SYNOPSIS...

A moderately strong solar disturbance impacted the Earth near 18:27 UTC
on 07 November. This disturbance was larger than anticipated and is producing
periods of enhanced auroral activity. More significant storm-level auroral
activity is expected over the next 12 to 18 hours as this disturbance
matures. Widespread observations of auroral activity may be possible tonight.

Another potentially strong disturbance could arrive on 09 November.
Analysis of the solar event is still in-progress. We expect the latter half
of the UTC day of 08 November to be less active and then pick up again when
this next disturbance arrives.

This warning will remain valid through 23:00 UTC (6 pm EST) on
10 November. It will then be updated, downgraded to a watch or allowed to
expire altogether. For updated information, visit:
