries reported in nearly...
Abstract On 2022 February 15, an impressive filament eruption was observed off the solar eastern limb from three remote-sensing viewpoints, namely, Earth, STEREO-A, and Solar Orbiter. In addition to representing most-distant at extreme ultraviolet wavelengths—captured by Orbiter's field of view extending above 6 R ⊙ —this event also associated with release a fast (∼2200 km s −1 ) coronal mass ejection (CME) that directed toward BepiColombo Parker Probe. These two probes were separated 2° in...
Analysis of MESSENGER magnetic field observations taken in the southern lobe Mercury's magnetotail and adjacent magnetosheath on 11 April 2011 indicates that a total 163 flux transfer events (FTEs) occurred within 25 min interval. Each FTE had duration ∼2–3 s was separated time from next by ∼8–10 s. A range values have been reported at Earth, with mean near ∼1–2 ∼8 min, respectively. We term these intervals quasiperiodic “FTE showers.” The northward sunward orientation interplanetary during...
In this Letter, we present the first direct detection of a rotating coronal mass ejection (CME) in middle corona (5-15 R ?). The CME rotation rate is 60? day-1, which highest reported yet. Earth-directed event was observed by STEREO/SECCHI and SOHO/LASCO instruments. We are able to derive three-dimensional morphology orientation flux rope applying forward-fitting model simultaneous observations from three vantage points (SECCHI-A, -B, LASCO). Surprisingly, find that even such rapidly does...
Abstract The Wind spacecraft, launched on November 1, 1994, is a critical element in NASA’s Heliophysics System Observatory (HSO)—a fleet of spacecraft created to understand the dynamics Sun‐Earth system. combination its longevity (>25 years service), diverse complement instrumentation, and high resolution accurate measurements has led it becoming “standard candle” solar wind measurements. over 55 selectable public data products with ∼1,100 total variables (including OMNI products)...

(2) How do transients drive...

In particular, investigate parallel perpendicular cross section expansion from corona through heliosphere...

The process by which the Sun affects terrestrial environment on short timescales is predominately driven amount of magnetic reconnection between solar wind and Earth's magnetosphere. Reconnection occurs most efficiently when field has a southward component. severe impacts are during arrival coronal mass ejection (CME) magnetosphere both compressed magnetically connected to heliospheric environment. Unfortunately, forecasting vectors within ejections remains elusive. Here we report how,...
