solar flares

On June 20, 2023, NASA’s Solar Dynamics Observatory captured the Sun emitting a robust solar flare. The flare reached its peak intensity at 1:09 p.m. EDT on that day.

A solar flare refers to a sudden and significant increase in brightness near the surface of the sun, typically occurring around a sunspot group. These flares involve the violent eruption of high-energy particles and gases from the sun’s magnetic field into space. Solar flares release an enormous amount of energy, ranging from the equivalent of ten million hydrogen bombs to a billion hydrogen bombs.

The specific classification of this flare is X1.0, denoting an X-class flare, which represents the most intense type. The number provides further information about the strength of the flare.

Measuring Solar Flares

Solar flares are measured based on their x-ray intensity in proximity to the Earth. The National Oceanic and Atmospheric Administration (NOAA) categorizes solar flares into three groups:

  1. X-class flares: These are significant events that can trigger planet-wide radio blackouts and long-lasting radiation storms.
  2. M-class flares: These are medium-sized flares that can cause brief radio blackouts affecting Earth’s polar regions. Minor radiation storms may follow an M-class flare.
  3. C-class flares: These are small flares with minimal noticeable consequences on Earth.

Each class represents a tenfold increase in intensity from the previous one. Hence, an X-class flare is ten times stronger than an M-class flare and 100 times stronger than a C-class flare.

Effects of Solar Flares on Earth

Solar flares can have various impacts on Earth, including:

  1. Disruption of Radio Communication: Solar flares can interfere with the Earth’s magnetic field, leading to disturbances that affect radio and GPS signals. This interference can cause blackouts and navigation issues.
  2. Geomagnetic Storms & Aurora: If a solar flare is accompanied by a coronal mass ejection (CME), a massive release of solar wind and magnetic fields into space, it can result in geomagnetic storms. These storms can induce electric currents in power grids, potentially causing power outages. However, they also create captivating auroras, known as the Northern and Southern Lights.
  3. Radiation Risk: Solar flares emit high levels of radiation that pose a risk to astronauts in space and passengers on high-altitude flights. Electronic systems on satellites and spacecraft are also vulnerable to these radiation levels.
  4. Satellite Impact: The high-energy particles emitted during a solar flare can damage satellites, leading to malfunctions or data loss.

It is crucial to note that Earth’s magnetic field and atmosphere provide protection to humans on the ground from the harmful effects of solar flares. However, space-borne technology and astronauts are the primary concerns. In the case of an exceptionally strong solar flare, the consequences could be more severe. Consequently, space weather monitoring organizations closely monitor solar activity.

NASA’s Solar Dynamics Observatory

Launched in February 2010, NASA’s Solar Dynamics Observatory (SDO) is a dedicated mission for studying the Sun. It aims to enhance our understanding of the Sun’s influence on Earth and near-Earth space by observing the solar atmosphere in small scales of space and time and across multiple wavelengths simultaneously.

The primary objectives of the SDO mission include:

  1. Solar Interior Dynamics: Understanding the interior of the Sun and the generation and structure of its magnetic field through helioseismology, which involves studying the sun’s oscillations.
  2. Magnetic Field: Investigating the release of the Sun’s magnetic field into the heliosphere (the space surrounding the Sun) and geospace, including solar wind, energetic particles, and variations in solar irradiance.
  3. Solar Energy Release: Examining the sources of solar variability that impact life and society. This includes studying the conversion of magnetic energy to the kinetic energy of solar wind, the radiant energy of light and heat, and the magnetic energy in solar flares and mass eruptions.

The SDO incorporates various instruments, such as:

  1. Helioseismic and Magnetic Imager (HMI): It examines oscillations and magnetic fields at the solar surface or photosphere.
  2. Atmospheric Imaging Assembly (AIA): It captures images of the solar atmosphere in multiple wavelengths to establish links between surface and interior changes. It provides data in 10 wavelengths every 10 seconds.
  3. Extreme Ultraviolet Variability Experiment (EVE): It measures the Sun’s ultraviolet brightness, which is a significant energy source affecting the Earth’s atmosphere and climate.

The SDO is part of NASA’s Living With a Star (LWS) Program, which aims to comprehend the Sun and the Earth’s space environment in relation to life and society. The near-real-time data continuously transmitted by the SDO has revolutionized our understanding of the Sun and its impact on our planet.
