Nova V459 Vulpeculae: Discovered independently by H. Kaneda (25 Dec 07) and A. Tago (26 Dec 07). GVO observations made from 27 Dec 07 into early Jan 08. The star appears light orange in the telescope; the measured color indices show a spectral shift in the energy output: B-V decreased by 2X while V-R and V-I increased by ~10%. V459 Vul faded by more than 1 magnitude in 10 days, suggesting a Type NA nova. The proximity to the horizon and attendant time constraints preclude our obtaining spectra, but we have been able to make single-channel multi-band photometric measurements in BVRI and Wing ABC bands.
The table lists the BVRI results, transformed to the standard system and corrected for atmospheric extinction.
