Indeed. 18/8 was two days after Nova Del's maximum. The emission lines present on 14/8 had all but disappeared, and had yet to reappear. The best spectral comparison date with Nova Cen would be 7 or 8 Dec.
We are currently 23 days after maximum for nova cen. It has fallen from 3.5 to 4.1 in that time. The equivalent for nova del was a fall from 4.2 to 7.3 23 days after maximum.
Del was quite a fast nova. But Cen is not only brighter; it's much slower.
