vono to bylo moc dlouhy, a rudolf nestiha administrovat, ja to vcera psal,
kde FH (pamatuje se to snadno jako Filip Hroch) na nebi je. Toz jsem
zvetsil limit z 10 na 15 KB, ted by to melo projit

(... ja to posilal uz pred chvili, ale mel jsem spatne filtraci html kodu
do mailinglistu, ted by to melo projit. Nebude neviditelna u nas jen
"prakticky", ale s jistotou vubec, prakticky pak ani odjinud z Evropy nebo
USA, pokud neleti jinudy...)
No, ta planetka videt u nas, ani nikde v nasich sirkach, nebude
("kulminuje" dnes asi stupen vysoko a maze mezi stalicemi tempem deset
stupnu za hodinu), vcera byla zachytitelna (ale neviditelna, 15 mag) nekde
ve Vahach, zase bude nad obzorem, ale jeste slabsi. Blizko zeme (a 10 mag)
bude hluboko na jihu. Videt pritom bude z africkych a americkych tropu a
jizneji.
Byl to zbytecny humbuk pro nas severany.
Ja napred myslel, ze videt bude, ale to byla defaultni JPL efemerida pro
dve minule pulnoci... uz jsem par lidi dezinformoval, tak to napravuju.
JPL efemeridy jsou pretizene, MPC zase havaruji (jen castecne vystup,
jinak funguji) na male vzdalenosti planetky od nas. JPL vystup pripojuju.

Column meaning:
TIME
Prior to 1962, times are UT1. Dates thereafter are UTC. Any 'b' symbol in
the 1st-column denotes a B.C. date. First-column blank (" ") denotes an A.D.
date. Calendar dates prior to 1582-Oct-15 are in the Julian calendar system.
Later calendar dates are in the Gregorian system.
The uniform Coordinate Time scale is used internally. Conversion between
CT and the selected non-uniform UT output scale has not been determined for
UTC times after the next July or January 1st. The last known leap-second
is used over any future interval.
NOTE: "n.a." in output means quantity "not available" at the print-time.
SOLAR PRESENCE
Time tag is followed by a blank, then a solar-presence symbol:
'*' Daylight (refracted solar upper-limb on or above apparent horizon)
'C' Civil twilight/dawn
'N' Nautical twilight/dawn
'A' Astronomical twilight/dawn
' ' Night OR geocentric ephemeris
LUNAR PRESENCE
The solar-presence symbol is immediately followed by a lunar-presence symbol:
'm' Refracted upper-limb of Moon on or above apparent horizon
' ' Refracted upper-limb of Moon below apparent horizon OR geocentric
ephemeris
R.A._(J2000.0)_DEC. =
J2000.0 astrometric right ascension and declination of target. Corrected
for light-time. Units: DEGREES
Azi_(r-appr)_Elev =
Refracted apparent azimuth and elevation of target. Corrected for light-time,
the gravitational deflection of light, stellar aberration, precession, nutation
and approximate atmospheric refraction. Azimuth measured North(0) -> East(90)->
South(180) -> West(270), elevation with respect to plane perpendicular to local
zenith direction. TOPOCENTRIC ONLY. Units: DEGREES
APmag =
Asteroid's approximate apparent visual magnitude by following definition:
APmag = H + 5*log10(delta) + 5*log10(r) - 2.5*log10((1-G)*phi1 + G*phi2).
Units: none
delta deldot =
Target apparent range ("delta") and range-rate ("delta-dot") relative to
observer. Units: AU and KM/S
Cnst =
Constellation ID; the 3-letter abbreviation for the constellation name of
target's astrometric position, as defined by IAU (1930) boundary delineation.
See documentation for list of abbreviations.
