摘要
This paper presents the first AGN detections with the USA X-ray detector on board of ARGOS. We started observing the BL Lac object Mkn421 at the end of January 2000, when it was also observed by the CAT Cerenkov telescope (see Pierre Espigat, these proceedings), and optical telescopes (but the latter are not presented here). Mkn421 was at the beginning of a long period of high activity that lasted for many weeks. Some observations on Mkn421 were also carried out in this period by XTE (see Rita Sambruna, these proceedings).
