AAVSO Chart(s): No AAVSO chart has been made yet for this object. Chart options are being investigated. Keep watching the AAVSO website and the AAVSO Discussion Group for chart information.
Report Object to the AAVSO as: 0914-29 N PYX 05
Observations Reported to the AAVSO: March 5.259 UT, (14.0 V, ASAS; 14.260, 12.4 V, ASAS; 15.00, 12.6 V, ASAS; 16.00, 12.8 V, ASAS; 16.451, 12.8 CR (unfiltered CCD, red magnitude).
Notes (from IAU Circular 8495):
a. H. Yamaoka provides the following position end figures by K. Itagaki, Teppo-cho, Yamagata, Japan, using a 0.60-m reflector, from his own unfiltered CCD image taken on March 16.451 UT: 58.50s, 37.0".
b. H. Yamaoka adds that Itagaki's position is close to the northern star (blue mag about 18.0) of a close double on the Digitized Sky Survey.
Congratulations to ASAS and H. Haseda on their independent discoveries!

16.819, 11.9, Schmeer
16.823 UT, 12.0, Renz
Position: R.A. (2000): 05h 32m 33.87s Decl. (2000): +62o 47' 52.1", by P. Schmeer
Chart(s): A chart prepared by M. Simonsen is available to [cvnet-discussion] group members at the url below: http://groups.yahoo.com/group/cvnet-discussion/files/

Report Object to the AAVSO as: 0523+62 RXSJ053234
Note: Time-series CCD photometry is particularly requested to help determine the CV sub-type of this new CV. Visual observations are also strongly encouraged!
Over the past several months, on behalf of our colleague Dr. John Cannizzo, NASA Goddard Space Flight Center, we had asked you to monitor the cataclysmic variable U Gem closely and report its going into outburst. He had planned to observe U Gem on its next outburst with RXTE on a Target Of Opportunity (TOO) observing campaign.
When U Gem went into outburst on February 20, 2005, you notified us promptly and we notified Dr. Cannizzo at once (fortunately he was home on a Sunday afternoon!). He contacted the RXTE scheduling team immediately, but, most unfortunately, they were not able to divert from the target they were observing in time for the satellite observations to be at the phase Dr. Cannizzo wanted to study, so the request was cancelled. Please don't be discouraged that the TOO observations did not happen this time. It is disappointing, but sometimes TOO observations simply are not feasible when the target presents itself.
It is hoped Dr. Cannizzo will be able to obtain satellite observations of U Gem when it next goes into outburst, please continue to monitor U Gem closely, and inform us immediately when it brightens to magnitude 13.5 or brighter. Both visual and CCD observations are encouraged. NEW CHARTS FOR U GEM WERE ISSUED IN FEBRUARY 2004, and are available on the AAVSO website. Please make sure you are using these latest charts. If you do not have access to the website, please contact Headquarters and ask for the new charts to be sent to you.
The tremendous coverage - both visual and CCD - of U Gem during these past months, and particularly during the last outburst, is a real testimony to your dedication, enthusiasm, and patience. On behalf of Dr. Cannizzo, and personally, thank you very, very much.
SUBMIT OBSERVATIONS TO THE AAVSO
We encourage observers to submit observations via our web site (online data submission tool WebObs), or by email in AAVSO format to firstname.lastname@example.org. If you do not have AAVSO Observer Initials, please contact Headquarters so we may assign them to you. The answering machine at AAVSO Headquarters is on nights and weekends; use our charge-free number (888-802-STAR = 888-802-7827) to report your observations, or report them via fax (617-354-0665).
Many thanks for your valuable astronomical contributions and your efforts.
