Its interesting to note that this observation was made as the object peaked at a mid-infra-red absolute magnitude of about -24.2 in the 4.5 micron Spitzer/IRAC band. This band remains productive nonetheless, after the liquid He depletion of Spitzer, in late 2009.
The WISE telescope is referred to at the end of the article as the place to look for more of them:

"I would expect WISE to see 100 of these events in two years, now that we know what to look for"

The WISE group's bid for continued funding for an extended "warm mission" was recently scored low by a NASA review board, in part because of a lack of outside groups publishing on WISE Data. Such a mission would have allowed use of the 3.4 and 4.6 micrometre detectors after the last of cryo-coolant had been exhausted, with the goal of completing a second sky survey to detect additional objects and obtain parallax data on putative brown dwarf stars.

WISE has already completed one total sky coverage survey, in July of this year.

A very interesting read.
