and 2 positive:

          The actual central line ran about 45km north of the updated central line and predicted central occultation time error was < 5 s giving a total update error of ~0.03". Reduction of the observations by J. MANEK gives an elliptic shape of  108 X 61 km. MSI missed the shadow by less than a few hundred meters !

           MTN recorded an extinction on his CCD track but it is probably due to clouds.

GCV at Linhaceira N 39 31 22.6  W 08 23 01.5  +90m :

          [mp 0.22"  ±  0.03"  N of  * at 18 59 04  ±  7 s , from 19 CCD images]

          Slovakian positive observations confirm the J. Manek’s update but are incompatible with the GCV results. According to these, the real path should have been shifted by 1/2 path width South and 55 s. sooner relative to the update.

and 1 positive :

          As the speed of the shadow was of 5.62 km/sec, PNL chord measures 41.6 km. If the diameter of mp is 45 km, and with the hypothesis of a circular limb, PNL was at 8.6 km from the central line, either on the eastern or western side. The closest negative observation is the HJP one (57.9 km East of PNL chord), on the other side : KZA was at 76.4 km West.

All the results (GCV ant THU astrometric ones, positive observation of ANK and the numerous negative others) are consistent  with one path shift toward North and 4 s. advance relative to J. Manek’s update).

JLX recorded a blink (around 21 13 30) not confirmed by LAQ.

Several missions were planned in the southern hemisphere (Argentina, Brazil, Chile, Ecuador, Peru, Venezuela) and south Spain.  COF recorded an occultation from Arica, Chile :

Oscar Saa and Marc Buie from Lowell Observatory recorded an occultation from Iquique, about 300 km south of the Chile/Peru border.

JLX at pdm : N 42 56 10.8 E 00 08 32.2 +2880 m from 211 CCD frames (geocentric data)

            [Photocenter PLUTO+ CHARON 0.023" ±  0.015" (2 sd) S of  * at 01:44:36  ±  10 s]

            [PLUTO 0.012" ±  0.016" (2 sd) N of  * at 01:43:29  ±  12 s]

                So the central line of the occultation by PLUTO crossed Peru at 35 ± 350 km north of Lima.

Please send the reports quickly, about positive as well as negative observations !

A positive observation : an occultation is recorded;

A negative observation : the star remained visible throughout the survey.

Use the “Comments” to signal for instance : any doubt about the authenticity of the occultation, interruption in the survey (because of clouds,… : use the “I” and “J” timings).

Do not send a report if the observation is completely clouded out or the star unseen for any reason.

Please use the IAU format YYYYMMDD for the date. 04/05/03 is NOT 4^th of May 2003 !
