    I got the alert from my asteroid-occultation group last evening.
    It was clear, but fog building up, so I didn't see it at 1-power.
    But in 7*50 it was so bright that I searched in vain for the comet
    to the right, towards delta Persei, before consulting the SkyMap plot again.
    Hope it doesn't fade too soon! from +16.9 to +2.4 (one observer) is about 
    700000* brighter!
