Sziasztok!
Azt hiszem, az Eridanusban meg nem volt nova - legalabbis en nem
emlekszem ilyesmire. Az Itagaki altal talalt csillag lehet, hogy egy
tobb katalogusban is lathato 15 magnis csillag kitorese. Yamaoka szerint
a het magnitudos kifenyesedes kicsit nagy torpenovanak, viszont
klasszikus gyors novanak kicsi. Az ASAS-3 szerint a csillag az elmult
napokban 7,34 es 8,12 magni kozott halvanyodott.

POSSIBLE NOVA IN ERIDANUS
Hitoshi Yamaoka, Kyushu University, reports the discovery by K. Itagaki
(Yamagata, Japan) of a possible nova (mag 8.1) caught on Nov. 25.536 UT with
his 0.21-m patrol system. A confirming image taken by Itagaki on Nov. 25.545
with a 0.60-m reflector shows the object at R.A. = 4h47m54s.21, Decl. =
-10d10´43".1 (equinox 2000.0). Itagaki notes that there is a faint (mag about
15) object near this position on his archival patrol images. Yamaoka suggests
that it might be the brightening of a 15th-mag blue star that is contained in
many catalogues (USNO-B1.0 position end figures 54s.19, 42".9), noting that
the amplitude of seven magnitudes is rather large for a dwarf nova, but
somewhat small for a rapid classical nova. Yamaoka adds that the ASAS-3
system (Pojmanski 2002, Acta. Astron. 52, 397) also detected this object at
the following V magnitudes: Nov. 10.236 UT, [14.0:; 19.241, 7.34; 22.179,
7.98; 24.269, 8.12.
