Dear colleagues, V446 Her is a current campaign object (for more detail, see vsnet-campaign 325). We would ask observers to make a close monitor of this star to reveal the whole shape of this outburst. Note that time resolved photometry is not necessary, but occasional imaging, say, each 2-3 hours, is enough. We hope many observers to join this campaign! Thanks, Elena, for your timely notification of this outburst! Best regards, Daisaku Nogami on behalf of the V446 Her campaign team
