A April 23rd Magnetosphere Anomaly

AI Thread Summary
On April 23, 2016, an anomaly in the magnetosphere was observed, potentially linked to solar wind effects from a coronal hole on the sun. The interplanetary magnetic field was thought to be pointing north, but solar particles may have briefly flipped it south, causing a temporary cancellation of Earth's magnetic field. The full moon and its apogee coincided with this event, raising questions about its impact. Previous occurrences of similar anomalies have not led to significant consequences, typically resulting in minor effects like changes in auroral activity or cosmic ray penetration. Overall, the discussion highlights the ongoing monitoring of solar activity and its implications for Earth.

At that time the solar wind was having an effect on Earth due to a stream flowing from a coronal hole on the sun. The interplanetary magnetic field was supposedly pointing north at the time. But perhaps the solar particles briefly turned the field south, causing a brief cancellation of Earth's magnetic field? Curiously, the moon was full and at apogee at vaguely the same time.From the April 22 edition of spaceweather.com:

A gaseous canyon in the sun's atmosphere has turned toward Earth, and it is spewing solar wind in our direction. NASA's Solar Dynamics Observatory is monitoring the structure, shown here in an extreme ultraviolet image taken on April 22nd:

Thanks for your answer, I am curious has this happened before? What are some potential outcomes?

I'm no expert. But I'm sure this or something quite similar has happened very often, with no particularly alarming outcomes or consequences I'm aware of. Probably auroral activity or penetration of cosmic rays to Earth's surface is briefly affected.
