For what it’s worth, I have the following qualitative information to share regarding the Illinois flash and this morning’s meteor activity.
I have used radios to monitor meteor activity over the Western United States for many years. The method is simple; a radio detects meteors by monitoring a distant (usually over-the-horizon) radio transmitter that is normally unheard. When a meteor burns up between the receiver and transmitter, the ionization trail it leaves behind briefly reflects the transmitters signal to the receiver. More information about this method is found in the links below.
After reading this posting I tuned my meteor monitoring equipment to 67.251 MHz** LSB***, a television station in Mexico some 2400 km from my location in North-Central Colorado. This separation distance limits detection to larger meteors that leave a high altitude ionization trail above 100 km. For the 1 hour period between 2:30 AM to 3:30 AM CDT this morning (1 hour after the flash) I heard the typical sounds from 2 abrupt reflection events (mostly likely small meteor ionization events) and 1 diffuse reflection event (most likely a very tiny meteor). This is atypical for this time of night (meteor events usual peak in the hour before and after sunrise). More activity that is atypical was heard during the subsequent 1 hour window from 3:30 AM to 4:30 CST.
Three events within a 1-hour window may not sound impressive, but the unfavorable time of day, the unfavorable 2400 km separation geometry****, and the unfavorable time of year during the very low intensity Aquarids meteor shower makes these events significant. These results support the POSSIBILITY, among many others, that the Illinois flash was a meteor entry event.
**67.251 MHz = 1 kHz above the video carrier frequency for analog TV channel 4
***LSB = Lower Side Band
****At 2400 km separation between the receive and transmit antennas their respective patterns will overlap 115 km above earth, much higher than the typical meteor ionization trail range between 75 km and 100 km above earth

Just saw a thread on here regarding the Sunspots and CME's I'm pretty sure that is what caused the interference and so called Power outages over parts of the world. But I can't be 100% sure all I know is that we were expecting some CME's and there are still huge Sunspots spotted on the sun at the moment. Hopefully this might answer your question. But then again you're posting on here so really I'm not sure haha.

STRONG SOLAR ACTIVITY: On Saturday morning, Sept. 24th, behemoth sunspot 1302 unleashed another strong flare--an X1.9-category blast at 0940 UT. NASA's Solar Dynamics Observatory recorded the extreme ultraviolet flash:
