I just read this in the EURCHF forum, no official word yet but it looks pretty promising that this is an intervention...
UBS:
EURCHF: looming interventions? (February 4, 2010, 5:48 PM)
EURCHF dropped to its lowest level since the intervention took place last Friday. The SNB committed to preventing any excessive appreciation of the CHF against the EUR. We expect the SNB to intervene again should the CHF continue to appreciate against the EUR in the coming days.
