. Images of the position of GRB080319B before the burst (left) and at the moment of maximal optical brightness (right). The transient position is marked with an arrow. Peak optical brightness made the burst visible by a naked human eye (5.3 stellar magnitude). To view high temporal resolution video of the transient seen by TORTORA camera, click here (avi).

Classical nova V2362 Cyg (N Cyg 2006, 21:11:32.34, +44:48:03.9, 2000 [position in ATel 928 is incorrect!] ) undergoes gradual increase of its brightness since middle of August, 2006 from the level of V = 11.9. ... Full width of Halpha line is 5900 km/s, and that one of Hbeta is 5300 km/s. We identified the strongest emission features as CIII+NIII blend centered on 4652A, [OIII]+NII blend on 5010A, NII+[NII] blend on 5708A, NaI+OI blend on 5920A. Absence of HeI lines at 6678 and 7065A is surprising. ...
