Hi all,

two comets tonight. When I went into 'Matrix Reloaded' it was pouring
down, when I emerged it was crystal clear and still...

P/Wild 4 (116P) 2003 May 23.52 UT: m1 = 11.8, Dia.= 1', DC = 5, 41cm
f4.5 Reflect (88x)…John Drummond, (Gisborne, New Zealand) [116P looks
like a bright smudge with a fairly knot-like condensed nucleas.
Comet's alt is 64* in the NW. Stellar LM =15.6, diffuse LM = 14.4
(scope).

53P (P/Van Biesbroeck) 2003 May 23.55 UT: m1 = 14.0, Dia.= 0'.5, DC =
6, 41cm f4.5 Reflect (166x)…John Drummond, (Gisborne, New Zealand)
[53P appears to have a condensed nucleas with a faint ghostly haze
around it. Comet's alt is 57* in the NW. Stellar LM =15.5, diffuse LM
= 14.3, (scope).]

Cheers

John D

f4.5 Reflect (166x)…John Drummond, (Gisborne, New Zealand) [116P
appears as a brightish smudge with a fairly condensed nucleas. Comet's
alt is 73* in the N. Stellar LM =15.6, diffuse LM = 14.4 (scope)].

53P (P/Van Biesbroeck) 2003 May 09.53 UT: m1 = 14.2, Dia.= 20", DC =
7, 41cm f4.5 Reflect (166x)…John Drummond, (Gisborne, New Zealand)
[53P can be glimpsed as a small faint patch with a condensed nucleas.
Comet's alt is 61* in the N. Stellar LM =15.6, diffuse LM = 14.4,
(scope)].

In spite of incoming high cirrus, we were able to get a few faint comets
early this morning; they are posted as always at:
http://www.arksky.org/
under the Comet Patrol tables.  Note that no trace of C/2003 H1 was visible
in three images to mag. 18.2 stellar; seems it may have faded rapidly;
nothing even close to predicted.

Hi all,

Had a fine, still night here in NZ...

C/2001 RX14 (LINEAR) 2003 April 30.32 UT: m1 = 12.0, Dia.= 40", DC
= 5,  41cm f4.5 Reflect (166x)…John Drummond, (Gisborne, New
Zealand)  [My first view of RX14 (northern object until now). Not
overly bright, fairly condensed coma, 'average' size. Comet's alt is
32* in the N. Stellar LM =15.5, diffuse LM = 14.3 (scope).]

P/Wild 4 (116P) 2003 April 30.34 UT: m1 = 11.5, Dia.= 50", DC = 6,
41cm f4.5 Reflect (166x)…John Drummond, (Gisborne, New Zealand) [116P
appears as a fairly bright smudge with a condensed nucleas. Comet's
alt is 25* in the E. Stellar LM =15.5, diffuse LM = 14.3 (scope).]

Clay Sherrod, (ASO - Petit Jean Mountain,  H41)...[Comet is quite small, yet
easily identifiable as nebulous; rapid motion in astrometric imaging]

SCT/ccd.......P. Clay Sherrod, (ASO - Petit Jean Mountain,  H41)...[Very
short and broad extension now detected via ccd in PA 174 degree, fans until
disappears; some condensation and coma does not appear symmetrical]

skies and tail is difficult to define, but primary portion is centered at
170 deg PA, traced for about 1.8'length; coma is very large and uniformly
bright across diameter; (*m2=14.7 ccd)]
