Houston Date: Tue, 6 Apr 93 23:13:43 GMT For those of you who haven't seen the new supernova in M81, don't wait for a moonless night. It's fading fast! Last night (April 6.26 UT), I estimated its magnitude at 11.7 using the chart provided in AAVSO Alert Notice 169. I've read postings of estimates as high as 10.5, and there was some speculation that it might reach magnitude 8 or 9.

Yes, please do. It would be an honor! The telescope I used was a 28 cm schmidt-cassegrain. If you need more information, just ask. Here is another visual observation of mine (this time with a 25.4 cm schmidt- cassegrain telescope): April 11.21, magnitude 10.9. I have made several other visual observations, which I will send you after checking my records. This supernova has brightened continuously since I posted my first observation - interesting behavior! Bonsai! and clear skies, Bill
