AX PERSEI
This Z-And star appears to be now emerging from eclipse, somewhat
earlier than expected, as indicated by the following visual
magnitude estimates:  1988 Aug. 27.99, 9.5 (P. Schmeer,
Bischmisheim, West Germany; correction to IAUC 4685); Dec. 30.00
UT, 12.6 (Schmeer); 1989 Jan. 3.81, 12.5 (S. Korth, Dusseldorf,
West Germany); 13.89, 12.2 (A. Pereira, Linda-a-Velha, Portugal);
26.83, 12.6 (A. Boattini, Florence, Italy); Feb. 2.21, 12.8
(R. Royer, Wrightwood, CA); 8.03, 12.6 (J. E. Bortle, Stormville,
NY); 13.16, 12.6 (Bortle); 24.01, 12.3 (Bortle); 26.02,
11.7 (Bortle); 26.85, 11.9 (Schmeer).            IAUC 4745

R.Bouma, Netherlands, has telephoned through a report that this
UG star, on the recent La Palma Programme, has been seen in
outburst. On 1989 Feb 28 at 20.16UT he estimated it at magnitude
12.8v with the 0.25-m JB telescope. The La Palma programme finished
yesterday and if there are any unreported results for February
please e-mail these by March 2.

SN 1989B IN M66
To date, 107 results have been analysed suggesting that the
supernova is now fading slowly and reaching about 13.0 as at
yesterday. In good conditions, the star is difficult to estimate
against the background 'nebulosity' of the galaxy whereas
comparison stars do not suffer this problem. It is suggested that
those with larger telescopes stop the aperture down so that
the supernova is, say, about 0.5 magnitudes above the limit.
Alternatively it may help to use higher magnification to lessen
the 'background' effect. However this may place comparisons out of
the field and observers are reminded that they should always bring
the variable and then the comparisons to the centre of view when
making estimates.
Some observers have commented that star 6 is very faint but others
report that its position in the sequence seems correct. Comments
on this and the sequence as a whole are welcomed.
