Was playing around with some GIS today and put together this plot of the most incredible #lightning display of 2022 (and probably ever).

1-minute of GLD360 data every 10 minutes from 0420 UTC to 0540 UTC January 15 during the #HungaVolcano eruption.

9 panel image showing lightning data from the Hunga Volcano eruption on January 15. Each panel shows 1 minute of GLD360 data every 10 minutes between 0420 and 0540 UTC on January 15. The lightning rapidly increases in amount and shows distinctive rings propagating away from the volcano.
