III. Meteor classification

Which codes did you use to classify shower and sporadic meteors?
Also list codes that you tried to observe but did not produce meteors!
We recommend that you follow the IMO Working List.

	Code	Info
S1:		Enter shower code or SPO for sporadics
S2:		Enter shower code or SPO for sporadics

IV. Number of meteors per period

Periods should preferably not contain more than +/- 10 meteors or exceed 1 hour duration.
NEW: Field of view obstruction should be given as a percentage between 0 and 100 (replacing the F-value used in the past).

	Period (UTC)			Field of View		Teff	Obstr.
	hhmm	-	hhmm	RA (°)	Dec (°)	hours	%	P	N	P	N
P1:		-

V. Brightness distribution

Give the distribution of magnitudes per code and period. To reduce the input work, it is acceptable to combine periods into distributions of +/- 20 meteors.

	Shower	Periods			-4	-3	-2	-1	0	+1	+2	+3	+4	+5	+6	Tot
	Code	P#	-	P#	N	N	N	N	N	N	N	N	N	N	N	N
D1:			-
					Magnitude range: to
