Re: Cold anomaly in NE Portugal

Unless you are using an inverted palette, black on a IR image translates into hot, not cold. It looks to me as a small hot spot, probably a fire as suggested by Terence, but it is odd that it shows up best in Ch4 and much less so in Ch9.

Evening all,

Any one else see the _very_ cold (black) area in NE Portugal in the last
few IR images? Very obvious in Channel 4 from about 18:30 to 19:15?

Also on several other wave-lengths but not so obvious.

Any ideas as to what/why?
