This is a summary of the August 6, 2018 Holy Fire in the Holy Jim Trabuco Canyon area data, as seen from the HPWREN Santiago Peak South pointing camera. The camera with its 3072x2048 pixel images is fixed, and cannot be optically panned, tilted, or zoomed. The timestamps in the upper left were inserted by the processing server at UCSD when an image was acquired; they are synchonized via NTP, and high reliability is very likely.
The 480 typically once-per-minute images that are represented in this 09:01-17:59 set were acquired from an HPWREN archive data server via a script:
mkdir sp-s-mobo-c for i in Q4 Q5 Q6 do for j in sp-s-mobo-c do scp -p "c1.hpwren.ucsd.edu:/Data/archive/$j/large/20180806/$i/*" $j done done
and encoded into a downloadable full 3072x2048 pixel time-lapse animation by using ffmpeg:
ffmpeg -framerate 7 -pattern_type glob -i "sp-s-mobo-c/*.jpg" -i /home/hwb/overlay-3072-2048.png -filter_complex '[0:v][1:v]overlay[out]' -map '[out]' -vcodec libx264 -pix_fmt yuv420p -crf 21 -threads 0 -metadata title=HPWREN 20180806-Holy-sp-s-mobo-c.mp4
The individual images were retained in a folder that displays them individually via clickable thumbnails. Of particular interest could be

as they seem to show the origin location and time of the fire. A 13:06 image was not available, most likely due to packet/image losses with the Santiago Peak site.
