NOAA Aircraft Ops Center on Instagram: "As Hurricane #Erin became the first hurricane of the 2025 Atlantic hurricane season, our crews were collecting critical data to help refine the forecast and support hurricane research. Take a look at our mission highlights! 🕑 111+ hours flown ✈️ 18 missions flown across #NOAA42 #NOAA43 and #NOAA49 ⬇️ 333 dropsondes and 40 airborne expendable bathythermographs deployed #FlyNOAA"

The NOAA model run includes the two Earth-directed #solarstorm launches. The larger one catches up with the smaller one just ahead of Earth so a precursor disturbance may indeed ramp up before the larger storm hits. Impact is expected by late September 1. G2 conditions are possible, which means aurora may be visible at mid-latitudes, despite a bright moon. | Space Weather Woman
