The idea is worth exploring. Cosmic rays can indeed trigger bit flips, and auroras result from particles striking the atmosphere. This connection suggests that increased auroral activity might correlate with a higher risk of bit flips. However, modern storage solutions like SSDs are generally more resistant than traditional hard drives, and CPU or non-ECC RAM can still be affected. It seems wise to avoid downloading data during periods when auroras are prominent.
Don't fret about it. Unless you decide to leave Earth's magnetic field, the odds of bit errors are incredibly low. Many iPads used on the International Space Station work well and handle space-related data issues without problems, even while passing through auroras often.
We're all aware that cosmic rays might lead to bit flips. Did we realize this before? I wasn't aware of it.
Aurora Borealis happens when charged particles move toward Earth along magnetic field lines to both poles. Based on current understanding, cosmic or gamma rays usually don’t follow magnetic paths. This suggests no link between aurora strength and bitflip rates from those high-energy rays. The particles involved are generally low-energy, while cosmic and gamma rays carry much higher energy. Bitflips can indeed occur, leading to errors in CPU registers or DIMM gates when they misfire during write-back. Depending on the affected data, it may corrupt cache writes or trigger a kernel panic. In networking and storage, CRC error correction is used, but its effectiveness varies with data type and location. For greater reliability, servers often employ ECC memory to provide extra protection against faults.

Thanks for the information but that was what I already know. I was concerned that the charged particles hitting the atmosphere release photons (aka Aurora Borealis) can also release higher energy rays and other particles... I know avionics and spaceflight equipment are so expensive because they are hardened to protect against it. While my computer is near a window with a glass side panel. Pretty much like a patient during a open heart surgery... Well I wish there is a dedicated paper on the subject...
There's also a statistical measurable increase in cancer rate among pilots and the rest of the flight crew. Officially, there's no causality, but only correlation. The current theory is that because the atmosphere is much thinner at higher altitudes, cosmic rays strike with more occurrence. Being that it's ionizing radiation, these packets of energy strike DNA strands and shatter the chemistry bonds that hold the atoms together. Cellular repair does happen with DNA that's the equivalent of RAID1 (a pair). But depending on where and how severe along the strand the damage is, transcription errors can occur during the mitosis phase (cellular division). A damaged cell will self-destruct properly. But the cells that go on dividing uncontrollably is by nature "cancer". We all get struck with ionizing radiation every day (no, WiFi or cellular doesn't count as it's the non-ionizing type). It all comes down to probabilities in how ionizing radiation cumulatively effect us.
