Good day. Colleagues do not tell me where you can find the highs and lows of Mirid for 2019? There used to be a bulletin, it came out at the end of February, but now on March 8 and it is not ... By the way, all women on a holiday !!!!
As we move deeper into 2019 it will get more difficult to effectively plan for observations. I sent an e-mail as well last week but no reply. Is everything OK? We need the bulletin or at least to know if there have been any problems in getting this published. Please advise as to the status and eventual expected publication of Bulletin 82.
The AAVSO Council decided to suspend production of the AAVSO Bulletin for 2019 (Bulletin 82). This decision was made as a result of having limited staff resources available at AAVSO HQ and having to complete certain projects in 2019.
We recognize that not having the Bulletin makes it more difficult to plan the observation of long period variables, and we apologize for this. There is a table of predicted maxima/minima of bright (magnitude 8 or brighter at maximum) long period variables for 2019 provided by the AAVSO in the RASC Observer's Handbook.

On the Swedish variable stars site SVO http://var.astronet.se there is a list with the brightest miras on the northern hemisphere right now. The list is updated each day and shows miras with estimated magnitude over 11 and list estimated dates of maximum and current magnitude.. The list has the heading "Aktuella miror". Maybe it could be of some use when the Bulletin is not available.
I used Bulletin preditions to my Astronomical Yearbook since 2015. (http://geocities.ws/costeira1/aac.htm). I created a single xls file to predict next maximum but it needs to entry last max date. So, the question now is "how to know the last maximum for several LPV?"
I have created an app that predicts 2019 max and mins for variables north of dec -20 that were included on previous Bulletins. You can download it from my Syzygy Shareware website at tcbretl.weebly.com. Go to the bottom of the Astronomy page. Both Mac and PC versions are available, but I have no idea whether the PC version works! I have only a Mac to use for testing .
Downloaded the PC version to my laptop...yes it works fine!! I'm a Mac guy, so will be heading to my desktop Mac to load it there too. Been exploring photometry this summer and LPVs have been my targets of choice. This will be a wonderful addition to my software tools. Thanks so much!!
