Presents low-frequency field logs around severe-weather events, acknowledges unresolved sources and confo…

Two logs from one fixed Chicago station bracket the July 27 and Aug. 11, 2026 wind events. They do not record those storms. They record ELF magnetic flux density well above the station baseline and leave artificial induction of ELF unexcluded. HHS is asked to treat the pair as environmental-exposure evidence under Q14 and Q18, and with NOAA to test whether artificially induced ELF was present and bears on severe weather that destroyed homes, leveled trees, and cut power in the Chicago/Indiana region. The logs do not establish weather modification or any causal link. They are the reason to test that possibility against lightning-network data and any ELF records from the days before the damage. Meter: Tenmars TM-192D, triaxial AC, stated passband 30-2000 Hz. It misses the static geomagnetic field and the Schumann fundamental near 7.83 Hz. Same indoor window-adjacent setup. Baseline 0.12-0.15 uT. Ratios use 0.15 uT. July 15-20, before the storms (one photo per sampled day; July 17 and 19 missing): July 15 21:38: 0.334 uT (2.2x). July 16 20:09: 0.468 (3.1x). July 18 ~09:06: 0.598 (4.0x); reported day max 1.60 (10.7x), not a separate photo. July 20 22:12: 0.847 (5.6x); reported day max 2.38 (15.9x), not a separate photo. Photos climb ~0.33, 0.47, 0.60, 0.85 uT (step ratios ~1.4, 1.3, 1.4). "Doubling every day" is the climb against the old baseline, not a factor of two between photos. The rise coincided with Canadian smog. No mechanism or causal link is claimed; no paired air-quality data; wiring not surveyed. Between the logs, NWS Chicago describes two fatal wind events 16 days apart. This station was not logging those mornings. July 27: supercell to compact bow echo; estimated gusts 80-105 mph in parts of DuPage, Cook, and Will (IL) and Lake and Newton (NW IN). Aug. 11: derecho; 70 to locally 100+ mph from NE Illinois into NW Indiana; estimated peaks 100-110 mph in parts of northern Lake and Porter (IN); 99 mph at Gary/Chicago airport. NWS: 8 tornadoes in its area, widespread tree and line damage, outages over two weeks in parts of NW Indiana, one Gary fatality from straight-line winds. Aug. 11 damage was likely worsened by injury from July 27. Aug. 18-19, seven days later, a different weather system. 43,449 samples at ~1 Hz, Aug. 18 21:08:54 CDT to Aug. 19 09:13:08 CDT (12.07 h). Evening pulses to 0.667 uT at 21:15:23 CDT matched convection over southern Lake Michigan; the median floor then returned to ~0.15 uT while multi-axis pulses continued. Session max 1.171 uT at 07:51:51 CDT, ~15 s above 0.85 uT. The 08:55-09:12 window peaked at 0.418 uT. 14:00Z radar for ZIP 60640 shows the metro clear; remaining rain was hundreds of km away. Grid and appliance noise remain confounds and more often raise a floor than a 15-second three-axis burst. Exotic ELF induction may be present; no transmitter, operator, or purpose is identified, and it is not treated as fact. 1.171 uT is 0.59% of the ICNIRP 2010 public reference of 200 uT rms (25-400 Hz). July peaks are still ~1%. No exceedance is claimed (Health Physics 99(6):818-836, 2010). IARC 2B concerns chronic 50/60 Hz averages near 0.3-0.4 uT. The 12-hour mean was 0.187 uT; some pulses reach that band. This is not a dose survey or a health assessment. A 1-second fixed magnetometer plus radar can show a baseline, a climb, a pulse, and a radar-quiet continuation. It cannot name a source. Still needed: a lightning overlay on the Aug. 18-19 pulses (especially 03:44, 07:51:51, and 08:55-09:12 CDT); any other magnetometer files for July 27 and Aug. 11; orientation, passband, and at least 2.5 readings/s; more than one station; paired air quality if the smog coincidence is studied. RF monitoring will not see a 30-2000 Hz magnetic pulse. The comment asks whether any federal system archives ELF magnetic fields, and whether a small archive should sit with weather radar. Nothing here shows these fields changed the weather. ELF at one station rose by roughly tenfold above a documented baseline in the weeks before two rare ~100 mph wind events, and a week later the session maximum occurred on clear local radar. Artificial induction aimed at that destruction is a hypothesis to test, not a finding. Test it with a lightning overlay, other magnetometers from July 27 and Aug. 11, and a physical account of whether a field of this size and band can couple to a storm. Publish an exclusion if one is earned. Asks: (1) Accept ELF logs below the ICNIRP level under Q14 and Q18. (2) Ask NOAA and NWS Chicago to reanalyze July 27 and Aug. 11 with any ELF records, and match the Aug. 18-19 file to a lightning network. (3) Ask CDC and state health offices to keep the injury, death, and outage burden in view, without assuming a field mechanism. (4) State what measurement would confirm an artificial ELF source and what would retire it. (5) Keep the limits: smog is only co-occurrence; the meter did not act on the weather; neither file is the derecho.
