TT Ari Campaign for the CBA
This isn't epsilon Aurigae related, but our friends at the Center for Backyard Astrophysics need help observing the cataclysmic variable star TT Ari for the next few days. See their latest e-mail announcement from their director, Dr. Joe Patterson:
TT Ari in Trouble
Or more correctly, our campaign. The weather in the southwestern USA
has "gone south" (forgive the parochialism), and will probably stay bad
for another 3 days. We really, really could use help from other
longitudes! Or latitudes. The eastern USA is getting battered by a
slow-moving storm... so I hope that other observers can carry this forward!
We did get NZ coverage last night from Bob Rea and Bill Allen. The star
remains more or less in that strange state I described... but it will be
a challenge to sort out the period/quasi-period of the huge humps -
given the unhappy P_rot and sometimes unhappy weather of our own planet.
What about the great expanses of Europe and Australia?
I am not a spokesperson for the CBA, so contact them for details regarding their campaign strategy. Traditionally, they accept both filtered and unfiltered obs. Use the AAVSO Variable Star Plotter to plot a chart and/or get photometry for comp stars.
If you aren't familiar with the CBA, they are a terrific group that focuses on CVs and have an excellent track record of producing results and papers galore. And Joe has one of the best senses of humor around. This is our chance to help our fellow variable star brethren! If you happen to get data, feel free to upload and discuss it here too. :) In fact, if you want us to send it to Joe on your behalf we'd be happy to.
