GEOMAGNETIC STORM WATCH (G1): NOAA forecasters say that minor G1-class geomagnetic storms are possible on July 13-14 when a stream of solar wind is expected to hit Earth’s magnetic field. The gaseous material is flowing from a northern hole in the sun’s atmosphere. Aurora alerts: SMS Text
I support the existence of SpaceX and Starlink and most of the work Elon does. But I advocate for balance, restraint, and cooperation, which sometimes gets lost in the mix. Que Cera Cera!
SUPERSTORM TRIGGERED A MASS MIGRATION OF SATELLITES: Earth just experienced the biggest mass migration of satellites in history. On May 10, 2024, approximately 5000 spacecraft had to maneuver to maintain altitude, resisting a geomagnetic storm that was trying to pull them down. The event is described in a research paper just accepted by the Journal of Spacecraft and Rockets.
This was the post on my blog that day. Complete synchronicity.

Thus, the Sun and Earth are the boss, not man-made tech, which I keep saying on the platform, but it falls on deaf ears.

“Most were SpaceX Starlink satellites,” says William Parker of MIT, the paper’s lead author. “Each satellite has a GNSS receiver as well as autonomous station-keeping and collision-avoidance capabilities. When they sensed the effects of the storm, thousands of the satellites made the decision to maneuver.”
The need to migrate upward was caused by a sudden increase in satellite drag. Earth’s atmosphere absorbed a huge amount of energy from the solar storm, causing it to puff up like a marshmallow held over a campfire. Tendrils of heated air reached into space and started dragging the satellites down.
“The superstorm’s peak power was 2.63 TeraWatts,” says Martin Mlynczak, who retired from NASA’s Langley Research Center a month after the storm. Before he left, he used infrared data from NASA’s TIMED spacecraft to estimate the amount of thermal energy dumped into the upper atmosphere. “It deposited enough energy to run my house for 10 million years (I average about 510 kWh per month),” he says.
Earth’s atmosphere has been heated this much before, most recently during the Halloween storms of 2003. In those days, however, the satellite population was relatively low (fewer than 1000) and there was no mass migration.

“The May 2024 geomagnetic storm was the first major storm to occur during a new paradigm in low Earth orbit satellite operations dominated by commercial small satellites,” the authors wrote in their paper.
Thanks mainly to the advent of Starlink in 2019, Earth now has almost 10,000 active satellites–ten times the number in 2003. When a fraction of them unexpectedly decide to change course all at once, satellite operators must scramble to track them, making sure they don’t collide. This creates a new and unprecedented risk for all satellites, even ones that don’t move.
It’s a problem that will only get worse in the years ahead. “Major storms are more likely throughout 2024-2025 during the peak of Solar Cycle 25,” says Parker, “and the satellite population continues to grow.”
(IMO, Elon needs to curb the number of satellites he sends up, but he doesn’t listen to me. I thought I was willful, which I am. We need a new word for willful with him.-L.T.)
