The two BL Lac objects, 1ES 1215+303 and 1ES 1218+304, separated by 0.8degree, were observed with the MAGIC Cherenkov telescopes in 2010-2011. TheJanuary 2011 observations resulted in the first detection above 100 GeV of 1ES1215+303 (known also as ON-325) which has been flagged as a promising Very HighEnergy (VHE, E > 100 GeV) gamma-ray source candidate by the Fermi-LATCollaboration in October 2010. The January 2011 observations were triggered bythe high optical state of the source, as reported by the Tuorla blazarmonitoring program. A comparison with the 2010 data suggests that 1ES 1215+303was also flaring in VHE gamma-rays. In addition, the Swift Target ofOpportunity (ToO) observations in X-rays showed that the flux was almostdoubled with respect to previous observations (December 2009). Instead, 1ES1218+304 is a well known VHE gamma-ray emitter located in the same field ofview, which was then simultaneously observed with MAGIC. In this contributionwe present preliminary results of the MAGIC observations of these two VHEgamma-ray emitting AGNs.
