The RIPE NCC Routing Information System saw a very similar picture:
Flapping from  01:20:50Z - 01:38:22Z, consolidation 01:59:46Z - 02:28:20Z.

For details see:

is quite useful in answering questions like this,
i.e. "What happened to prefix x.y.z/a between times t and u?"
It is near real time with a lag of typically 5 minutes.
