A powerful geomagnetic storm transpired over the Lower-48 during the weekend of 11-13 May 2024. The sun produced coronal mass injections that impacted the Earth, creating auroras (a.k.a., northern lights) that were seen across the globe. Within CONUS, the auroras were visible as far south as Florida, Texas, and Alabama: locations where the northern lights are typically Continue Reading

During March 2024, NOAA-21 was declared the primary satellite of the Joint Polar Satellite System (JPSS). In early April 2024, NOAA-20 (newly designated as the secondary satellite) completed its orbital shift placing NOAA-20 a half-orbit (~50 minutes) a part from NOAA-21. The tertiary satellite, SNPP, is now positioned a quarter-orbit between NOAA-21 and NOAA-20. A Continue Reading

During mid-April 2024, unprecedented flooding occurred in the Middle East, specifically in the countries of the United Arab Emirates (UAE) and Oman. Over the course of a few days, a series of storms produced significant precipitation totals that pummeled the region, which led to extensive flooding that shut down schools, grounded or diverted flights, and Continue Reading
