Mine seneste observasjoner slik de er rapportert til VSNET. Merk
spesielt (1) det store lysfallet til R Coronae Boralis (og med
henvisning til et NAS.VSS-kart); (2) observasjoner av den nye novaen
i Reven (Nova Vulpeculae 2007) og link til kart; (3) SS Cygni er
endelig i oppbluss for første gang siden månedsskiftet april-mai.

Med vennlig hilsen
Bjørn H. Granslo
