The NMO Planning Tool for September is now online at http://vsnet.aavso.org/publications/bulletin/ The email discussion group has been rather quiet of late but the observations are still pouring in. In response to a couple questions about how the list is put together- I use the AAVSO Quick Look data only. So the status is based on what I find there and nothing else. If there are observations of a star that are <12.4 or <11.5 and no positive observations, I cannot determine if it is above or below the 13.5 cut-off, so they are marked NA (not available). I'm not trying to discourage anyone who has observed these fields and I am not ignoring your observations, I just can't use them to determine the status for the Planning Tool. Some specific stars that suffer from long term neglect are- T APS S AQR RV CAR RW CAR RY CAR RZ CAR R CHA R MIC R TUC S TUC T TUC U TUC To answer a question from Brian Skiff from last month (I didn't forget), I'm pretty sure the ASAS-3 data is in the AAVSO database, but I don't know that it is available in the LCG or Quick Look files per se. Maybe Aaron can enlighten us on this. One star had what looks to be discrepant data from a single observer- S Sgr. April 30 12.9 July 03 14.3 July 14 12.8 July 27 15.0 The period is listed as 230 days more or less. Maybe this CCD observer can go back and figure out what is actually going on here? Several good targets for CCD observers are quickly disappearing. Maybe you can get a few more observations of these faint Miras(<15.0) at minimum before they are lost to the sun. R SCO RT SCO Another interesting target for CCD early risers, that is not an NMO star, is SU Tau (R CrB). It has faded below my detection (<14.5) A whole new crop of variables is now visible before dawn. All of Eri, Aur, Ori (mostly) and Tau can be done before sunrise. Before long Gem and Mon will be available too. Go get 'em gang. Regards, Mike Simonsen
