TUCSON, AZ—Officials at the Kitt Peak National Observatory are saying that, while the short period of utter darkness and intense cold was distressing, there is "no immediate cause for alarm" over the sun's six-second outage Monday. "We're not sure what caused our sun, which is in essence a self-sustaining fusion reaction, to defy science and just go out for a moment like that, but I wouldn't worry too much," astronomer Stephen Pompea said. "There is a slight chance it could repeat, like sunspot activity, a more common—whup! There it goes again. You seeing this? Kind of weird how it—okay, back on." Observatory personnel said they would give their full attention to investigating the phenomenon as soon as they figure out why last night's moon was blood red and took up half the sky.
