PRESTO

SCOSTEP is tasked to organize organize long-term scientific programs in solar terrestrial physics. The program for 2020-2024 is Variability and Predictability of the Solar-Terrestrial Coupling (PRESTO). PRESTO was defined based on a community effort with numerous white papers submitted to the Committee for Definition of the Next Scientific Program (NSP) and two fora organized by the International Space Science Institute (ISSI) in Beijing in 2018 and in Bern in February 2019. PRESTO's goals are to "address the predictability of 1) space weather on timescales from seconds to days and months, including processes at the Sun, in the heliosphere and in the Earth’s magnetosphere, ionosphere and atmosphere, [and] 2) sub-seasonal to decadal and centennial variability of the Sun-Earth system, with a special focus on climate impacts and a link to the World Climate Research Program (WCRP) Grand Challenge Near-Term Climate Predictions as well as the IPCC." (NSP Concept Text).

PRESTO Logo Contest Winner Announced

We are pleased to share the results of the PRESTO logo contest. A total of 37 clever designs were submitted for consideration.  After much thought, the PRESTO committee selected the design provided by Mr. Vishal Jagatsing Pawar.  Mr. Pawar is a Master's Degree Candidate in Atmospheric and Space Science at Pune University in Maharashtra, India.

Congratulations to Mr. Vishal Pawar and thanks to all who submitted a design.

PRESTO is comprised of 3 Pillars:

Pillar 1. Sun, interplanetary space, and geospace
Pillar 2. Space weather and the Earth’s atmosphere
Pillar 3. Solar activity and its influence on the climate of the Earth System

SCOSTEP-PRESTO ONLINE SEMINAR SERIES

In response to the current difficulties of hosting meetings in person, SCOSTEP-PRESTO will host online seminars to deliver the latest scientific topics and/or instructive review presentations on solar-terrestrial physics related to SCOSTEP's PRESTO program.

At this time, we are pleased to announce the first seminar. Please register for the seminar using the Zoom registration link below.

Abstract:
Solar flares are catastrophic explosions in the solar corona and may potentially cause a severe space weather disaster. However, because the onset mechanism of solar flares is not yet well elucidated, most of the flare forecasts in operation rely on empirical methods. We recently developed a new physics-based model, called the κ-scheme, for predicting giant solar flares as one of the major outcomes of the Project for Solar-Terrestrial Environment Prediction (PSTEP), which is the Japanese nation-wide project for space weather and space climate study. The κ-scheme is able to predict imminent giant solar flares through the critical condition of magnetohydrodynamic (MHD) instability triggered by magnetic reconnection. An analysis of the largest solar flares in solar cycle 24 indicates that the κ-scheme can provide precise information, including location and size, of possible giant solar flares with a small exception. Through this study, we also discovered that the magnetic twist flux density in the vicinity of the magnetic polarity inversion line (PIL) on the solar surface plays a crucial role in determining when, where, and how large solar flares may occur. Finally, we will discuss how important is the development of physics-based prediction to improve our predictive capability and the scientific understanding of solar-terrestrial system dynamics.
