Results from the Calar Alto observing campaign

1999 CV8 recovery prediction for June 20th, 2001 at 014010 UT (designed with EasySky developed by Matthias Busch)

Target overview:

recovery NEO        :  14 targets
recovery UNUSUAL    :   4 targets
recovery COMET      :   4 targets
followup NEO        :  41 targets
followup NEOCP      :  22 targets
verfication of IDs  :  25 targets
new discoveries     :   9 targets
others              :  14 targets

Observing strategy:

To recover a target we observe along the LOV starting from the centre. Normally we take 2 or 3 images of each field. An installed IP connection between the telescopes imaging computer and the review team (A. Doppler, A. Gnädig and R. Stoss) located in Germany allows a quasi simultaneous inspection and measurement of the images right after the exposure. When the target is detected the search along the LOV is stopped and the observing team looks for another object (e.g. from the NEOCP) until the next planned recovery or follow up attempt has to be started.

Some of the NEO recovery targets were very faint and fast moving. We are using the "track and stack" technique utilized in the latest version of Herbert Raab's software package Astrometrica , to improve the S/N ratio of the detection. In this way it was possible to observe FMOs as faint as about 22 mag. Some introduction about "track and stack" you can find here .

Robert H. McNaught (413) and Erich Meyer (540) reported one night observations of J88R01O and J99Y00A before. Using this observations it was quite easy to get the 2nd night observations for completing the their recovery attempts.

Special Note:

2nd night wanted for 1999 GT3.
