Distant Comet C/2012 Q1 (Kowalski)

Comet C/2012 Q1 (LEMMON) taken 2012 Sep 02.01UT
2 images showing movement in 23 minutes.
Each frame is a 16 minute exposure with 0.40-m Schmidt-Cass. telescope & CCD
Original scale 2.14"/pixel, enlarged x4, field size 3.5x3.5 arcmin, North up
(c) P. Birtwhistle 2012, Great Shefford Observatory (J95)

Comet C/2012 Q1 (Kowalski) was discovered by Richard Kowalski using the 1.5-m Reflector on Mt Lemmon as a 19th magnitude object in Pegasus on 28 August 2012, 3 days before full moon. He described it as having a faint round coma approximately 20" in diameter (about double the diameter visible in the animation above)...........

Impact Risk Monitoring on 10 August '12

**Summary Risk Table for Risk Assessments Updated Today** (last checks: NEODyS and JPL at 0346 UTC)
See the CRT page for a list of all objects rated recently as risks and our ephemerides page for a list of risk-listed objects under current observation.
The time horizon for JPL is 100 years from today and for NEODyS is usually the year 2090. Both also post impact solutions beyond 100 years for a few special objects.
For the latest official risk assessments, and for explanations of the terminology, see the JPL NEO Program Sentry and NEODyS CLOMON2 risk pages.

An impact solution, also known as a "virtual impactor" (VI), is not a prediction but rather a possibility derived from a variant orbit calculation that cannot be eliminated yet based on the existing data. Elimination can come quickly with just a little further observation or may take weeks or months, sometimes years. Once superceded or eliminated, a former impact solution has zero relevance to an object's risk. See Jon Giorgini's "Understanding Risk Pages" to learn more.
