  MAGIC, a stereoscopic cherenkov telescope array, sensitive to gamma-rays
between 50 GeV and several tens of TeV, is ideally suited to observe promising
Fermi LAT sources with a hard \gamma-ray spectrum. Here we discuss the
discovery of very high energy gamma-ray (VHE, E > 100 GeV) emission from the
Fermi LAT sources 1FGL J2001.1+4351 and B3-2247+381 with MAGIC. 1FGL
J2001.1+4351, recently identified as MG4 J200112+4352 (Bassani et al. 2010), is
most likely a high peaked BL Lacertae object. The red shift of this source is
still unknown, though the identification of the optical host galaxy suggests z
< 0.2. MAGIC observations indicate short term variability, since the source
showed a strong emission of 20% of the Crab Nebula flux above 90 GeV during the
16th of July 2010 and none of the other observation nights yielded a detection.
B3-2247+381 is classified as a BL Lac object at z = 0.1187 (Veron-Cetty & Veron
catalogue of known AGN). In July 2010 it showed increased optical activity in
the Tuorla blazar monitoring program, which subsequently activated target of
opportunity observations by MAGIC. Within 18 hours of observation time extended
over 13 days between September and October 2010, a strong signal was found
above an energy threshold of 150 GeV. The flux (4% of the Crab Nebula) is
consistent with being constant over the entire observation campaign. We compute
the light curves, model the spectral energy distributions of these new very
high energy gamma-ray emitters and discuss the physical properties of the VHE
gamma-ray emission region.
