The C.A.N.A. joins the E.A.O.N. (European Asteroidal Occultations Network). There, you can find loads of informations to follow this kind of events and a list to contact people involved in this activity. News are also available.

Program for the asteroidal occultations of 2010

Asteroidal occultation 89 Julia - TYC 2843-00046-1
28 october 2000
20:34 - 20:42 T.U.

Also this occultation was negative for our observation site (Salerno citycentre: Lat. N 40° 40' 53.8", Long. E 14° 46' 48.7"). At the moment we're not able to calculate the lowest angular distance between the asteroid and the star; however, we're developing an original software which will help us to take accurate astrometric measurements.
Anyway, here are some pictures of this event.

Asteroidal occultation 234 Barbara - TYC 6964-01174-1
25 october 2000
21:06 - 21:19 T.U.

That night, even clear, was troubled by blasts of wind which caused bad effects on the tracking during the exposures; however we managed to obtain acceptable images. Among those images, the following three.

The image processing confirmed our first sensation: the occultation was negative for our observation site (Salerno citycentre).

Asteroidal occultation 366 Vincentina - TYC 0598-01527-1
25 october 2000
21:43 - 21:55 T.U.

Unfortunately, we have only few images of this event, due to a sudden worsening of weather conditions, which prevented us to take exposures of the asteroid leaving the star. So we were not able to determine if the event was positive or not for our observation site.
The following image shows 366 Vincentina approaching the star.
Anyway, the shots we've taken mean a success for C.A.N.A. because they were taken while monitoring another occultation (234 Barbara - TYC 6964-01174-1, see the report above), quickly moving and pointing our telescope from a star fields to the other without any automatic drive system or digital circles.

20:27 T.U. CCD ST6 image - Meade 8" direct focus Exp: 10 sec.

Asteroidal occultation 409 Aspasia - TYC 5688-00868-1
18 october 2001
17:59 - 18:04 T.U.

17:41 T.U. CCD ST6 image - Meade 8" direct focus Exp: 20 sec.	18:38 T.U. CCD ST6 image - Meade 8" direct focus Exp: 20 sec.

After images processing (above are two of them), we have estimated that the path of the asteroid crossed the star: the event was positive for our observation site (Salerno citycentre)!
