<DIV>Hi Wendy,</DIV>
<DIV>Well done for capturing this faint comet, perseverance pays off. I imaged
46P again this morning see my images here <A
title=http://www.astromania.co.uk/46P_20180817_0229_PCarson.jpg

It appears to be showing hints of a tiny tail. I had two previous failed
attempts from home on the 3rd and 5th Aug before I first captured it on the
11th. The comet was at an altitude of 19 degs on the 11th and 21 degs this
morning, rather low. Fortunately there are some patches of my southern horizon
where I can get down to about 12 degs altitude, although the sky’s rubbish down
there.</DIV>
<DIV>Like you my astrometry this morning was only RA 0.1’ different from the MPC
prediction. When I last measured 46P I had forgotten to update MPCorb which led
to the large differences.</DIV>
<DIV>Keep up the good work.</DIV>

<DIV>I was 0.1' out on RA and 0.0' on the Dec with all my measurements.</DIV>
<DIV> </DIV>
<DIV>This is the first time I've managed to get the comet too and I've been
trying since 11 May! Most of my data up until now has had the comet some
way off from the predicted position and neither myself nor an experienced
astronomer could be sure of it in any data I had between 11 May and 9 July and
that was using some big aperture scopes. I'm obviously pleased I nabbed it
now. What altitude was it when you imaged on 11th?</DIV>
<DIV> </DIV>

<DIV>Hi All,</DIV>
<DIV>Here’s my first image of comet 46P Wirtanen taken yesterday morning 2018
Aug 11th. <A title=http://www.astromania.co.uk/46P_201808110224_PCarson.jpg

<DIV>The comet appears to be some distance off the MPC predicted position (RA
+1.4’ DEC +0.7’), but I’m sure it is 46P I’ve measured.</DIV>
<DIV>To make me feel better has anyone else measured its position
recently?</DIV><SPAN class=HOEnZb><FONT color=#888888>
