> Observations Reported to the AAVSO: March 13.3 UT, <19.0: CCD, K. Itagati,
> Teppo-machi, Yamagata, Japan; 22.3, 14.9 CCD, Itagati; 22.444, 14.3 CCD,
> Itagati; 22.559, 15.5 CCD through clouds, Y. Kushida, Yatsugatake South
> Base Observatory; 24.1368, <14.9, M. Simonsen, Macomb, MI. (All
> observations from IAUC No. 8097, except the last reported to AAVSO HQ by
> M. Simonsen.)
>
> Notes:
>
> 1. M. Simonsen reports that supernova is currently difficult to observe
> with a 12" telescope and suggests that since the object is so close to the
> nucleus of NGC 3169 and since the galaxy is bright, it might become more
> apparent once it rises to a visual magnitude of ~14.5.
>
> 2. SN 1984 E also appeared in NGC 3169.
>
> 3. See the full announcement in International Astronomical Union Circular
> (IAUC) No. 8097.
