Еще одна комета вспышнула!
COMET 169P/NEAT
--------------------------------------------------------------------------------
M. Jaeger, Vienna, reports that his co-added CCD images of
this comet (cf. IAUC 8578, 8591) taken on Sept. 6.11 and 7.11 UT
with a 0.20-m Schmidt telescope, with the comet low in the morning
sky, show a coma of diameter 2'-2'.5 and (on Sept. 7.11) a faint
tail approximately 10' long. A. Hale, Cloudcroft, NM, reports that
his visual observations on Sept. 12.48 (0.2-m reflector) and 13.47
(0.41-m reflector) show the diffuse comet at total mag 11.5 with a
coma diameter of 1'.5 and some slight condensation. Hale had
previously observed the comet in early August, when it appeared as
an essentially stellar object of mag approximately 14.5-15.0.

"Alan Hale observed the comet visually at 11m5 and a diameter of 1'5, slightly
condensed."
"In my recent estimate, 169P/NEAT is clearly brighter :
2005 Sep. 14.19 UT: m1=10.3, Dia.=3', DC=2/, 20 cm SCT (100x), ( Alto del Castro
- Aralla, alt. 1720 m, Leon, North Spain ) [ Mountain location, very clear sky.
Zodiacal light. Altitude: 12 deg. ].
ICQ Format:
169 2005 09 14.19 S 10.3 TK 20.3T10 100 3 2/ ICQ XX GON05
