Dear Sir / Madam ,
I would like study the photometry of the classical T Tau star - HM Luplong, a young M-type star as per the "Alert Notice 822 ". It has only 1070 observations in AID. I would like to do the photometry using VPhot.
For this purpose I am requesting you to get CCD images ( .fits or .fit format ) in B filter and V filter, using the facility of AAVSO observing campaign ( AAVSONet scopes ) .

The necessary information related to this study are as follows.
Hope you will guide me in this regard.
With regards,
Pradip Karmakar
