The GOES satellites run on solar power, and have a limited battery capacity. So for a couple of months around each equinox, when they are eclipsed by the Earth, there are a couple of hours each night of no imagery.

Good question ... I don't remember offhand, but I think it's round-about a month on each side of the equinox ... getting shorter the further from the equinox you get.

I believe it lasts for a few weeks and during that there is no way to get satellite imagery.

This satellite "blackout," usually called a satellite eclipse.

It has been occurring between 11:45 PM and 2:45 AM Eastern (345Z to 645Z)... for those that didn't know.

I just did a search to find this topic,

what time tonight is the satellite blackout ?

Thanks for being psychic ;)

BUt the nice thing is we have radar..so we still will have a pretty good idea about what the eye is doing....bad thing is...obviously having radar means it's too close to where any of us want to see it :(

Does anyone know the link for the satelitte that isn't affected by the eclipse?

A couple of weeks ago someone posted about this satelitte. (If I remember correctly, they said the images were in B&W)
