The iButton inside the brass chamber was suspended from a tree branch just below the surface of the Peeper swamp for 48 hours starting at 8pm. The following day, it was very warm with the air temperature rising above 90 degrees. Both the night before and night after were much cooler as was the second day. Temperature sample rate was 5 min/sample (horizontal scale is 5 minutes/tick mark). Information about iButtons is available by clicking on the title of this post which links to the Maxim-IC site.
