Notes for object PKS 1815-553

4 note(s) found in NED.


1. 2000A&AS..143..181D
Re:PKS 1815-553
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.

2. 1999A&AS..139..297C
Re:PKS 1815-553
1815-553: Optically variable. This object was roughly two magnitudes
brighter when observed by Jauncey et al. (1989).

3. 1996A&AS..115...11S
Re:PKS 1815-553
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.

4. 1994A&AS..105..211S
Re:[KWP81] 1815-554
The identification and magnitude were taken from White et al. (1991).
