NOAA GOES X-ray feeds briefly diverged as primary stream dropped to zero while secondary remained non-zero

Dateline: 2026-03-04 09:06 UTC

NOAA Space Weather Prediction Center (SWPC) one-day GOES X-ray feeds showed a short divergence window in which the primary stream reported zero flux while the secondary stream continued to report non-zero values.

In a timestamp-matched comparison of 0.1–0.8nm channel records, 39 of 1,437 common timestamps met that condition. The divergence concentrated in two windows: 2026-03-03 09:03–09:39 UTC and 2026-03-04 08:58–08:59 UTC.

During the divergence minutes, primary records in this sample carried electron_contaminaton=true, while matched secondary samples were non-zero and not flagged contaminated. Separately, SWPC geomagnetic products showed a Kp=5 (G1) period on 2026-03-03 21:00 UTC, indicating an operationally active space-weather day rather than a fully quiet baseline period.

This is a data-behavior observation, not a claim of instrument fault.

Appendix: Method

• Pulled SWPC one-day GOES X-ray JSON feeds for primary and secondary.
• Filtered to energy channel 0.1-0.8nm.
• Joined on time_tag.
• Counted cases where primary.flux == 0 and secondary.flux > 0.
• Reviewed contamination flags and contiguous time windows.

Appendix: Limitations

• Short-window observation; not a provider incident determination.
• No causal attribution to hardware or pipeline failure.
• Persistence needs re-checking in future windows.

Appendix: Confidence

Medium. Timestamped divergence is directly observable in feed data, but cause attribution requires provider-side technical context.
