| This
update of the MAP Database contains 469 asteroids, then 27 more than the
previous database on June 30,2007 |
|
|
|
|
|
|
|
|
|
| This MAP
database nows contains 5138 measures (previously 4991 measures), than 147
complementary measures made since the last update. |
|
|
| In
addition to the measures of the 27 new asteroids entered in the MAP database,
many new measures have been made for 37 old MAP objets |
|
|
| On
the total of 469 asteroids of the database, 84 of them (17% of the total) now
have their original difference of magnitude explained by the natural
light |
|
| variability
or by some inaccuracies of measures and then now have no need of new
measures, while for about two tens objects, the MAP already has |
|
| a good
estimate of the difference of H magnitude. The revised H magnitude has been
published for 16 asteroids in the Minor Planet Bulletin 34-4 |
|
|
|
|
|
|
|
| On the 385
asteroids interested by new measures, the actual magnitude differences are : |

|
| Nearly
one hundred of MAP asteroids already observed during two oppositions wait
their third observed opposition to obtain probably |
|
| the
definitive confirmation of their H magnitude difference and the publication
of the results ! |

we shall be very interested by your new measures of the MAP objects in the

469 Astéroïdes et 5138

|
| Une
"LISTE récapitulative des astéroides du MAP" avec leur différence
actuelle de magnitude H figure sur les sites Web d'AUDE et de l'ALPO |
|
|
|
|
|
|
| Cette
mise à jour de la base du MAP comprend 469 astéroïdes, soit 27 de plus que la
base précédente du 30/06/2007 |
|
|
|
|
|
|
|
|
|
|
| Cette
base du MAP contient à présent 5138 mesures au lieu des 4991 mesures
précédentes, soit 147 mesures complémentaires depuis la dernière |
|
| mise
à jour de la base. |
|
|
|
|
|
|
| Outre
les mesures des 27 nouveaux astéroides entrés dans la base du MAP, de
nouvelles mesures ont été faites pour 37 anciens objets de la base |
|
| Sur
les 469 astéroides de la base, 84 d'entre eux - soit 17,9% du total - ont vu
leur différence d'origine de magnitude expliquée par la variabilité |
|
|
| naturelle
de lumière ou des imprécisions de mesures et n'ont donc plus à être mesurés,
tandis que pour près d'une vingtaine d'objets, le MAP a déjà |
|
| eu une très bonne estimation de l'écart de
magnitude H. La magnitude H révisée a été publiée pour 16 astéroides dans le
Minor Planet Bulletin 34-4 |
|
|
|
|
|
|
|
| Sur
les 369 astéroides restant à mesurer, les écarts actuels de magnitude sont : |

213 d'entre eux (45% du total), les actifs faiseurs de courbes de lumière ont
déjà permis la connaissance des données d'amplitudes |

|
|
|
|
|
|
|
|
|
|
|
|
| Une
partie des 469 objets du MAP ont déjà pu être observés à plusieurs

|
|
|
|
|
|
|
|
|
|
|
| Près
d'une centaine d'astéroïdes ayant déjà deux oppositions attendent donc une
3ème opposition observée pour avoir probablement |
|
|
| leur
écart de magnitude H définitivement confirmé et la publication de résultats ! |
|
|
|
|
|
| Nous
serons donc vivement intéressés par vos nouvelles mesures d'objets du MAP
dans le futur ! |
