[update] Another run performed during night 29.8.2011 revealed no source on the position. So it seems that is was rather an artefact after all... During observing run of M 101's supernova PTF11KLY (SN 2011fe) I noticed faint star-like object. As there is bad dark frame image used for reduction, I suppose that this is only some artefact. But other bad pixels seems to look different. This composed

As AT reported, there is a supernova Ia candidate in M101 nowadays. Of course, we should follow this as we do on SN in M 51 if weather permits. This is finder chart for our field of view prepared using Palomar DSS and position published in AT. click4detail As time is ticking by more info about supernova is available.

After few months of waiting we gathered all equipment we needed. CGEM Celestron mount is carrying 20cm f/4 (f=800mm) Newtonian from Bresser and AAVSO CCD SBIG ST-402ME. We suppose that this set-up would be enough to perform some exoplanet photometry (Honza) and variable stars/galaxies photometry (me).As a control PC we have MINI-ITX Atom PC with SSD boxed in a 3.5" floppy disk box (big one :).

During observing session of star in subj close companion showed some light variations. The star is: GSC=0096700904. There are two period candidates (using Peranso): 0.169d and 0.406d.Periodoigram using all available data from 30s exposures.Periodoigram from combined frames (3min exposure).Suspected variable star is marked by cross.First run.Second run.

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).

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

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 :)

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.

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.USNO

It reached max. aprox. 5.7mag so it become the brightest afterglow ever! Whole Earth is following this one so more exciting news appears frequently in my mbox.

Milos asked me to perform some B and V photometry of TW Dra during this week in part of www campaign. I centered the filed and found only 5 seconds B and 3 seconds V exposures with lack of any good comparison. This one could be better done on larger fov and / or smaller aperture. Anyway I'm lookin' forward on the results.

Today is expected European windstorm so I'm not optimistic about weather stability and suspect clouds or some rain to come. I imaged 3C 454.3 (reported bright by Uemura/VSNET), NGC 2770 (with two supernovae) and GR Tau ,,high-speed'' multicolor photometry.

I noticed clear sky at 1:16UT and put my underwear on. (Which made my girlfriend quite crazy...) At 1:53UT I was about 1km away from my bed and obtained first images of NGC 2770 with two lovely supernovas. Someone can think I'm not normal but I'm happy like that ;)Reducing available images of NGC 2770 I went into some troubles (data seems not homogeneous on multiple night scale). There is

Today it was promising to get some superb data but the weather. I did Stephan's quintet, NGC 2770 with supernovas, M 3. Seems that SN 2008D brightened but it needs time to get some precise results ;) Takin' all tha data files to my notebook and will try to do some work at home during weekend.

I tried to identify some faint stars on my image. I found SDSS image of NGC 2770 and labeled some faint sources (down to R band limit of our combined image). These are labeled on both images (white and red lines). It seems that faintest stars detected here in Brno (light polluted) on 40cm reflector using CCD ST7XMEi with R Kron-Cousins filter (not unfiltered!) is 19-19.5 mag (full Moon and not

Very unstable night with few nice windows in clouds. I went on NGC 2770 (with SN 2007uy and SN 2008D), in short moments when windows were only minimal I did M 42 and M 46. I also tried to get some flat with long exposure times (and in darkness) and after midnight I got few another NGC 2770 images.

Last two nights were quite good to get some magnitudes of two new supernovae. Since the Moon was close to max. phase and flats are not so good, resulting combined images are not as good as I hoped.

Very bad weather conditions. Moon and high altitude clouds make this night very poor. So I try to follow bright GR Tau again to catch some B-I data. Since the source and comparisons are very bright I can perform quite high speed (ha ha) photometry (5sI,10sB exps.) which can be interesting at secondary minimum phase where some asymmetry is observed. Asymmetry profile is wave length dependent so

After a month of bad weather I'm in a busyness again. Because the clouds leave the arena lately and conditions are not so good, I chose GR Tau to get some BVR coverage for this season (observing this one till 1996?).

V 455 And, clear filter, 15sec exposures as requested by Joe Patterson. It seems that our anti-wet solution is out tonight, all is wet and I need to solve it manually. Shame...

M 27 and 3c 454.3 and V 455 And. Seems to be nice night with almost full Moon... I tried also to operate 20cm (f=1000mm) Newtonian on EQ6 mount using SBIG ST-8 BVRI camera. Tonight I only focused the camera and performed some run on some Pegasus bright star and M 42 to get info about alignment. Seems that mount is not well aligned so more work on that needs to be done. Anyway quality of images

Long run of V 455 And again. Today I shortened exposures to 25 seconds to avoid 34 sec false alarm periods (as suggested by Joe Patterson in CBA chat mailing list). The night was very stable, dew of telescope is solved and pointing works well so the light curve is very precise (stars are bright of course). The video is very nice, satellites, air plain... nice...

After some sleep (finally) and cloudy weather I do today a run on V 455 And again. There were some clouds for some time at beginning of the run but they dissipated as Aladin predicted. I made simple shell script today for video of the whole run, so here we go :)[night profile]Combined imageV 455 And light curve 11.09.2007 12.09.2007 13.09.2007 14.09.2007 15.09.2007

Today I observed only V 455 And (R). The light curve is still very chaotic but the system is approximately 0.2 mag fainter than yesterday. Very high humidity and at the end of the run clouds again. I saw light curve posted by G. Massi and our data are very consistent! (why not :). I play with light curves for some time now. It's very interesting to compare behavior of stars with different color

What a date today... Well I did a long (4.4h) run on V 455 And (HS2331+3905) in R filter. Light curve and combined image will follow. M 27 (VRI), 3c 454.3 (VR) and short try on IC 10. Pointing of the mount seems to be perfect.[night profile]V 455 And vs comparison and check star.c1 - c2 is uncertain with (3sigma) 0.027 magV 455 And, 4.4h R band combined image.

I started with Nova Vul 07 under same conditions as I did last time. Then I moved on M 31 and made 20 min using both ST-7XMEi and ST-8 cameras (same config as last time). 3c 454.3 in V and R for a while. Then I wanted to make some pictures for fun so I moved the scope to California, M 45 and M 33 using both cameras. While imaging flats I used our webcamera SONY SNC20 to take this morning panorama

Right now I'm downloading sources of Xephem 'cause I need some real planetarium to use ;) Toys like stellarium or Kstars are of no use here... Observing Nova Vul 07 on 300mm tele using ST-8 camera gives me quite field of view with too many stars to get oriented. This nova is quite peculiar since it change it's brightness a lot on a scale of days and that's a reason to get some precise photometry

IGR[7] C observation. Night is clear and the narrow Moon just left the horizon... Hour before dawn I switched to M 15 (R) for a while...Add CY Aqr: I just finished some periodogames with Peranso. CY Aqr was found to be humping at aprox. 85.4 minutes which is in good agreement with literature. More precise result could be obtained while combined more nights, maybe I'll do some other run but it is

Tonite I made some mount experiments and wanted to go home... But suddenly clear sky was above so I switched the camera and telescope on again and right now I am performing some unfiltered observation of the IGR[9] field. It's quite suitable run, lookin' fward to examine combined images... I made also VRI short serie to get some color info about the bright objects and extinction artefacts...[

Some time after sunset the clouds defeated and quite dark night with lunatic Moon fall all around. So I cooled the camera and pinpointed M 27 (VRI), 3c 454.3 (VR) and CY Aqr (R).

Tonite I removed the camera and put the zoom eyepiece on our 40cm. Following some nice deep-sky objects I found 40cm to be very suitable for public observation. Night was not good so the real test need to be done in future. Now I put the camera back on and started run on 3c 454.3 in V, R bands. Seems that this blazar is fading now from current outburst.P.S. Need to get new R and V flats for this

Very short observing session. I stopped here on my way home to get 3c 454.3 V,R images and obtain dark frames to reduce last night (some software troubles - no darks were created at morning...). I watch Rolling Stones gig for a while - my parents lives close to the place so I had quite a seat :).

Today I'd like to continue with flat fields experiments which gave quite good result yesterday when I got just V flat and then switch the scope off 'cause of lightnings (visible on PV again...). It was really a great gig in the sky above Palava hills... Today I did the same experiment with B filter. After a while I moved over the Linear comet (C/2006 VZ13) to get aprox. 10 min exposure in R.Then

There is Mordor-like storm visible on the horizon... Radar data indicate this night will be short one ;) Running IGR[6] observation in V,R & I filters to get true (cha cha) colour image. As every night this week, no precise fast photometry to detect flickering is possible due to high clouds (and ligtnings tonite...)... Urgh&Beer...

Fast wind after lunch was caused by some cumulus clouds not fare away. This clouds went away just before midnight as predicted by Aladin. Cool... I started my run on 3C 454.3 in R and V bands. Since some clouds were all across the sky, certain exposures are affected (visualy confirmed during run) and will contain much more noise . Non stable conditions are also visible on PV measurement.Just

Tonight I performed run on IGRJ 23130+8608 [12] in R band to detect possible variations in a field. Just before dawn I switched to M 27 to check Goldilocks variable. Conditions were very good but visualy the sky has some strange opacity.Just after sunset we saw very thin Moon and Venus. Saturn and Regulus was too faint to capture (and I was too lazy to move myself to western roof to check it.)

Tonight we performed some tests with new pc in op. room. Seems that switching from temporary pc was successful. xmove works fine, same as other telescope apps... xnightview is still bit ill same as nihgt_batch which fails randomly to save a file (problem analysed ;).
