NOAA has upgraded its geomagnetic storm watch to G2 as merged solar blasts approach Earth, raising the odds that the aurora may be visible across as many as 20 U.S. states on Wednesday. The upgrade follows a rare proton burst that originated from a sunspot‑free solar region, prompting the agency to issue a minor storm watch earlier and to alert the public to heightened geomagnetic activity.

Nature World News detailed NOAA’s G2 upgrade and the underlying proton burst, while Forbes highlighted the potential for a 20‑state aurora display on Wednesday. Regional outlets such as The Sun, KMOV, krem.com and Northern News Now focused on tonight’s viewing chances, describing the event as visible to a handful of lucky states and offering location guides for observers.

The combined coverage underscores both the scientific significance of the solar activity and its immediate visual impact for the public. Watchers should follow NOAA’s real‑time alerts for any further upgrades to the storm watch as the solar blasts continue to track Earth.
