[vsolj-alert 166] Rapid fading of Nova Oph 1998



Rapid fading of Nova Oph 1998

 へびつかい座新星の急激な減光が指摘されています。現在16等以下に減光して
 いる模様で、CCD等による追跡が望まれます。精測観測によって爆発前のUSNO
 星との同定についてもさらに情報が得られるかも知れません。

In the course of spectroscopic imaging at the Wise observatory on August 2nd,
Noph98 appeared to be fainter than about magnitude 16.

Reports from July 23rd.  estimate the magnitude at around 14.5. My
latest observation indicates that the nova is considerably fainter than the
comparison star 14.4 to its south and even a bit fainter than the ~15.5 mag
stars in the field.
