[vsnet-alert 263] update of the 2 Nov Alexis Transient

[droussel-dupre@lanl.gov (Diane Roussel-Dupre)]

In "[vsnet-alert 260] potential ALEXIS transient" we made a quick report of
a possible ALEXIS transient in which we requested follow-up observations.
This note will update what is currently known about the EUV emission
observed.

At 10:30 UT 2 Nov, 1995, the ALEXIS satellite observed enhance emission in
it's 66 ev telescope at the position:

Coordinates (2000)
R.A. 22 40 48.36
Dec  43 13 07.68

error circle 0.5 degrees.

The outburst continued until about 20 UT 2 Nov at which time it appeared to
turn-off in the EUV. Subsequent data does not show any additional EUV
emission from this location. The decay was an approximate exponential with
a 5.5 hour time constant.

Using other EUV sources in the detector FOV, we can refine the position to be

Coordinates (2000)
R.A. 22 42 24
Dec  42 57 43

error +/- 0.25 degrees.

I am grateful for Iida-san's quick response. I would appreciate copies of
his and any additional data that might be collected at this location. The
observer will be first contacted for permission to use the observations and
then credited for the observations if they are used in publications.
