[vsnet-chat 5121] Re: (fwd) RV: [vsnet-obs 38590] Observations of 02/21/2002

["Maciej Reszelski" <macres@pro.onet.pl>]

Dear Taichi, Jose and Erwin,

 Taichi pointed out that some observations are
 not connected with others. Taichi also lists two
 IR Gem and SY Cnc. Both very often have major
 differences bitween estimations from other
 observers. I think the reason with IR Gem is
 simple - close star at 13.6 mag. PLEASE NEVER USE
 POWERS LESS THAN about 120x when observe this star!
 I think in SY Cnc case is existing(?) some different
 sequences for this one. PLEASE MAKE SURE STAR POSITION
WHEN YOU OBSERVING! Here are some examples from my mind
 stars with ' a trap':

 AB Dra - Do not confuse it with nearby 13.6!
 TZ Per -  A trap is 14.2 star very nearby
 RX And - simple but some guys may have a problem with nearby star...
 CZ Ori - Remember about 13th mag stars nearby
 SV CMi - 14.2 mag nearby..
  X Leo - 13.6 mag nearby, and this bright star on field don't make
          estimation easy...
 AT Cnc - similar star 'figure' nearby
 QY Per - faint 14.9 mag star nearby
 TW Tri - in faint 15.5 mag stars tringle. Really challange down than
15.5!!!
 RU Peg - 12mag star nearby. Often overestimated! See AAVSO disccusion group
Archive
          for details.
 EF Peg - 11mag star nearby
 HO Del - 15.2 mag star often misid with right HO Del!
 V1413 Aql - 13 mag star nearby
 V1141 Aql - Be careful! Rich-star field and many faint ones!
 V1113 Cyg - 13.6mag star nearby
 V1114 Cyg - Horror! Rich star field. For large scopes only...
 V811 Cyg - often my bad-friend! Bad AAVSO sequence Mike Simionsen made good
            job for new one! :)
 V1351 Cyg - no comment :) That's reason why I check this one time per year
session :)
 V1081 Cyg - I think for large scopes. Bright star very nearby.
 V1251 Cyg - In group of 14th mag stars...
 FX Cep  - Gary wrote me some time ago about faint star which can be misids
with FX
 HT Cas  - 13.9mag star nearby
 DK Cas  - Rich field, some similar figures nearby...
 KU Cas  - Star nearby!
