Ja den ser rigtigt spændende ud:
an “Instant Cosmic Classic” Supernova skriver Berkley
an ‘Once in a Generation' Supernova kalder UCSB den

The PTF survey uses a robotic telescope mounted on the 48-inch Samuel Oschin
Telescope at Palomar Observatory in Southern California to scan the sky
nightly. As soon as the observations are taken, the data travels more than
400 miles to NERSC via the National Science Foundation’s High Performance
Wireless Research and Education Network and DOE’s Energy Sciences Network
(ESnet). At NERSC, computers running machine learning algorithms in the
Real-time Transient Detection Pipeline scan through the data and identify
events to follow up on. Within hours of identifying PTF 11kly, this
automated system sent the coordinates to telescopes around the world for
follow-up observations.
11kly er dermed ikke afstanden, men et løbenummer for det "event"
copmputerne havde fundet: Dvs. event numemr "kly" i 2011

Slå op på
apod.nasa.gov
for 26 aug.
Den forventes at blive mag. 10 indenfor nogle uger, og er type Ia.
Dens navn undrer mig lidt: PTF 11kly, PTF er det observatorie der opdagede
den.
11kly burde betyde 11 000 lysår, men galaksen er selvfølgelig flere mio ly
væk
Venligst
