At 11:00 AM, it was 45°F in Champaign, with an ESE wind at 14 mph and heavy fog with vertical visibility of less than 200 feet.
Although the fog is expected to dissipate, the cloud ceiling is not forecast to rise above 600 feet during our launch window, and wind gusts up to 23 mph are predicted.
Therefore, today's launch is canceled.
We'll try again on Wednesday (January 1) and again on Saturday, January 11.
