What the heck does tonight mean ..

You know, tonight, that specific time of day that happens at the same time every day depending on where you are and what season it is there.

Yeah I was also quite annoyed by that.

I'm more worries that this is described as something coming from the sun and reaching first the part of the planet that is facing away from it.

I always knew the sun was a hoax and the earth is flat. I'm vindicated now.

I don't know a lot about this so maybe the article is still incorrect, but that may not be as ridiculous as it sounds. The magnetosphere isn't a perfect orb surrounding the planet and I thought I recalled hearing that the 'backside' and the poles were the weaker sides.

Given the statement was by the US organization NOAA they probably mean night in North America.

From following a couple links to the source, I found this:

Multiple CMEs erupted associated with flare activity from Region 3664 on 07-09 May. These CMEs are expected to merge with potential arrival expected by early May 11 on the UTC day.
