V2362 CYGNI
This nova continues to exhibit a very unusual light curve with a strong 
re-brightening well after maximum. The light curve is displayed at:

http://www.theastronomer.org/vars/2006/V2362CygLC_V5.gif

Since the latest WWW update, further magnitude estimates suggest it has 
now reached magnitude 10.0v on Nov 28 (Gary Poyner).

The editor has consulted with Professors Mike Bode and Nye Evans 
regarding this unusual light curve and it is agreed that it is unlikely 
to be a dust clearance episode and probably also not a light echo 
effect.

They have obtained time on Spitzer to study this object and ask that we 
keep them fully informed of the brightness trend especially if a fade 
sets in. Please send observations to the editor daily as well as the 
usual report to Gary Poyner at month end.

ERUPTIVE YOUNG STELLAR OBJECT IN LDN 1415
J. Kastner and M. Richmond, Rochester Institute of Technology, et. al., 
report on CBET 760 that an exposure on 2006 Nov 18 with the Chandra 
X-ray Observatory's Advanced CCD Imaging Spectrometer imaging array of a 
field centred at: RA 04h 41m 35.8s DEC +54 19' 20" (2000), recorded a 
low-luminosity, eruptive, young stellar object reported earlier by 
Stecklum (CBET 690).

No x-ray source is detected within several arcminutes of this
position.  The upper limit on the Chandra/ACIS-I count
rate within a 10"-radius circular aperture centred on the Stecklum
position is < 0.67 count/ks corresponding to an upper limit on observed 
x-ray fluxes of < 3.9 x 10**(-15) and < 5.0 x 10**(-15) erg cm**(-2) 
s**(-1) for assumed plasma temperatures of 10 and 30 MK, respectively. 
The emergent source x-ray luminosity is hence constrained to be less 
than about 2 x 10**(28) erg s**(-1), assuming that the distance to the 
L1415 cloud is 170 pc.  The intrinsic source x-ray luminosity is not 
well constrained, however, given that the star is likely encircled by a 
circumstellar disk that is viewed almost edge-on (Stecklum et al. 2006,
http://xxx.lanl.gov/abs/astro-ph/?0611314).
