Preface: In 1901, engineer Nikola Tesla made the astonishing claim that he was receiving radio communications from Mars. His description was picked up and reported on broadly in the press.

Background: Solar flares are a regular part of the solar cycle, which lasts about 11 years on average. In 1901, a major solar event was observed that was not a large storm, but a “huge solar disturbance” with visible Sunspots, bright spots and distinctive coronal disturbances.
A coronal disturbance, often in the form of a coronal mass ejection (CME), is a significant eruption of plasma and magnetic field from the Sun’s outer atmosphere, or corona. These disturbances can propagate through space and, if directed towards Earth, can cause geomagnetic storms and other space weather phenomena.
Ref: Geomagnetic storms, disturbances in Earth’s magnetic field caused by solar activity, can impact our planet in various ways, primarily affecting technology and infrastructure. While not directly harmful to humans due to our planet’s protective magnetic field and atmosphere, they can disrupt communication systems, navigation, and power grids.
Do you think Nikola Tesla encountered a solar flare 124 years ago? Or was the radio communication sent from Mars?
There was a large solar flare in April 1901, specifically on April 21, which was associated with bright faculae. This event was noted by observers and is possibly linked to a short-lived sunspot group. However, the more commonly referenced “huge solar disturbance” from 1901 is related to Nova Persei 1901, a bright nova that appeared in February 1901 and reached its peak brightness in September. The bright patch of faculae in April was likely a separate event.
Do you want to know what the solar flares are like this week?
In June 2025, NASA’s PUNCH mission (Polarimeter to Unify the Corona and Heliosphere) captured detailed images of coronal mass ejections (CMEs) as they erupted from the Sun. Additionally, NASA’s Solar Dynamics Observatory (SDO) observed a strong solar flare on June 17, 2025.
