Object::

Neo Planner calculates observation times in R.A. order of currently visible comets according to the official publication of the MPC and additionally the most recently observed comets from CometasObs.
The reason for including the CometasObs observations lies in the sometimes considerable delay of the MPC in the publication of the last observations.

In addition, all NEOCP objects that can be observed according to the parameter settings are displayed.

In addition, visible NEOs are included that have not yet been numbered, i.e. have a provisional number.

Observation date and time in UT::

The optimal observation times of the objects are first calculated based on their meridian passage and thus the sequence is determined.
The observation time in UT is then calculated according to the calculated exposure times of all recordings.

RA and Dec:

The indicated position in R.A. and Dec. corresponds to the calculated Obs.time.
The position is not determined from the MPC NEOCP, but from the Scout Ephemeris page with an accuracy of 1 minute.

Altitude:

The altitude corresponds to the height of the object above the horizon at the time of the displayed observation time.

Moon Dis Alt :

The displays of the moon phase, the distance between the moon and the object in degrees and altitude of the Moon relate to the observation time and come from the Ephemeris Scout from JPL.

Vmag:

Comets: Average Vmag of the last 10 observations found in the MPC Database.
                If the MPC-Vmag is more than 0.5 mag brighter than the average Vmag, the MPC Vmag ist displayed and used for the calculation of the exposure time.


NEOs:   Average Vmag of the last 10 observations.
               If the MPC-Vmag is more than 0.5 mag brighter than the average Vmag, the MPC Vmag ist displayed and used for the calculation of the exposure time.
               If the MPC-Vmag is 1.0 mag weaker than the average Vmag, than the MPC Vmag ist displayed and used for the calculation of the exposure time.

NEOCP objects: Vmag of the Scout Query

s/min and PA:

The displays for arcsec / minute (s / min) and position angle (PA) refer to the observation time and come from JPL's Ephemeris Scout.

Exp.time:

A comprehensive description of the calculation of the exposure time can be found on the settings parameter for the sky background on the page for CCD parameters.

No. images:

The number of images is calculated by multiplying Number groups (No. groups) and images / group.

No. groups:

A comprehensive description of the number of groups can be found on the settings parameter for the sky background on the page for CCD parameters.

Neo Planner uses the entered value from the settings at speeds of the object greater than 3 arcsec / minute.
At speeds less than 3 arcsec / min. the value is multiplied by 2, at speeds less than 1 arcsec / min. the value is multiplied by 3 and at speeds less than 0.1 by 5.

The value of the group can be overwritten manually and adjusted according to your own taste. To do this, press the G key on the position line.

Images / group:

A comprehensive description of the calculation of the images per group can be found on the settings parameter for the sky background on the page for CCD parameters

NO GO:

W = at the suggested time there is a real risk that the object will cross the meridian.

F = the object was not found on the Scout page of the JPL, possibly a nonexistent object.
