A solar event monitored by NOAA could make the northern lights visible across parts of the United States. At this time of year, darkness arrives later and lasts for fewer hours across northern states, reducing the amount of time available to search the sky. The agency’s latest forecast map shows the auroral zone extending into parts of the northern United States. In the continental United States, the potential viewing area stretches across northern states located close to the Canadian border. Northern states will experience shorter nights compared with autumn or winter, leaving observers with a smaller window to search for the aurora.
