V5668 Sagittarii = N Sgr 2015 No. 2 = Pnv J18365700-2855420

As first announced on CBET 4080, J. Seach (Chatsworth Island, NSW, Australia) reported his discovery of an apparent nova (mag 6.0) in three images (limiting mag 11.0) taken on Mar. 15.634 UT with a digital SLR camera (+ 50-mm-f.l. f/1.0 lens); he gave the position of the new object as R.A. = 18h36m57s.0, Decl. = -28o55'42" (equinox J2000.0); he added that six follow-up images taken with an H_alpha filter on Mar. 15.726 showed the star as a bright H-alpha source. E. Guido and N. Howes reported position end figures 56s.85, 40".0 for the variable from an image taken on Mar. 16.5 with a 0.61-m astrograph. J. Powles, Canberra, ACT, Australia, reported that low-resolution spectroscopy obtained on Mar. 16.628 with a 25.4-cm reflector spectrogram show the H-beta line and emerging Fe II emission lines, suggesting this to be a classical nova of the "Fe II" type. The nova peaked near visual mag 5 in mid-March. Further details are given on CBET 4080. The variable was designated PNV J18365700-2855420 when it was posted at the Central Bureau's TOCP webpage. E. Kazarovets and N. Samus note that the permanent GCVS designation V5668 Sgr has been assigned to this variable.
