    Hi All
    
    While conducting my usual observation run last night I noticed during a 
    review of the data that GCOM W1, 2012-25A, 28337 is varying with a 
    regular rapid period of ~1.5 seconds.
    
    This caused me to Google what this s/c was as my habit is to investigate 
    what I see with a non-steady optical characteristic. I was struck by the 
    fact that this s/c was declared operational on just August 10, 2012.

    Seems odd to me that an operational s/c would have such a rapid visible 
    flash rate.
    
    Here is the ID frame and the 4 frame FITS file for those wishing to 
    investigate further:

    I can supply more data as my FOV was rather large last night and I have 
    in excess of 30seconds of data. Please request off list.
    
    Here's some positional obs from the frame linked here.

    For those interested in looking at the FITS files I'd suggest you use DS9:
