UFO

During data reduction I noticed an object flying through the field of SDSS J152419.33+220920.0 on two of images. The object moved quite quickly (each exposure 60 sec.). Images are here and here. The direction was W->E, speed several angular minutes per minute (at least estimate).

SDSS J152419.33+220920.0

This dwarf nova went into suproutburst just after Joe Patterson et al. finished ,,big scope'' observation during it's quiescence. So there is a good reason to follow the star with our ,,small scope''. Doing long run photometry using R band filter as often as possible. Star shows periodic modulations of light curve (superhumps) combined with deep eclipses. The light curve is evolving during super maximum as will conclude light curves (hope soon prepared). During this campaign desiccant in camera went off and we experienced some mount troubles so the data are affected a bit. The Moon is also very annoying.

SN2009an

During end of March and April I followed supernova Ia in galaxy NGC 4332 designated SN2009an. Doing ( B)VRI imaging accorgind to meteo conditions.

GR Tau 4 Vladimir Znojil

Today's run is made in honour of Vladimir Znojil who left us much sooner then we thought and was burried just today. So Vladimir go to the GR Tauri system and look for yourself, I'll post obsolete light curve visible from Earth today soon. Rest in peace and shine on bright...

OT_J071126.0+440405 and KP Cas field

There are some new data of objects mentioned in topic available in archive now. Older data are processed for further light curve inspections. Run on OT is ruined by clouds a bit but reveals realy nice light variations moderated by deep (very) eclipses... Maybe some animation would be available soon :)

New variable in KP Cas field?

While inspecting preliminary data of KP Cas obtained here, I noticed USNO-A2.0 1500-00673609 in some sort of minimum. Since it can be some side effect of aperture photometry data will be analyzed more precisely. I also like to ask other ones observing this field to check for variability on their images. I include image and light curves.

First night the USNO star was constant...

V 1113 Cyg & unknown (?) field variable

We are following the superoutburst of V 1113 Cyg using our equipment. We have 4 nights of data up to now and weather promising. During data reduction we found faint variable star in the filed which seems to be not listed in variable stars catalogues. If you follow this superoutburst using your CCD, please include that star into your list too and share the data :) It is USNO 1425-09649996.

UPDATE: The star was preliminarily designated VSX J192242.3+524154 (AUID 000-BFV-196)and seems to be W UMa type variable with p=0.270(4)d with amplitude aprox. 0.4mag in R Cousins filter (Rmax=16.2::). We used Munipack for preliminary data procesing.

Preliminary R-band image
GRB 20080430 successful observation! Then we moved to M 82 because of transient reported via Atel 1501 alert. Data will be processed...

Telescope is up again...

thanx to mif and his osciloscope ;)

Telescope is down...

after some lightning close to our place electronics of 40cm telescope is down. seems that our observing season is off now for very long time...
