From the 40th AAS DPS meeting.

Spitzer has determined the IR brightness temperature of the following planets.

Gliese 436 b -> 461.5 +/- 43.3 K
HD 149026 b -> 2123.4 +/- 155.8 K
HAT-P-1 b -> 1305.5 +/- 139.1 K
TrES-2 b -> 1677.7 +/- 205.4 K
WASP-1 b -> 2201.5 +/- 253.9 K
WASP-2 b -> 1448.8 +/- 157.8 K
