1/5 Prioritize Safety: Ensure both your eyes and camera are protected with appropriate solar filters. Never look directly at the total solar eclipse without proper eye protection. Use a solar filter for your camera lens to prevent damage. Remember to remove the filter during totality to capture the Sun's corona safely. (NASA)

2/5 Utilize Available Equipment: Regardless of your camera type, whether a DSLR or a smartphone, focus on honing your skills and creativity. Even basic equipment can produce stunning results. If lacking specialized gear like a telephoto lens, opt for landscape shots to capture the ambiance of the changing light. (NASA)

4/5 Explore Diverse Perspectives: Beyond capturing the eclipse itself, seize the opportunity to document the surrounding environment. Look for unique lighting effects, shadow play, and the reactions of fellow eclipse watchers. Embrace different angles and viewpoints to add depth to your photography. (NASA)

5/5 Master Your Gear: Familiarize yourself with your camera's settings well ahead of the total solar eclipse. Experiment with exposure and focus to adapt swiftly to changing light conditions during the eclipse. Practice adjusting settings for optimal results, particularly during the transition from partial to total eclipse phases. (NASA)

Earth faces a severe G4 geomagnetic storm, potentially disrupting radio communication, according to a recent NOAA alert. (Unsplash)

In a recent alert from the National Oceanic and Atmospheric Administration (NOAA), Earth experienced a severe G4 geomagnetic storm on Sunday, indicating potential disruptions to radio communications. The NOAA emphasised that while the storm may fluctuate in intensity, ranging from lower levels to severe conditions, there's no need for panic among the public. However, staying informed about the storm's progression via NOAA's webpage is encouraged. This phenomenon was declared as the strongest solar storm since 2017!

The NOAA's alert notifies infrastructure operators to take mitigating actions against possible impacts, including increased voltage control problems and potential effects on satellite operations. The severity of the storm, hitting the G4 level on the NOAA's 5-point scale, arrived earlier than anticipated, reaching its threshold at 16:28 UTC.

Potential Impact on Communication Systems

Jonathan Lash, a forecaster at the center, highlighted potential impacts on high-frequency radio transmissions, particularly those crucial for aircraft communication with distant traffic control towers. While most commercial aircraft have satellite transmission as a backup, satellite operators may face challenges in tracking their spacecraft, and power grids might experience induced currents in their lines, although within manageable levels.

Skywatching Opportunity Amidst the Storm

Lash also pointed out a silver lining for skygazers, especially those at higher latitudes,

suggesting that clear night skies during geomagnetic storms offer an excellent opportunity to witness the aurora borealis illuminating the heavens.

Geomagnetic storms, such as this one, have the potential to create dazzling displays of the aurora borealis over the Northern Hemisphere. Before the storm's arrival, satellites detected solar flares and coronal mass ejections emitted from the Sun on Friday, contributing to the atmospheric disturbance.

What is a coronal mass ejection?

For those unfamiliar with coronal mass ejections, NASA describes them as massive bubbles of coronal plasma propelled by intense magnetic fields ejected from the Sun over several hours. Often resembling twisted ropes, these phenomena accompany solar flares or explosions on the Sun's surface.
