>Dear Taichi,

> I send you observation made by me on last night:

>New nebula IRAS 05436-0007 near M78

> CCD R-band total magnitude:

>Feb. 11.913, 13.21 +/- 0.05.

>Total magnitude of nebula (including stellar objects in nebula) was

>measured in circle aperture of diam. 80".

>Size of nebula in N-S direction: 80"

>Size of nebula in E-W direction: 65"

>In nebula is 6 sources which size is same as stellar images of same

>approximate brightness (R-band mag about 15-19). It does not mean, of

>course, that all of them must be a stars.

>All was measured on coadded 20x30-sec image taken with the 0.35-m reflector

>at Lelekovice, Czech republic.

>Best wishes,

> Kamil Hornoch
