Announcement of the campaign (2009/12/08)
The Fermi/LAT team is organizing a multi-wavelength campaign on the blazar Markarian 421, starting on December 8th 2009 and finishing on December 1st 2010.

For this campaign, the policy on data sharing will be: if you observe and send data that can be used, you are a co-author of a resulting multiwavelength publication unless you just want an acknowledgment. Anyone who contributes data keeps the right to publish those data separately. Yet those separate publications should be done in a coordinated way, so that we try to have the (potential) single instrument publications close in time to the multiwavelength publication.
Observation schedule
The instruments participating in the campaign, together with the (approximate) observation schedule can be found here (the schedule is often updated with new future observations as well as with the obs times from past observations).
Activity of the source during the campaign
Many of the instruments will be providing flux estimates (best efforts) from the observations performed during the campaign.
