WEBT: MKN 421 news Date: Wed, 24 Jan 2001 10:37:59 +0100 From: Massimo Villata <villata@to.astro.it> WEBT News 6 - January 24, 2001 Mkn 421 high-energy outburst Mkn 421 is showing strong X-ray and TeV activity (see message below). Leo Takalo is observing the source at the NOT. Other optical observations are encouraged. Please, let me know if you are observing and keep me informed on possible optical data (finding chart at http://vsnet.lsw.uni-heidelberg.de/projects/extragalactic/charts/1101+384.html). This is not an official WEBT campaign at the moment, but interesting optical data could trigger one. Massimo Villata (vsnet-alert message by Ron Remillard omitted)
