NOVA SAGITTARII 2008
Hiroshi Yamaoka, Kyushu University, reports that K. Haseda, Japan finds 
nothing brighter than mag 11.5 at the position of N Sgr 2008 (cf TA 
E-Circular 2440) on his patrol images taken around Apr. 15.743UT with a 
Canon EOS-5D digital camera (+ 120-mm-f.l. lens). Yamaoka adds that M. 
Fujii (Kurashiki, Okayama, Japan) took a low-resolution spectrum with 
his 0.28-m reflector on Apr. 19.82 UT, revealing Balmer lines and 
several broad absorption lines; the H_alpha line shows a prominent P-Cyg 
profile, which suggests that it is a genuine classical nova around or 
soon after maximum.

2005 NB_7
M. K. Shepard, Bloomsburg University of Pennsylvania et. al., report on 
IAUC 8936 :  "Arecibo delay-Doppler images obtained on Apr. 11-12 show 
that the Apollo-type object 2005 NB_7 is a binary system.  Preliminary 
estimates of average diameters, based on range estimates at 7.5-m 
resolution, are 0.5 and 0.2 km (+/- 0.1) km. The rotation period of the 
primary has not been determined, but based on the estimated diameter and 
observed bandwidth is >/= 2.5 h.  The semi-major axis of the relative 
orbit is >/= 0.6 km; the system orbital period is not known."
