Dear Dan and Brian,
Please find below the text of an IAUC which we are submitting on Nova
Aquilae 1993.
Cheers, Mark Wagner
NOVA AQUILAE 1993
S.J. Austin and S.G. Starrfield (Arizona State University) and R.M.
Wagner (Ohio State University) report: Optical spectra of Nova Aquilae
1993 were obtained with the Perkins 1.,8-m telescope and CCD
spectrograph on May 17.35 UT. The spectra (range: 330-870 nm,
resolution: 1.2 nm) exhibit strong permitted emission lines due to the
Balmer series of hydrogen; Fe II (multiplets 37, 38, 42, 48, 49, 73,
and 74); O I 777.4 and 844.6 nm; Ca II (H, K, and the infrared
triplet); Na D; and Mg II 823.2 nm. Many of these lines show P Cygni
absorption profiles. The H-alpha emission line profile is very
asymmetric to the blue side of line center. The spectra confirm the
identification as a "Fe II class" nova in the early post-maximum phase
of its development.
