Akihiko Tago (多胡 昭彦 Tago Akihiko) is a Japaneseastronomer. Wikipedia does not yet have an article with this exact name. ...
He co-discovered several comets, including C/1968 H1 (Tago-Honda-Yamamoto), C/1969 T1 (Tago-Sato-Kosaka), C/1987 B1 (Nishikawa-Takamizawa-Tago). Comet Hale-Bopp, showing a white dust tail and blue gas tail (February 1997) Comet (disambiguation). ...
He also discovered several novas, including V1493 Aql (Nova Aquilae 1999) and V2275 Cyg (Nova Cygni 2001 no. 2). A nova is a cataclysmic nuclear explosion caused by the accretion of hydrogen onto the surface of a white dwarf star. ...
The combined V and I measurements suggest that the variable was slightly redder at max light than before and after, not by a significant amount (given the large uncertainties in the V-band magnitudes).
S. Nakano, Sumoto, Japan, reports the discovery by AkihikoTago (Ayabe, Tsuyama, Okayama-ken, Japan) of a brightening star on 30-s CCD frames taken with a 70-mm f/3.2 lens and a Canon EOS 20Da digital camera (limiting magnitude 12), with the following magnitudes available: Oct. 25.538 UT, 10.7; 27.409, 10.5; 30.411, 8.8; 31.469, 7.5.
Tago adds that a star of mag 11.8 (which did not vary on past images) is located very close to the new variable's position, for which he identifies GSC 3656.1328 with R.A.= 0h09m21s.81, Decl.= +54o39'43".8, equinox 2000.0);
The nova Aquilae 1999 (V1493) discovery has been reported by AkihikoTago, Tsuyama, on T-max-400 film taken on July 13.6 UT with a 55-mm f/3 lens.
On a film taken on July 14.5, Tago derived mag about 8.9 from the star.
K.Ayani and T.Kawabata, Bisei Astronomical Observatory (BAO), Okayama, report: "we obtained a low resolution spectrum (range 470-680 nm) of Tago's suspected nova on July 14.6 UT with the BAO 1.01-m telescope.
