Nova confirmed ! TCP J18102829-2729590

 Visit page
 A confirmation spectrum of TCP J18102829-2729590, a galactic nova in Sagittarius. The target, setting rapidly in the west, was imaged using the Alpy 600 under challenging conditions, providing confirmation as a classical nova in the optically thick stage. The resulting ATel (kindly prepared by Steve Shore, University of Pisa) can be found here. Additional spectra at both high and low resolution have been acquired and made available via the ARAS spectral database.
