Google tweeted late last night that it has begun rolling out a new data refresh of the Panda update. The refresh affects about 1% of search results in a noticeable way, according to the company.

The last Panda update data refresh we saw was in late June, and that was the second one during that month. It was a rarity for Google to roll out two refreshes to this update in a single month.
Google did, however, announce last week, that it was launching Panda for Japanese and Korean, affecting about 5% of queries (with no other languages affected at all).

Remember, the latest announcement was just a data refresh. For more on what that means (vs. an update), see what Google’s Matt Cutts had to say about it here.
