Nowe (słabe) komety C/2004 Q1 TUCKER & C/2004 Q2 Machholz
#1
Choć prawdopodobnie niewielu z nas będzie dane ją obserwować to warto śledzić jej zachowanie bo komety lubią płatać figle

IAU Circular 8393 (August 25, 2004) reports the discovery of a comet by Roy A. Tucker on CCD images taken with a 35cm reflector on August 23 UT. The comet is reported as m1~14.6, Dia=50", with a 70" tail. A preliminary ephemeris on the same circular indicated a perihelion date of Dec. 10, 2004 with q=2,0 AU. The comet is expected to brighten over the next few weeks and be well-placed in the midnight sky. The comet should become a faint telescopic object for visual observers (m1~13.0).

A tu jej pierwsze oceny jasności :

Juan José González Suárez (Alto del Castro - Aralla, alt. 1720 m, Leon, North Spain)
C/2004 Q1 (Tucker):
2004 Aug. 26.14 UT: m1=12.9, Dia.=1.5', DC=3, 20 cm SCT (100x)

P. Clay Sherrod (ASO Petit Jean Mountain)
C/2004 Q1 (Tucker)
2004 Aug. 26.26 UT: m1=12.4 (*), Dia.=25", DC = 6/9, 0.41m SCT/ccd 10x50B P. Clay Sherrod, (A very nice comet, with a uniform coma, about 0.5', tail fans in PA 228 and there is a fairly strong central conds).

Obecnie jest oddalona od Ziemi o (delta= 1.7757 AU) a od Słońca o (r= 2.3717 AU)
Peryhelium przejdzie 10 XII 2004 r. (q= 2.00387 AU) a najbliżej Ziemi znajdzie się wcześniej bo 24 X 2004 r. 2:53:28 UT (delta= 1.12361 AU)
Największą jasność osiągnie ok. 31 X 2004 r. 14:23:23 UT

To są dane wyliczone, które w rzeczywistości mogą się nieco zmienić, zwłaszcza data maksymalnej jasności. O dziwo powyższe amatorskie obserwacje wskazują na większą jasność komety o 2 mag. niż podaje MPEC.

To na razie pierwsze obserwacje. Zobaczymy jak będzie po kilku następnych...

Ta kometa jest jednak słaba i DARK umieścił o niej info tylko dlatego, że kometa ta została odkryta przez "amatora" :Smile i takież to oznaczenie otrzymała. Ileż można słuchać o NEAT-ach i LINEAR-ach Wink

Kolejne odkrycie komety przez amatora-łowcę komet Dona Machholza.
IAU Circular 8394 (August 27, 2004) reports the visual discovery of a comet by our friend Don Machholz (Colfax, CA) - his 10th discovery - using a 25cm reflector. The comet was reported to be m1=11.2 , coma diameter = 2' with a moderate degree of condensation. It is moving eastward (and slightly to the south) less than a degree per day. A position at Aug. 28.82 UT (based on a precise position by Rob McNaught and Gordon Garradd, Siding Springs, Australia reported on the same circular) for the comet is RA 4h 16m 41s, DEC -22 deg 23' 37s. No orbit is currently available.
Tym razem kometa trochę jaśniejsza bo ok. 11 mag. Narazie niewiele mi wiadomo o prognozowanej janości jak i jej orbicie więc trzeba poczekać na dalsze informacje na ten temat.
