IAU Circular No. 8574-5-6
NOVA SCORPII 2005
G. Pojmanski, Warsaw University Astronomical Observatory,reports the ASAS discovery (cf. IAUC 8402, 8495) of a possible novaon CCD images obtained with a 180-mm-focal-length (65-mm-aperture)telephoto lens, giving the new object's position as R.A. =17h44m22s, Decl. = -34o16'.5 (equinox 2000.0 presumed), which isnoted as being in an area crowded with nearby stars; V magnitudesfor the new object: July 23.287 UT, [14; 25.284, 9.11; 26.296,8.98; 26.311, 8.98. S. Nakano, Sumoto, Japan, reports theindependent discovery of this new object at mag 8.7 by HideoNishimura (Kakegawa, Shizuoka-ken, Japan) on two 30-s Kodak T-Maxfilms taken on July 26.565 with a Pentax 6x7 camera (+ 200-mm f/4.0lens), with position end figures given as 22s, 15'59" (equinox2000.0); nothing was visible at this location on Nishimura's surveyfilms taken on July 20 (limiting mag 11). Nakano also forwards thefollowing precise position from four unfiltered 20-s CCD framestaken by N. Hashimoto and T. Urata, Bisei Spaceguard Center, aroundJuly 26.596 using the 0.50-m f/2.0 reflector: R.A. = 17h44m21s.59,Decl. = -34o16'35".7 (magnitude 8.6). Nothing is visible at thislocation on Digitized Sky Survey images (no limiting magnitudeprovided); the nearest USNO-A2.0 star (red mag 17.4) has positionend figures 21s.987, 35".85.

M. L. Sitko and R. Kimes, University of Cincinnati; D. K.Lynch, R. W. Russell, and D. L. Kim, The Aerospace Corporation; andD. Griep, Infrared Telescope Facility (IRTF), report 3-14-micronspectroscopy of this object on July 27.375 UT using the instrumentBASS on the IRTF. The spectrum shows a smooth, featurelesscontinuum consistent with a Rayleigh-Jeans tail of a Planckfunction. The magnitude was approximately 4.8 in the bands L, M,and N. Visual magnitude estimates: July 26.735 UT, 8.9 (T. Cooper,Bredell, Kempton Park, S. Africa); 26.881, 8.9 (J. G. de S. Aguiar,Campinas, Brazil); 27.228, 9.0 (M. Linnolt, Woodside, CA).
V1188 SCORPII = NOVA SCORPII 2005
N. N. Samus, Institute of Astronomy, Russian Academy ofSciences, informs us that the designation V1188 Sco has been givento this nova (cf. IAUC 8574, 8575). H. Naito and N. Tokimasa, Nishi-Harima AstronomicalObservatory (NHAO); and H. Yamaoka, Kyushu University, report thata low-resolution spectrum (range 300-850 nm; resolution 150) ofV1188 Sco, obtained on July 27.6 UT with NHAO 0.60-m telescope (+NILS), shows a broad H_alpha feature (FWHM = 1730 km/s) with P-Cygprofile, suggesting that V1188 Sco is indeed a classical nova.Yamaoka adds that M. Fujii, Ibara, Japan, obtained a spectrum onJuly 27.53, which shows a clear H_alpha line in emission. F. M. Walter, State University of New York at Stony Brook; H.E. Bond, Space Telescope Science Institute; and A. Pasten, SMARTSand Cerro Tololo Interamerican Observatory (CTIO), confirm thatV1188 Sco is a classical nova near or before peak. A 0.31-nm-resolution spectrum (range 570-690 nm), taken on July 28.16 UTusing the SMARTS/CTIO 1.5-m RC spectrograph, shows broad H_alpha(FWZI = 4000 km/s, EW= -3.5 nm) and Fe II (74) lines in emissionatop a photospheric continuum with absorption lines. He I 587.6-nmappears in absorption; the Na D line (EW = 0.5 nm) shows threeabsorption components. The peak of the H_alpha emission isblueshifted by about 250 km/s; the P-Cyg absorption is blueshiftedby about 900 km/s. There may also be an absorption feature at +350km/s.
