Well here are at the 5th of June, only 2 weeks since the Penguin 2.0 and it would appear that Google has unleashed a major update on us. Now it would seem to be shaping up to be bigger than Penguin 2.0 so it is not likely to be a data refresh. This is starting to look like a full blown update.
Is this the promised softening of the Panda algorithm? Matt Cutts said there could possibly be some good news for sites that were hit by Panda but were on the cusp. Well if it is the softening of Panda it is appears to be having more of an impact than penguin 2.0 did.
Mozcast.com is showing 95 degrees and Stormy.
Serps.com is showing a volatility spike.
The SerpMetrics.com flux has moved slightly but isn’t showing the same dramatic blip the other two Serp trackers are. Traditionally SerpMetrics is the most conservative of the big search engine trackers. If they show a spike in the next day or two then we are pretty well guaranteed that Google has launched a dramatic update to the index.
There is a WebmasterWorld thread dedicated to SERP changes in June which has had quitre a bit of chatter in the last few hours.
Update 6th of June 2013 :
Dr Pete from Mozcast.com and Moz.com tweeted that he had to revise the temperature down to about 81 degrees for that spike we saw on the 4th of June. His explains his reasoning in the following tweet.
Due to massive data center differences, I’m adjusting yesterday’s @mozcast temp down to 81 deg. F.

By the 5th everything seemed to return to normal. The Serps.com volatility index followed Mozcast’s trend graph pretty closely and it was all over by the 5th also. the fact that these two serp trackers follow each other pretty closely is very interesting in itself. Seprmetrics.com flux was slower to come on and didn’t spike as hard as the other two but seems to be still going as of the 5th. Another thing I have realised is that the Serpmetrics data does seem to lag somewhat from the other two Google tracking websites.
