Here's our local noon composite for #EarthDay made from 5 geostationary imagers (2 USA, 2 EUMETSAT, 1 JMA). Where were you at noon? Unless you were off planet or in the arctic/antarctic circle, you must be in this image somewhere! About local noon images: ssec.wisc.edu/data/composite…

Now that the sun has set on the @NOAASatellites #GOESEast subpoint, here is an animation from sunrise to sunset for #EarthDay with the "CIMSS Natural Color" enhancement:

We did not forget that today is #EarthDay! Here is @NOAASatellites #GOES19 Full Disk at local satellite noon. More images and animations will be added to this CIMSS Satellite Blog post: cimss.ssec.wisc.edu/satellite-blog…

The @NWSSPC mesoscale discussion: spc.noaa.gov/products/md/md… and our realtime GOES-East imagery combined with our rooftop cameras website: cimss.ssec.wisc.edu/goes/rtc_goes_… and @NWSMilwaukee issued thunderstorm and special marine warnings this afternoon. Stay safe!

From @NWSSPC: A small cluster of elevated tstorms has persisted into early afternoon in SE WI, aided by forcing for ascent attendant to an upstream shortwave trough. This animation shows what we saw from @NOAASatellites #GOESEast and our rooftop cameras as it appeared overhead.

1-minute @NOAASatellites #GOESEast Infrared images with plots of 1-minute GLM Flash Points show lightning activity in the general vicinity of Pewaukee, Wisconsin during the 10-minute period leading up to the reported time of the fatality (0043 UTC). #WIwx cimss.ssec.wisc.edu/satellite-blog…

There is a 1-to-1 dollar match up to the first $10,000 donated. Check out last year's 5 student recipients of the Suomi Scholarship: ssec.wisc.edu/news/articles/…

There's about 1 hour left to donate to our #DayoftheBadger fundraiser for scholarships for high school seniors going to a UW school. More on last year's recipients in the comments. You can donate here: dayofthebadger.org/campaign/space…

1-min @NOAASatellites #GOESEast Visible images with time-matched @NWSSPC Storm Reports show T-storms that produced tornadoes & large hail (up to 3.25" diameter) & damaging winds (88 mph) across S Wisconsin, far NE Iowa & far SE Minnesota Tuesday 4/14. cimss.ssec.wisc.edu/satellite-blog…

It begins! The 2026 #DayoftheBadger is a spirited 1848-minute event to support students and future scientists at SSEC and @UWCIMSS. Thanks to a generous donation, your gift will be matched dollar-for-dollar up to $10,000: dayofthebadger.org/campaign/space…

2.5-minute @JMA_kishou #Himawari9 Infrared images showed Typhoon #Sinlaku as it made landfall over the islands of Saipan (station identifier PGSN) and Tinian in the Mariana Islands, at Category 4 intensity on April 14, 2026. cimss.ssec.wisc.edu/satellite-blog…

2.5-minute @JMA_kishou #Himawari9 Infrared images showed Super Typhoon #Sinlaku after it had rapidly intensified to a Category 5 storm (as of 1200 UTC on 12Apr2026), southeast of Guam and the Mariana Islands. cimss.ssec.wisc.edu/satellite-blog…

See @NOAASatellites #GOESWest (#GOES18) #GLM data captured the bright signature of the @NASA #ArtemisII #Orion capsule as it re-entered the Earth's atmosphere over the East Pacific Ocean.

1-minute Visible images with GLM Flash Points and the Fire Mask derived product from @NOAASatellites (#GOES19) captured 2 lightning-ignited wildfires (which produced small smoke plumes) in Oldham County, Texas (northwest of Amarillo) on April 9, 2026. @NWSAmarillo #TXwx

True color images from @NOAASatellites #GOESEast showed the hazy smoke associated with prescribed burning across the Flint Hills of Kansas and Oklahoma on April 6, 2026. More on the CIMSS Satellite Blog: cimss.ssec.wisc.edu/satellite-blog…

The #ArtemisII launch/plume could be seen by every spectral band of the @NOAASatellites #GOES19 ABI. More on the CIMSS Satellite Blog: cimss.ssec.wisc.edu/satellite-blog…

Here's the #artemis II launch on April 1, 2026 from @NASAKennedy as seen by @NOAASatellites GOES-19 30-second MESO imagery from 6:25 to 7:25EDT in true color as the sun set on Florida. More on the CIMSS Satellite Blog: cimss.ssec.wisc.edu/satellite-blog…

Congrats @NASA for the successful launch of #Artemis II from @NASAKennedy on April 1, 2026! You may have had a closer seat, but @NOAASatellites GOES-19 saw it from ~22,000 miles away. Here is the "rocket plume" RGB from 30-sec imagery. More on the Blog: cimss.ssec.wisc.edu/satellite-blog…

On Saturday 3/28 you may have missed these vertically-propagating standing wave clouds over northeastern South Dakota. As seen by @NOAASatellites #GOES19 true color visible imagery generated by @UWSSEC CSPP GeoSphere. More on the Blog: cimss.ssec.wisc.edu/satellite-blog…

The large eye of Cyclone #Narelle in 2.5-minute @JMA_kishou #Himawari9 Infrared images as it approached North West Cape in Western Australia. It's a Category 4 again, like when we blogged about it 8 days ago! cimss.ssec.wisc.edu/satellite-blog…
