Following code is not able to scrap table from GCN due to occurrence of J. Bolmer on upper line.

See code 
using HTTP , CSV, DataFrames
function doanalysis()
    dfg=nothing
    for x in 26176
    print("\r peeking at GCN $x ")
        try
            url = "https://gcn.nasa.gov/circulars/$x/raw"
            resp = HTTP.get(url) 
            status=resp.status
            print(" ",status," "); 
            if status == 404 ; println("status=",status); continue; end          
            txt = String(resp.body)
            if occursin(r"GRB ?\d{6}([A-G]|(\.\d{2}))?",txt)
				m=match(r"GRB ?\d{6}([A-G]|(\.\d{2}))?",txt)
				print(m.match)
			end

            if occursin("GROND", txt)
                println(" GROND report")                
                he=first(findfirst(r"^(g'|r'|i'|z'|J|H|K)"m,txt))
                lr=first(findnext(r"^(((?:[\t ]*(?:\r?\n|\r))+)|(The)|(Given))"m,txt,he))-1
                cltxt=replace(txt[he:lr], "mag"=>" ",","=>"|",r" ?(=|>)"=>"|" , "+/-"=>"|","�"=>" ")
                df=CSV.read(IOBuffer(cltxt), DataFrame, delim="|" ,header=0)
                df.GCN=[x for i in 1:nrow(df)]
                df.GRB=[m.match for i in 1:nrow(df)] 
				rename!(df,"Column1" => "Filter","Column2" => "Mag","Column3" => "Mag_err")
				if isnothing(dfg) 
                    @show dfg=df
                else
                    @show dfg=vcat(dfg,df)
                end # if x is first
            end # if occursin
        catch e
            println("error ")                    
        end # trycatch
    end # for loop
end
doanalysis()

Above code is also not working for GCN-20843
