1815-553 The spectral range of 5000-10000A is probably too red for this
object, as it seems to be very blue. It appears significantly brighter
on the IIIa-J plate of Jauncey et al. (1989). Our (red) spectrum is
featureless. This object, based on its colors, is probably a quasar.
1815-553: Optically variable. This object was roughly two magnitudes
brighter when observed by Jauncey et al. (1989).
1815-553: The brightness of the optical counterpart of 1815-553, derived
from our CCD image, is only m_R_ = 21.7 mag, nearly 3 mag fainter than the
value given by White et al. (1991), which indicates a significant, previously
unknown optical variability of this quasar.
The identification and magnitude were taken from White et al. (1991).
