Track the Planetary K-index

Collect and chart NOAA planetary K-index readings without hand-parsing header-array JSON. The NOAA Space Weather Scraper provides a bounded connector to the authoritative publisher while preserving stable identifiers and source URLs on every row.

Start with a small, reviewable query

{"product":"planetary_k_index","maxResults":250}

Run a small sample before expanding the result limit. Inspect identifiers, dates, null values, units, qualifiers, and source fields in the Apify Dataset. Export as JSON for nested fields or CSV and Excel for review. For recurring ingestion, upsert on the publisher stable record dimensions instead of assuming every run is append-only.

Build a reliable data pipeline

The Actor uses direct HTTP requests, bounded inputs, transient-error retries, and explicit empty-result failures. It does not require a browser or paid proxy, so scheduled runs remain inexpensive. Keep the input in an Apify Task, send completion through a webhook, and load the dataset into a warehouse or dashboard. Store collection time downstream so source revisions can be distinguished from newly published records.

Interpret the source responsibly

Official publication does not remove the need for context. Preserve footnotes, status fields, dataset type, reporting period, and source attribution. A missing value is not zero, and a revised record is not necessarily a new event. For legal, medical, financial, safety, protection, or public-policy decisions, confirm material findings with the publisher and a qualified specialist.

This workflow is designed for space-weather researchers, infrastructure teams, and science educators. It is an independent integration and is not affiliated with or endorsed by the source institution.

Interpret Kp as a time-binned index

The planetary K index summarizes geomagnetic disturbance over defined intervals; it is not a continuously measured local field value. Keep the observation timestamp, reported Kp, product status, and any forecast or estimated designation together. Plot stepwise intervals rather than smoothing them into artificial precision. If the feed contains measured, estimated, and predicted values, give each a distinct style and never merge them without a label. A scheduled Task can append new intervals and revise the latest provisional row when NOAA updates it. Compare Kp with operational thresholds only using the definitions published by SWPC.
