Dear colleagues, Lasse Teist Jensen has just informed us of a new outburst of V446 Her, one of the VSNET campaign targets (see vsnet-campaign-news 16, http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/Mail/vsnet-campaign-news/msg00016.html). The current magnitude is V~15.5. It is quite important to reveal the whole outburst shape and the recurrence pattern in V446 Her in order to understand the physics of the accretion disk in post novae. We encourage observers to joing this interesting campaign! More information about this campaign is available in vsnet-campaign 446 and vsnet-campaign 325, http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/Mail/vsnet-campaign/msg00446.html http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/Mail/vsnet-campaign/msg00325.html . Best regards, Matthias Schreiber, Boris Gaensicke, Daisaku Nogami
