Astrometry

 

Peter Birtwhistle, J95

 

Peter reports: October provided 13 usable nights for me, about the same as last year, but with only about half the number of hours spent observing it was a rather disappointing month.

 

A few interesting objects were observed, 2007 UN12 and 2007 US51 were both discovered by the Catalina Sky Survey soon after passing between Earth and Moon. 2007 UN12 passed less than 6 Earth diameters from us on Oct 17th and was discovered four days later, and 2007 US51 passed about half the distance of the Moon on Oct 30 and was discovered about a day later.

 

Another object put onto the NEO Confirmation page twice during the month (and on a number of occasions in the past too) was artificial satellite WMAP. Sitting at the L2 Sun-Earth Lagrangian point it appears as a very convincing NEO in close proximity to Earth and with plenty of orbital corrections being required to keep it in position it is impossible to predict accurately where it will be over a period of months. It will probably keep making appearances on the NECP as it gets 're-discovered' by the surveys every now and then!

9. ADDITIONAL COMMENTS

(Report submitted to Gilles Regheere and PLANOCCULT.)

 

This observation was difficult to analyse. The star was seen through thin

moving moonlit cloud (moon 84% snlt, distance 9). The real-time video

appeared to show a definite occultation. But the disappearance and re-

appearance looked to be gradual. Mag 9.5 star TYC 5804-1727-1, 4 arcmin

away, remained continuously visible although varying in brightness due to

the cloud. But very fine structure in the cloud meant that variations in

brightness of this and the target star (10.4m) were not synchronised. Analysis

with Limovie using the second star as a comparison was not very helpful

although it generally confirmed the central part of the occultation. The

video clip was digitised using a Matrox Meteor II card and the 'GRABSEQ'

utility of Sirko Molau's 'METREC' software. Every frame was examined

(pixel by pixel!) to obtain the times above. But it is impossible to tell

if the 'gradual' events at the beginning and end were due to 'graze'

phenomena or cloud.

 

All original data has been preserved.

A negative result as expected.

8 ADDITIONAL COMMENTS

 

Tried this one partly as a test for a Stellacam 3 I think mag. 15 is

about the limit with my equipment in SE England and you would not get

a very accurate timing. In the same FOV I could also see a couple of

faint galaxies IC1711 and UGC01076.

8 ADDITIONAL COMMENTS

Prediction obtained from Dave Gee's e-mail to Planoccult (http://

tinyurl.com/yp9jud). However this was also a test of a Stellacam3 (a

cooled Watec WAT-120N) I found that I had to use maximum gain and 64

frames integration with the 305mm reflector working at f2.1. His

suggestion of 32 frames did not reliably show the 14.8 mag. star. No

obvious occultation longer than 2-3 seconds.

 

------------------------------------------------------------------------------------------------

 

As I was not sure the target star would be high enough to see from

home I decided to travel east where also the weather was expected to

be better. This would put me near to the predicted centre line. I

left home in the rain and arrived in moonshine. Not too much problem

from the Moon but a few very thin clouds passing occasionally. When I

returned home it was much more cloudy so the weathermen got it right

for once. Judging by Andrew Elliott's result I did exactly the wrong

thing, maybe I should have stayed at home, maybe I should have

travelled south, maybe it would have been too cloudy, maybe... if

only...

Wind caused telescope to move most of the time. Some thin clouds

passing over the target, but always visible. Glare from Moon not too

much problem.

ADDITIONAL COMMENTS

 

The actual occultation was well defined in the drop in magnitude of the combined star/asteroid image. This combined image did blink once or twice at this instant? Seeing effect? Very short duration blinks. I did not see a well defined increase of the star/asteroid image and would appear to have been a gradual rise? So I could not determine the duration of the occultation. Just after the asteroid was seen separated from the star, I did see the star blink out towards the end of the observation but not sure if this was caused by poor seeing.
