The AGILE Gamma Ray Imaging Detector (GRID) detected Mrk 421 in the period between 2008-06-09 17:02 UT and 2008-06-15 02:17 UT during a Target of Opportunity (ToO) re-pointing towards W Comae. A preliminary maximum likelihood analysis shows a detection at a significance level of about 4 sigma, at energies above 100 MeV. During the AGILE ToO, the Super- AGILE hard X-ray monitor detected Mrk 421 in a relatively high-state, with a source flux of about 40 mCrab, in the energy range 18-60 keV (see Costa et al., ATEL #1574).
