[Aavso-photometry] HD37605 photometry/possible Egress ???

[David Boyd]

Hi Gary,

Sounds interesting. I was clouded out last night (in UK) so can't corroborate. I 
got some data the previous night with no sign of a transit and I'm running again 
tonight. I guess we'll know for sure in 54 days ;-)

Clear skies,
David Boyd
