New observing of 29P/Schwassmann-Wachmann

P/2010 H2 (Vales) – 8 days after outburst

8 days passed from outburst of P/2010 H2 (Vales). This unusual comet was observed on April 23 with the 2.0-m Faulkes Telescope North. At this time, the comet has a very bright slightly elliptical central region some 4″x4″ in size  and the outer coma extends more then 40″x35″. We will continue observe this comet – perhaps newest member of Hylda-family comets. P/2010 (Vales) reaches perihelion around May 21.

Disappearance of fragment “b” of C/2007 Q3 comet

On images of C/2007 Q3 (Siding spring) comet, which taken on April 21 and 22 by FTN (Faulkes Telescope North) fragment b is not visible. Deconvolution of stacked 1 minute exposures not bring any results. Fragment b is disappeared…

Observation of P/2004 A1 (LONEOS) comet

The new attempt of observation P/2001 A1 (LONEOS) comet on 2-m FTN (Faulkes Telescope North). We taken 21 exposures by 30 seconds each. After stacking this images we obtain mag. limit about ~22m. The comet was not detected. P/2004 A1 located in very dense field, this factor complicate our surveying. At this time comet have ephemeris magnitude about 20.5m. P/2004 A1 (LONEOS) last observed on August 7 2007.

Confirmation of new SN2010br discovered in Belarus

I’m and Michael Schwartz confirmed new SNe in the NGC 4051 spiral galaxy. This SNe discovered by Byelorussian astronomy amateur Vitaliy Nevskiy. Spectroscopic analisys on Dominion Astrophysical Observatory, shows the spectrum to be similar to that of a type-Ib/c supernova.  Comparison with a library of supernova spectra using the “superfit” matching program indicates that SN2010br is similar to the type-Ib/c supernova SN1987K. This supernovas practically haven’t hydrogen lines in the spectrum and progenitors of this SNe is very old and massive stars. On the discovery moment, the SN2010br have magnitude about R = 17.1m и V = 17.7m.
