We have made some frames of V838 Mon in the I band early in the night, but
the star is too bright. We switched 40cm Brno telescope to this target and
are doing 20s exposures in the V band. The star is much brighter than 106
comparison on the AAVSO chart. We will write detailed report later.

Dear all,
we have preliminary reduced last 3.6 hours of our CCD V band observations
of V838 Mon. The star is brightening linearly with incredible rate of 2.37
mag/day (~0.1 mag/hour)! We will continue observing further...

Dear observers :
Just a few minutes I had seen the outburst of V 838 Monoceros.
The observation is :
20020202.8958 Mg. 8.5 AAAVSO chart d. 33.5 cms.
f/4.5 x 125. Comparison star 74 and 91
I had checked several times the star's field and clearly the
star is in outburst.

Subject: [vsnet-alert 7141] V838 Mon still rising!
Dear colleagues,
I just looked at this star by 25x100 binocular:
MONV838 20020202.969 81 L. Kral
I used 5 comparisons (mags from Tycho, recomputed to V).
I also started a CCD run on this star (at 22h UT), and
after 2 hours the preliminary light curve shows linear
rising trend at approx. 0.06 mag/hour!
A small photo-lens (with SBIG ST-7 and R filter of
RGB set) is used, so the high brightness of this star is
no problem for me.
I will send the resulting data to vsnet-campaign-data.
Best regards,
Lukas Kral

Dear all,
we have just finished our run on V838 Mon in the V band using 40cm
Newtonian telescope of N. Copernicus Observatory in Brno, Czech
Republic. We have obtained over 600 frames between 2002 Feb. 02.740 and
2002 Feb. 03.060 (UT). The star has brightened of about 0.56 mag
linearly. Using 10.6 comparison from the AAVSO chart (Henden
photometry) we estimate preliminary range 8.23 - 7.67 mag.
