    Another nice image Mike!

    The (first) re-brightening started on May 6.910.

    An image from New Mexico (T14)  showing AL Com at the limit of detectability for 106 mm refractor with V filter. Still easily detected with a Luminance filter. Something for every section here with galaxies, a variable star, and  a tumbling object crossing the 300s exposure field. A second image also captured this object suggesting it was not a CCD defect or other anomaly.

    AL Com is heading down again, V=15.93 on 2019 05 16.918.

    I made it V=18.6 last night 23rd May so this may finally be the end of the outburst.

    A rather poor image attached taken at 07:04UT on 23rd May.  Illustrates that robotic telescopes don’t always return excellent results!  However, it is good enough to show that AL Com has faded significantly, as David’s photometry indicates, and is only just visible in this three minute exposure.
