 Blazar 4C +31.03 (B2 0110+31) is having an unprecedented outburst.

Sebastian is in the process of putting this blazar into VSX and Elizabeth is developing a general Alert Notice. The J2000 coordinates are RA +01:12:50.34, Dec +32:08:17.4. Any UBVRI observations will be helpful. This object is rapidly brightening and may likewise fade quickly, so observations should be made within the next fer weeks. Thanks.

iTelescope observations....or not

Oh well, whenever I try to observe this with iTelescope, the site in question goes into maintenance mode ... arrrggggh.... does this thing have deadly coordinates or what :-/ .. Anyway, keep trying to observe this, hopefully with more success than me!
