Dear Taichi,
last evening I detected what appeared to be CI Gem in
outburst (at mag 15-16) on a CCD image taken on Feb. 18.19 UT.
A few hours later the new object was confirmed on images
taken by Pepe Vilchez and Peter Sorensen with the Wide
Field Camera (WFC) of the Isaac Newton Telescope (INT)
at La Palma.
Please note that CI Gem is wrongly identified in Duerbeck's
nova catalog and in the catalog by Downes and Shara. My
object is slightly south of the marked star. Nothing is
visible at my position on the POSS image reproduced in
Duerbeck's nova catalog. So I would suggest a mag range
for CI Gem of 15 - [21.
You can find the INT images at:

r149876: Feb. 18, 23h33m UT, R, 150 sec
r149872: Feb. 18, 23h42m UT, B, 150 sec
I'll send you 'my' discovery and comparison images (both
taken by Mark Parker/Santa Barbara) separately.
Please inform your Japanese colleagues about this
extremely rare outburst (but please don't send anything
yet to VSNet). I'll send a more detailed report to
vsnet-alert within the next hour or so.
Best wishes,
Patrick
