Alert Notice 634: Nightly monitoring requested for V1280 Sco = N Sco 2007

May 11, 2018 : Dr. Frederick Walter (Stony Brook University) has requested AAVSO assistance in monitoring V1280 Sco (Nova Sco 2007).

After it appeared as a nova in February 2007 (AAVSO Alert Notice 346), V1280 Sco reached visual magnitude ~3.8 (several observers), then faded to about 13.2, brightened to about 12.7, and underwent a dust dip in June 2007 to <15.6 V (P. Nelson). It recovered to about 10.3 by about a year later.
