I haven't been checking weather sites as frequently lately (something about it being cold), but today I was poking around and realized the satellite image sources on some of NOAA's sites have either changed, or are not there anymore. I looked into why and found this.

It turns out that there is a change for GOES-East. The GOES-13 satellite has been retired and is replaced by GOES-16. What this means is any of your favorite weather sites that use GOES-East images may have been impacted by a change in source data.

What it ALSO means is... we've got awesome new satellite images.

GOES-16 Drift and Transition to Operations

I like these from College of DuPage

U of Wisconsin-Madison has a good page too

Those are great. I have a long list of bookmarks going. Those aren't on my list yet.

I see Penn State is still using GOES-13... or at least images that are labeled as GOES-13.

Those are amazing images....

It's GOES, not GEOS. Geostationary Operational Environmental Satellite. Pardon me for being so picky.

Thanks. I have fixed the original post. Can you tell I once had a Commodore 64?

GOES 16 is awesome for astronomy weather prediction. But if you think of Earth as an astronomical observing target check out the full disk views on the geocolor polychromatic channel! If you like the earth images from the EPIC camera on the DSCOVR spacecraft you will go nuts for these. GOES is geostationary by definition so you can't see the earth rotate like you do with the EPIC images but you do get to see the sunrise and sunset terminators move across the disk in insane detail. One thing you get with the new geocolor channel that you don't get with the old satellites is surface illumination under clear night skys. So you also get a feel for inhabitation and light pollution similar to some of the imagery from the ISS but for a full disk.

Yes, the EPIC images are awesome. Eclipses and moon transits are worth checking out in their historic images.

I also agree, the GOES images are much better at night than they used to be from the old satellite. The GeoColor is very handy so you don't have to switch from VIS to IR when it gets dark. It's fun to watch the cut-off line between images swipe across on the 96 image loop.

You seem to be good at assembling telescopes. I have a Apogee 8" f4 i got at a yard sale. I really want to get it working. The mirror isn't installed but I have all the screws and springs. I really don't know what I'm doing and I don't want to damage anything. Do you think it's possible for you to help or guide me?

Thanks,
Reed

Yes Reed, I would be glad to help. Let's set up a time. I'm retired so my calendar is pretty much open.
