[vsnet-alert 20468] b Per eclipse observations requested

[Donald Collins]

Hello, In a campaign with the AAVSO to observe b Persei, an eclipsing
3-star system, I am requesting world-wide observations of b Persei (see
AAVSO Alert notice: https://www.aavso.org/aavso-alert-notice-563 )
beginning immediately.  The eclipse is expected to begin any day this week
and lasting 2-3 days.  We are especially interested in wide geographic
coverage for this event.  Previous eclipses we were missing western North
America, Pacific nations, and Asian nations.  Please follow the protocol in
the alert notice.

Many thanks in advance,
Donald F. Collins
