[150.03] Following the Photometric and Spectroscopic Outburst of the ONeMg Novae V1187 Sco: The First Three Months

We have an ongoing program following the temporal evolution of classical novae using the SMARTS consortium suite of telescopes located at CTIO. These observations include UBVRI-JHK light curves using ANDICAM on the 1.3m, supplemented with optical photometric calibrations using the 1.0m. Spectroscopy in the optical at low to moderate dispersion is obtained with the 1.5m. Generally these data are augmented by observations made on other facilities, particularly the 3.5m telescope at Apache Point Observatory. Here we present work in progress covering the first three months temporal evolution of the classical ONeMg nova outburst of V1187 Sco.

V1187 Sco was discovered by A. Takao on 2004 August 3.583 UT near maximum brightness (IAUC 8380). Rate of decline from maximum indicates V1187 Sco to be a very fast nova with t₂ ~ 7 days, and t₃ ~ 16 days, and by mid-October had faded by ~ 5 mag at V. Emission lines are broad indicating velocities of ~ 3500 km/s, which are maintained throughout the first three months. We will present the photometric and spectral development of V1187 Sco based on SMARTS data.

This research has been supported in part by grants from NASA and NSF, with observing time enabled by the SMARTS consortium.
