At first
column is indicated the interval that we must study from begin time to finsh time
each one hour at Universal. When we are finish
an observation, it's recommended to make intervals of one hour because the work will be
easier. Per exemple, at this case the begin time is at 22h.10m. & finish time was at
01h.18m. By the way, I've divided observation period in three intervals, each one of one
hour..
At second
column or field, we're noted the celestial coordenates, right
ascention & declinatioin of the vision field
during the observation. If we would changed
the fielf of vision during the night we must change, too, the interval to study
because it affects the results.
At third
column or Tef, we're noted the effective time of
observation, that is the all time between the begin time to finish time less the time we
write the characteristics of the meteor over our papers. The result must be write at
hours.
At fourth column
or F we're noted the
correction factor by clouds. It's recommended that each half hour we're noted the % of
cloud sky we have it, at this moment. To apply we must use next equation:
F=100/(100-K) |
where K is the % sky of clouds.
When K factor is more than 30 we must pause and we anoted over our Summary Paper this event.
At fifth column or M.L., we must note the limit
magnitude or MALE we have at this moment. On my web you can find more information & a
page to calculate the MALE. When there are more than one of MALE
medition during the same interval we must calculate the half value depending of
observation time. Per exemple, Between 22h.00m. to 23h.00m. we are noted two differents
annotations like: +5.8 at 22h.00m.; 6.1 at 22h.20m. & 6.3 at 22.h50m. By the way the
limit magnitude of this interval will be:
L.M.=(5.8 x 20) + (30 x 6.1) + (6.3 x 10) / 60; L.M.= 6.03 |
The calculate form the limit magnitude or MALE when at the same interval there're differents annotations, too, it's the same to calculate the clouds correction factor or F.
At fifth column we're noted by columns the active radiants during this
night, although we are not seeing any meteor of this radiant.
The metodology consists to put with the number of meteors of this radiant the P letter if we're drown in our maps or C letter if we've noted the datums but not drawing, only. It's recommended that at important radiants, per exemple, perseids, geminids, orionids, leonids, lirids it's made by counted or C.the observation and we're not drawing the treajectory becaue not louse effective time of observation.
At sisth column we're noted the same data that last one
but to sporadics meteors.
& Finally, at seventh column we are noted the total
of meteors seeing at this interval.

At Chart III, we're
classified each meteor with its magnitude with its radiant belongs. If one meteor we're
seeing with 3.5 magnitude, then, 0.5 belongs to third magnitude column & 0.5 to fourth
column magnitude..
Finally, at last colums we must put the total of meteors by radiant seeing during this night.

The Chart IV or the meteorology chart is very important to annotate our
observation.
At first column, we're noted the % of the Moon
durign the night. Positive sign means lunar phase is growing, with a valor of +100%
corresponding to full Moon. & negative sign means lular phase is decreasing. Per
exemple with a valor of -50% Moon is exactily last quarter.
Other values to add at this column are the luminosity and darkness of this night. The medition factor will be artificial light & transparency of the night..
At next
columns we are noted the K factor, corrector factor by clouds or the % of cloudy
sky about our vision field. It's recommended to annotate each half hour this factor.
& finally, at last column, we're noted some notes
that we want to say about the night.

of observation. & number of stars that it's visible ones. The MALE triangle must be
closed to the radiant. More information about how you can calculate the MALE, you can find
on my web.

& finally at Chart VI, we
must noted the meteors that they have trails, with their magnitude at their duration at
seconds. We must write one chart each radiant although the radiant there're not any
trails.
I hope it, with this intrucctions you can make more observations & it send us or send to diferents organitations like IMO.
