W. Russell et. al., The Aerospace Corporation and others report on IAUC 8956 0.8- to 5.5-micron spectroscopy of V2670 Oph (= Nova Oph 2008 No. 1, TA E-Circulars 2451, 2452 and 2454) on 2008 June 14 UT using SpeX at the Infrared Telescope Facility. It displays a generally low-excitation spectrum with lines of neutral carbon, nitrogen, oxygen, and sodium, and singly ionised iron and calcium. V2670 Oph is probably an "Fe II"-type nova. There is no evidence at present for dust formation. VY AQUARII Further to the note on TA E-Circular 2458 reporting an outburst of this eruptive star, Eddy Muyllaert of Belgium reports that it has apparently brightened again after an initial fade. On July 21.133 it was 14.66 (CCD unfiltered) but rose to 12.8 on July 21.961UT (visual). A further note has appeared on AAVSO Special Notice #114: Several observers have reported that the dwarf nova VY Aqr has re-brightened since fading from its initial superoutburst. Although VY Aqr has been classified as a WZ Sge-type dwarf nova, previous superoutburst re-brightenings have not been well-observed. Continued monitoring of VY Aqr for the next several weeks is strongly encouraged. Both visual and CCD time-series observations are needed, the former to track the overall light curve, and the latter to study superhumps and short-term variability. Both positive and fainter-than estimates are valuable, so please continue to monitor VY Aqr if and when it becomes faint again -- it may undergo further rebrightenings during this outburst.
