[BAA Comets] 21p

[Peter Carson]

Hi Nick and Denis,
Not wanting to miss out I also imaged 21P earlier this morning, see attached 
image. Unfortunately it was a little murky and the comet was amongst a 
crowded star field so its tail is not visible.
I measured the comet as being +1.6'RA and +0.2'Dec different to the position 
calculated by using the MPC orbital elements.

Denis,

Nice image. Yes 21P is now available in the morning sky and it is
showing a faint tail in PA 250 or so. The MPC elements have still not
been updated and the comet is around 2 arcmin east of its predicted
position.

Let's hope this comet will put on a nice display later in the year.

Nick.
