NavList:

NOTE TO OUR MODERATOR :

AS KEEPS REGULARLY HAPPENING TO ME, IN NAVLIST 11996 SUBMITTED JUST A FEW MINUTES AGO, SOME DATA DISAPPEARED.

THEREFORE I AM SUBMITTING ENTIRELY THIS CURRENT POST

SORRY FOR SUCH DUPLICATION, BUT I AM NOT AWARE OF ANY OTHER WAY AROUND IT

Dear Sir,

In further reply to your post # [NavList 11986] Date: 22 Feb 2010 17:22 :

Thank you again for posting you own results about Jean Meeus's Aldebaran occultation example, in a post of yours to which I earlier to-day replied in post # [NavList 11991] Date: 22 Feb 2010 22:10.

Since you seem to have access to automatic software which gives you quick, easy and immediate replies, may I also respectfullly ask whether you could also rework our May, 22 Lunar occultation example by FN Captain Arago ?

You will find here after its relevant elements.

*******

Date and time 02 Mar 1901, (with TT-UT close to - 1.1 second of time)

Location, Brest in France

Latitude : NORTH 48 degrees 23 arcminutes 30 arcseconds, and
Greenwich Longitude : WEST 004 degrees 29 arcminutes 31.18 arcseconds, and Altitude : 0 meter, i.e. on the ellipsoid

Lunar occultation of the Star currently designated as k CNC (kappa Cancri).

This star is listed as follows in the following star catalogs : BSC #3623 / FK5 # 1238 / SAO # 98378 / HD 78136.

Its 2000.0 Mean elements are as follows : R.A.=09h07m44.819s *** µRA=-0.0014s/y *** Delta=N10°40'05.44" *** µDelta -0.01 "/y no parallax quoted.

With the elements hereabove, you should be fully able to uniquely identify this star.

THE FOLLOWING LINE GOT "SKIPPED" UPON INITIAL SUBMISSION, SO HERE IT IS AGAIN

Disappearance to occur at about 22h43m33.4s UT and Reapparence at about 23h59m31.4s UT

*******

My wish list here includes getting both Disappearance and Reapparence times in UT time scale. If you can use both software which you used for your post in [NavList 11986], I will then be able to check your k CNC apparent coordinates since at least one of the software you used yesterday prints out such data.

I found that my computed apparent position of k CNC is quite far off the one indicated by Paul Hirose. And since I reported this "discrepancy" earlier here in my post # [NavList 11971] Date: 22 Feb 2010 04:13, it has just lately come to my thoughts that the main reason for this noticeable difference between our both results might very well just be that Paul and I might not use exactly the same Precession elements.

*******

Meanwhile, thank you again for your Kind and Courteous Attention, and

awaiting your reply I am remaining

Most Sincerely Yours

Antoine M. "Kermit" Couëtte
