Jürgen Linder weist über die yahoo-Liste darauf hin, dass im neuen Einsendeformat der MPEC es nicht mehr gestattet, die aus dem visuellen Beobachterraum (sag ich mal) stammenden Helligkeiten m1 und m2 zu übermitteln. Wer das weiterhin will, muss das late Lochkartenformat benutzen.

"In the case of comets, the notations T and N stand for the total (m_1)
and nuclear (m_2) magnitudes, respectively."

Since 1978 the MPC has made the use of T and N mandatory for magnitude
estimates of comets.

In the new ADES format, the notations T and N are not supported. Rather,
a comet's magnitude is there expressed as a value in a given photometric-
aperture in a given band.

The MPC intends to end its enforcement of the use of T and N on comet
magnitudes effective Apr. 24.

Starting on the above date, observers should report comet magnitudes in
the same form that they report minor-planet magnitudes. See MPEC 2018-H21
for examples.

Observers who wish to continue using T and N may do so, for as long as
they report their observations in the 80-column format.
