The SolarMonitor Migration

The SolarMonitor Migration: A New Dawn for Solar Data Access

After more than two decades of service to the heliophysics community, SolarMonitor is entering a new era. The aging infrastructure of SolarMonitor (SM) is being replaced by a powerful, flexible, and modern platform: SolarMonitor2 (SM2).

This transition is more than just a facelift — it's a re-engineering of how solar data is delivered, accessed, and utilized. And to ensure a smooth experience for users, the migration will take place in three clear phases from May 2025 through January 2026.

🌞 Phase 1: May – August 2025

Goal: Introduce users to SM2 while maintaining full access to SM.

  • solarmonitor.org will continue to point to the current SolarMonitor (SM), but a banner will be added to every page announcing the upcoming changes and inviting users to explore the new system.
  • test.solarmonitor.org will serve as the preview site for SM2, offering access to the updated interface, enhanced data offerings, and API documentation.

This phase is all about transparency, stability, and giving users time to adapt.

🚀 Phase 2: September – December 2025

Goal: Transition SM2 as the primary platform while preserving legacy access.

  • solarmonitor.org will now redirect to SolarMonitor2, officially making SM2 the main entry point for users.
  • old.solarmonitor.org will be created to preserve access to the original SolarMonitor for those who still need legacy tools or data formats.

This phase ensures continuity while encouraging full adoption of the new system.

🌐 Phase 3: January 2026 and Beyond

Goal: Complete migration and streamline access.

  • The original SolarMonitor (SM) will be shut down, and all legacy URLs will be permanently redirected to SM2 at solarmonitor.org.

With SM2 fully live and maintained, users will benefit from modern features, faster performance, and expanded data access — all from one streamlined portal.

Why This Matters

SolarMonitor2 isn't just a newer version — it's a complete rethinking of how solar data is processed, visualized, and shared: - Faster, cleaner UI - Expanded data sources and higher update cadence - Programmatic API access - Modular, container-based architecture built for the future

The transition is designed to be as seamless as possible, with thoughtful steps to keep the community informed and supported at every stage. Whether you're a long-time user or discovering SolarMonitor for the first time, now is the perfect time to explore what SM2 has to offer.
